- In Java, the `this` keyword is a reference to the current object within a non-static method or constructor. It represents the instance of the class on which the method or constructor is being called.
- When a class is instantiated to create an object, that object has its own set of instance variables and methods. The `this` keyword allows you to refer to those instance variables and methods from within the class itself. It is primarily used to differentiate between instance variables and parameters or local variables that have the same name.
- Here are a few common uses of the `this` keyword in Java:
collapsed:: true
- Accessing instance variables: You can use `this` to access or modify the instance variables of the current object. For example, `this.variableName` refers to the instance variable `variableName` of the current object.
- Invoking constructors: In a constructor, `this` can be used to invoke another constructor in the same class. It is useful for constructor chaining, where one constructor calls another constructor to initialize the object.
- Passing the current object as a parameter: Sometimes, you may need to pass the current object as an argument to another method. In such cases, you can use `this` to pass a reference to the current object.
- Returning the current object: A method can use `this` to return the current object. This is often used in method chaining, where multiple method calls are chained together on the same object.
- It's important to note that `this` can only be used within non-static contexts, as it refers to the current instance of the class. Static methods and variables do not belong to any specific instance, so `this` cannot be used inside them.
- Overall, the `this` keyword provides a way to refer to the current object and access its members, helping to avoid naming conflicts and make the code more readable.

- Inheritance in Java is **a concept that acquires the properties from one class to other classes**
- ## polymorphism
- encapsulation
- Encapsulation in Java is a mechanism of **wrapping the data** (variables) and code acting on the data (methods) together as a single unit. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class. Therefore, it is also known as **data hiding**.
- abstraction.
- Data **abstraction** is the process **of hiding certain details** and showing only essential information to the user.
- Abstraction can be achieved with either **abstract classes** or
[**interfaces**](https://www.w3schools.com/java/java_interface.asp) (which you will learn more about in the next chapter).
- Overloading vs. overriding
- When two or more methods in the same class have the same method name but different parameters, this is called overloading. In contrast, overriding occurs when two methods have the same name and parameters

- Research paper introductions are always unique.
After all, research is original by definition. However, they often
contain six essential items. These are:
- **An overview of the topic.**Start with a general overview of
your topic. Narrow the overview until you address your paper’s specific
subject. Then, mention questions or concerns you had about the case.
Note that you will address them in the publication.

other conclusions on your topic. Include both older scholars and modern
scholars. This background information shows that you are aware of prior
research. It also introduces past findings to those who might not have
that expertise.
- **A rationale for your paper.**Explain why your topic needs to
be addressed right now. If applicable, connect it to current issues.
Additionally, you can show a problem with former theories or reveal a
gap in current research. No matter how you do it, a good rationale will
interest your readers and demonstrate why they must read the rest of
your paper.
- **Describe the methodology you used.**Recount your processes to
make your paper more credible. Lay out your goal and the questions you
will address. Reveal how you conducted research and describe how you
measured results. Moreover, explain why you made key choices.
- **A thesis statement.**Your main introduction should end with a
thesis statement. This statement summarizes the ideas that will run
through your entire research article. It should be straightforward and
clear.
- **An outline.**Introductions often conclude with an outline.
Your layout should quickly review what you intend to cover in the
following sections. Think of it as a roadmap, guiding your reader to the
end of your paper.
- These six items are emphasized more or less,
depending on your field. For example, a physics research paper might
emphasize methodology. An English journal article might highlight the
overview.

Ref: Negligence of duty by the staff in our Uttara Showroom.
Dear Sir,
In accordance with” your instructions, I personally visited our Uttara
showroom to look into its functioning. I made some investigation and
therefore submitting my report hereunder. <abstract,introduction>
A number of worthy customers purchased some exclusive garments
but found some problems with fitting after purchase. They tried their
best to return the garments but failed because there was no
attendant to take the complaint and providing the change. As a
result, they made a phone call to our complaint department and filed
complaints regarding this issue. <findings>
In our Uttara branch, there is only one attendant named Mr. Saker to
handle the after-sales service. He has been found to be irregular for
the last three (3) months. As a result, our customers are getting
dissatisfaction causing a decrease in our sales. In this age of
competition, losing customers means “Red Alert to the business.
I have no hesitation to recommend that Mr. Saker may be served
with a notice and a really efficient and active man may be sent there
for proper functioning. <recommendation>
I hope that quick action will be taken based on my recommendation
for the betterment of our company.<close>
Yours faithfully

- Database is :-> a shared collection of logically related data (and a description of this data), designed to meet the information needs of an organization.
- Index :-> A data structure that improves the retrieval speed of data from a database table by creating a quick reference to the location of the data.
- SQL (Structured Query Language) :-> A programming language used to manage and manipulate relational databases. It allows you to create, modify, and retrieve data from databases.
- Database Management System (DBMS) :-> Software that provides an interface to interact with databases, managing their creation, modification, and retrieval.
- disjoint constraints :-> Describes relationship between members of the subclasses and indicates whether member of a superclass can be a member of one, or more than one, subclass. #flashcard
- Maps the conceptual data model on to a **logical model (e.g. relational)**, but i*ndependent of a particular DBMS and other physical considerations*.
- DONE ACID (Atomicity, Consistency, Isolation, Durability): A set of properties that guarantee the reliability and integrity of database transactions. #flashcard
- Atomicity: :-> The property that ensures a transaction is treated as a single, indivisible unit of work. It either executes all its operations successfully or rolls back to the initial state if any operation fails.
- Consistency: :-> The property that ensures a transaction transforms the database from one consistent state to another consistent state. It maintains data integrity and adheres to defined business rules.
- Isolation: :-> The property that ensures concurrent transactions do not interfere with each other. Each transaction operates in isolation until it completes, preventing interference or conflicts.
- Durability: :-> The property that ensures committed changes made by a transaction are permanently saved and will survive any subsequent system failures or crashes.
- In a relational database management, functional dependency is a concept
that specifies the relationship between two sets of attributes where one
attribute determines the value of another attribute. It is denoted as **X → Y**, where the attribute set on the left side of the arrow, **X** is called **Determinant** , and **Y** is called the **Dependent**.
normalization. In 1NF, each table cell should contain _only a single value, and each column should have a unique name_. The first normal form helps to eliminate duplicate data and simplify queries.
- Second Normal Form (2NF): :-> 2NF eliminates redundant data by requiring that each _non-key attribute_ be ==dependent on the primary key==. This means that _each column should be directly related to the primary key_, and not to other
that _all non-key attributes are **independent** of each other._ This means that each column should be **directly related to the primary key**, and not to any other columns in the same table.
- Boyce-Codd Normal Form (BCNF): :-> BCNF is a stricter form of 3NF that ensures that each determinant in a table is a candidate key. In other words, BCNF ensures that _each non-key attribute is dependent **only on the candidate key**._
- Fourth Normal Form (4NF): 4NF is a further refinement of BCNF that ensures that _a table does not contain any multi-valued dependencies._
- Fifth Normal Form (5NF): 5NF is the highest level of normalization and involves decomposing a table into smaller tables to _remove data redundancy and improve data integrity._
- You can: design ways of describing information (text or data), usually for storage, transmission, or processing by a program (you can use it in combination with a programming language).
- It says nothing about what you should do with the data (although your choice of element names may hint at what they are for).
- Project planning involves scheduling the project tasks and determining resource requirements. The project plan is first laid out during the concept development phase, although it is a dynamic entity and continues to evolve throughout the development process.
- Project execution, sometimes called project control, involves coordinating and facilitating the myriad tasks required to complete the project in the face of inevitable unanticipated events and the arrival of new information. Execution is just as important as planning; Many teams fail because they do not remain focused on their goals for the duration of the project.
- **Project Planning**: Understand and represent different tasks in projects
- A project task is assigned to a row and a corresponding column.
- The rows and columns are named and ordered identically, although generally only the rows list the complete names of the tasks. Each task is defined by a row of the matrix.
- We represent a task’s dependencies by placing marks in the columns to indicate the other tasks (columns) on which it depends.
- Reading across a row reveals all of the tasks whose output is required to perform the task corresponding to the row.
- Reading down a column reveals which tasks receive information from the task corresponding to the column.
- The diagonal cells are usually filled in with dots or the task labels, simply to separate the upper and lower triangles of the matrix and to facilitate tracing dependencies.
- PERT (program evaluation and review technique) charts explicitly represent both dependencies and timing, in effect combining some of the information contained in the DSM and Gantt chart.
- The _dependencies_ among the tasks in a PERT chart, some of which may be arranged sequentially and some of which may be arranged in parallel, lead to the concept of a critical path.
- The _critical path_ is the longest chain of dependent events. This is the single sequence of tasks whose combined required times define the minimum possible completion time for the entire set of tasks.
- **Definition** :-> project plan is the roadmap for the remaining development effort. The plan is important in coordinating the remaining tasks and in estimating the required development resources and development time.
- Product development time is often the dominant concern in project planning and execution. There are a set of guidelines for accelerating product development projects.
- Smooth execution of even a well-planned project requires careful attention. Three problems of project execution are particularly important: 1. What mechanisms can be used to coordinate tasks? 2. How can project status be assessed? and 3. What actions can the team take to correct for undesirable deviations from the project plan?
- Workshops with **multi-voting**: collaborative sessions or meetings where participants engage in a voting process to prioritize or make decisions on various options or ideas.
产品规划 (product planning)流程发生在一个产品开发项目正式启动，大量的资源开始使 用及更大的开发团队形成之前。该流程将确定一个公司应该从事的项目组合 (portfolio, 或译 为项目投资组合),并决定什么时候从事什么子项目。产品规划流程确保产品开发项目可以支持公司未来更多的商业策略·This phase takes place before a product development project is formally approved·It takes place before substantial resources are applied ·It takes place before the larger development team is formed ·Product planning is an activity that ·considers the portfolio of projects that an organisation might pursue. i.e. what mix of new products and markets to develop, if they focus is on basic or applied research or diversification projects and ·determines what subset of these projects will be pursued over what time period
- 规划流程始于对产品开发机会的识别，这种机会可能包括上述四种类型项目中的任何一 种。这一步可以看成是机会漏斗 (opportunity funnel), 因为它将来自整个公司的各种投入汇聚到一起。每个想法应该有一个简短的描述，包括产品概念、市场机会等。把这些想法方放到一起然后进行筛选·The first stage of the planning process is to identify product development opportunities·Each of the ideas should be expanded into a short description – including the potential business opportunity·These ideas can then be stored and revisited later·Each of the ideas should have a ‘champion’ who is responsible for supporting the idea through theprocess
- 如果能实施有效的管理，机会漏斗在一年中可以收集成百上千个机会，这些机会中有些对于企业的其他活动没有意义，因为在多数情况下，有太多的机会要求企业立即去把握。因 此，产品规划流程的第二步就是要选出最有希望的项目。对已有产品领域中新产品机会进行 评价和优先级排序时，需要仔细讨论以下四个基本方面：竞争策略、市场细分、技术曲线和产品平台。·In this step, the organisation is looking to decide which of the projects to pursue·There are four perspectives that can be used to assist in the evaluation and analysis of each of the projects l Competitive strategy l Market segmentation l Technological trajectories l Product platforms在这么多提交上来的想法和项目中你要进行选择，选择一个好的项目最主要的是看它能不能挣钱。可以从以下四个角度去思考：1.技术曲线：有没有能力做成这个项目 2.产品平台：能不能做成一系列产品 3.市场细分：产品投放到哪，以及市场定位是什么 4.竞争策略：怎么在同类型产品中脱颖而出，占据市场
- * ● 技术优势 (technology leadership): 为实施这一策略，企业必须强调新技术的研究和开发，并将其应用到产品开发流程中。 A focus on basic research and development of new technologies
- * ● 成本优势 (cost leadership): 这一策略要求企业在生产效率上进行竞争，可以实行规模经济，使用先进的制造方法和低成本的劳动力，或者引入更好的管理生产系统。Competitive focus on production efficiency
- * ● 以顾客为中心 (customer focus): 为实施这一策略，企业必须跟新老顾客保持密切联系以评价其需求和偏好的变化。精心设计的产品平台有助于快速开发拥有满足顾客 偏好的新特点或新功能的派生产品。这种策略将造就用来满足不同层次顾客需求的多种产品生产线。 The organisation works closely with customers to assess changing needs and preferences
- * ● 模仿策略 (imitative): 这一策略要求紧跟市场趋势，允许竞争者探索每一部分已获成功的新产品。当确定了可行机会之后，企业快速开始模仿成功竞争者的新产品。快速的 发流程对于这一策略的有效实施至关重要When a clear opportunity has been identified and has been successful, the organisation launches a competitive version.
- * 市场细分Market Segmentation一般认为顾客属于市场的不同部分。把市场分为不同的部分，使企业能够按照各详细定义的顾客群来考虑竞争者的行动和企业已有产品的市场力度。通过将竞争者的产品和企业自己的产品对应到各个细分市场，企业就可以评价哪些产品机会最好，以揭示出企业自身的(或竞 争者的)产品生产线问题Divide the market into segments in order to be more focused on the customer and competitors
- * 技术曲线Technological Trajectories在技术密集型企业，产品规划的关键决策是什么时候在生产线上采用一种新的基本技术。When to shift to implementation of the new technology as part of the core product range
- ● 企业中冠军产品 (product champion) 的存在l Market size (units/year x average price)l Market growth rate (percent per year)l Competitive intensity (number of competitors and their strengths)l Depth of the firm’s existing knowledge of the marketevaluation criteria (contd.)l Depth of the firm’s existing knowledge of the technologyl Fit with the firm’s capabilitiesl Fit with the firm’s other productsl Potential for patents, trade secrets or other barriers to competitionl Existence of a product champion within the firm
- 资源分配Resource Allocation如果公司开发太多的项目而不考虑开发资源的有限性，那么有经验的工程师和经理就会被分配到越来越多的项目上，生产效率急剧下降，项目完成时间延长，产品上市迟缓，利润水平低下。l Over commitment of resources will inevitably lead to a drop in productivity l An example of over commitment would be allocating engineers and managers to more than one project (where they are already at full capacity working on one)
* product planl This is the set of projects approved by the planning processl These are sequenced in time l The plan may include a mix of fundamentally new products, platform projects and derivative projects l The updating of these plans is usually undertaken on a periodic basis e.g. quarterly or annually（这个同样不属于资源分配和时间安排里的两步，但是PPT放上去了）
* 当项目确定下来，但是还未进行物质资源的分配时，就需要进行项目前期规划。这一过程涉及一个小的跨职能团队，通常被称为核心团队 (core team)，分别代表技术、市场、制造和服务部门等多方。¡ After project approval, but before the commitment of resources, a pre-project planning activity takes place¡ This activity involves a small, cross-functional team – the Core Team
- * ● 对产品的概括性描述 (用一句话描述):这一描述通常包括产品的主要用途，但要避免包含特定的产品概念。实际上它可以是产品的前景说明。 A brief description of the product
- * ● 获益方案 (或称为获益建议， benefit proposition): 这一部分阐述了顾客会购买商品的几个关键原因。Typically includes the key customer benefit of the product
- * ● 主要商业目标： 除了支持公司战略的项目目标之外，这些目标通常包括时间、成本和质量目标(如产品的上市时间、预期财务效益和市场份额目标等)。 ¡ The goals which support the corporate strategy ¡ The goals for l Time e.g. timing for product introduction l Cost e.g. desired financial performance l Quality
- * ● 产品目标市场： 每一种产品可能会有几个目标市场。任务陈述的这一部分确定了一级市场和二级市场。 Target market for the product Primary and secondary markets that should be considered in the development effort
- * ● 指导开发工作的设想和限制： 必须仔细地制定设想，尽管它会限制可能的产品概念范 围，但是它有助于项目管理。有关设想和限制的决策信息可以附加到任务书中。 Assumptions and constraints that guide the development effort
- * ● 利益相关者 (stakeholder): 确保开发流程中的细微问题均被考虑到的一种方法是，清楚地列出产品的所有利益相关者，也就是所有受产品成败影响的人群。利益相关者列表以末端使用者(最终的外部顾客)和做出产品购买决定的外部顾客开始，包括企业内 部与产品相关的人，如经销商、服务商和生产部门。利益相关者列表可以提醒团队考 虑被产品影响到的每个人的需求。¡ List all of the product’s stakeholders to ensure that many of the subtle development issues are addressed ¡ The list of stakeholders serves as a reminder for the team to consider the needs of everyone who will be influenced by the product
- ● 项目方向经常变动。l ·Inadequate coverage of target markets with competitive products l ·Poor timing of market introductions of products l ·Mismatches between aggregate development capacity and the number of projects pursued l ·Poor distribution of resources, with some projects overstaffed and others understaffed l ·Initiation and subsequent cancellation of illconceived projects l ·Frequent changes in the directions of projects
- ● 全新产品 (fundamentally new products): 这类项目涉及全新的产品或生产技术，并由此进入一个新的、不熟知的市场。这种项目本质上存在更大的风险，但是，公司的长期成功可能要依赖从这种重要的项目中获得的经验。New product or production technology for new and unfamiliar markets
新产品平台 (new product platform): 这类项目主要致力于在一个新的通用平台基础开发出一个新产品家族，这一新产品家族将进入相关市场和产品领域。New products for familiar markets and product categories
- ● 已有产品平台的衍生品 (derivatives of existing product platform): 这类项目是在已有产品平台上进行扩展，用一种或多种新产品更好地占有相关市场。Projects extend an existing product platform to better addresses familiar markets with one or two more products
- ● 对已有产品的改进 (incremental improvements to existing products): 这类项目只是增加或改进已有产品的特点，以使生产线跟上潮流和具有竞争力。May only involve adding or modifying some features of existing products to keep the product line current and competitive
Innovation is the process of creating something new that adds value to society. It can involve developing new products, services, processes, or business models. Innovation can be driven by a variety of factors, such as technological advances, changes in consumer preferences, or shifts in the competitive landscape.
There are many examples of innovative companies and products, such as:
- Apple: known for its innovative products, such as the iPhone and iPad.
- Tesla: known for its innovative electric vehicles and renewable energy solutions.
- Sinclair C5: an innovative electric vehicle developed in the 1980s that was ahead of its time.

产品架构可以描述为 :“ 将产品的功能元素排列成物理块以及块之间相互作用的方案”功能性——有助于整体绩效的单个操作和转换.物理–实现产品功能的零件、组件和子组件（通俗来讲，顺序是完成相应功能的零件component--->组件 chunks---->产品，产品架构就是以实体组件来实现产品的各功能单元，并使各组件相互作用的配置方案） Product Architecture can be described as: 1."the scheme by which the functional elements of the product are arranged into physical chunks and by which the chunks interact” 2.Functional – individual operations and transformations that contribute to its overall performance 3.Physical – parts, components and subassemblies that implement the product’s functions
- 目的：架构决策允许将这些物理模块的详细设计和测试分配给团队、个人和 /或供应商，以便不同部分的开发可以同时进行 Architectural decisions allow the detailed design and testing of these physical blocks to be assigned to teams, individuals, and/or suppliers, so that the development of different portions can be carried out simultaneously
- ◦模块化架构 modular architecture 特点：1.各个组件分别实现一个或多个功能 2.组件之间的关系是明确的，这种关系往往是实现一个产品功能的基础 ·Each chunk implements one or a few functions entirely. ·The interactions between chunks are well defined. ·Modular architecture has simplicity and reusability for a product family or platform. 理解：当每个功能都只被一个组件完成时，并且组件之间的配合十分完美时，这种架构允许在不改变的情况下只改变一组而不影响整体功能。也就是说各个组件可以单独设计
- ▪ 槽形模块架构 Slot-modular (the most common type) 每个接口都与于其它接口类型不同，产品中的组件不能互换 Each of the interfaces between chunks in a slot-modular architecture is of a different type from the others – therefore the various chunks in the product cannot be interchanged 例子：汽车上的收音机接口与速度仪、仪表盘的接口都不同
- ▪ 总线模型 Bus-modular 有一个通用总线，其他组件通过同类型的接口连接到这个总线上 There is a common bus to which the other chunks connect via the same type of interface 例子：轨道照明
- ▪ 组合型模块架构 Sectional-modular 所有接口都是同类型的，但是没有一个所有组件都与之相联的元件。组装是通过将同样的接口相连接而完成的 1.All interfaces are of the same type, there is no single element to which all the other chunks attach 2.The assembly is built up by connecting the chunks to each other via identical interfaces 例子：分体沙发
- ▪
- ▪ 产品架构的含义 你所做的关于产品架构的决定是有影响的 产品变化 模块化块允许对产品的一些孤立的功能元素进行修改，而不一定影响其他块的设计 改变的动机包括——升级、附加、适应、磨损、消耗、使用的灵活性、重复使用 There are implications to the decisions you make about product architecture ·Product change ·Modular chunks allow changes to be made to a few isolated functional elements of the product without necessarily affecting the design of other chunks ·Motives for change include – upgrades, add-ons, adaptation, wear, consumption, flexibility in use, reuse
- ▪ 积簇 多样性指的是企业在特定时期内根据市场需求所能生产的产品模型的范围 围绕模块化产品架构构建的产品可以更容易地变化，而不会给制造系统增加巨大的复杂性 例如移动电话手机设计、便携式音频 Product variety l Variety refers to the range of product models the firm can produce within a particular time period in response to market demand l Products built around modular product architectures can be more easily varied without adding tremendous complexity to the manufacturing system
- • ·几何集成与精确性Geometric integration and precision：把示意图中的几个单元集成到一个组件中，会使设计人员更好地 控制这几个单元的实体关系。这样，就能使出于同一组件，需要精确定位或紧密集成 的单元得到最好的设计。 l·Assigning elements to the same chunk allows a single individual or group to control the physical relationships among the elements l ·Elements requiring precise location or close geometric integration can often be best designed if they are part of the same chunk
- • ·功能共享Function sharing： 当一个单独的实体组件可以实现产品的若干功能单元时，这些功能单元最 好集成在一起 When a single physical component can implement several functional elements of the product, these functional elements are best clustered together l For example, an integrated control panel on a car
- • ·供应商能力Capabilities of vendors： 一个可靠的供应商可能具有与产品开发密切相关的某种能力。为了很好 地利用这种能力，开发人员会把那些供应商有制造经验的单元集成到同一个组件中， 并交给供应商生产 ·A trusted vendor may have specific capabilities related to a project l· To best take advantage of such capabilities a team may choose to cluster those elements about which the vendor has expertise into one chunk
- • ·设计或技术生产的相似性Similarity of design or production technology 当两个或更多的功能单元可能用同样的设计或生产技术完 成时，将这些元素集成到同一组件中将会使设计或生产更经济 When two or more functional elements are likely to be implemented using the same design and/or production technology, then incorporating these elements into the same chunk may allow for more economical design and/or production
- • ·集中修改Localisation of change 当开发人员预计某些单元可能要做大量的修改时，就有必要把该单元独立为 一个模块化的组件，这样对该组件的修改就不会影响到其他的组件。 When a team expects there to be a great deal of change in an element, it makes sense to isolate that element into its own modular chunk l In that way, any necessary changes to the element can be carried out without disrupting any of the other chunks
- • ·适合多样化Accommodating variety 示意图中元素的聚类应该有利于企业按照客户的具体要求来对产品做出 改动。打印机将在全世界电力标准不同的各个地区销售。所以，开发团队为与直流供 电有关的元素建立了单独的组件。 ·Elements should be clustered together to enable the firm to vary the product in ways that will have value for customers l ·Example – a power supply needs to handle different mains supplies in different countries
- • ·标准化Enabling standardisation 如果有一套元件在其他的产品中也可以使用，那么应该把它们集成到一个组件中。这样可以提高组件中各实体单元的生产质量。 l ·If a set of elements will be useful in other products, they should be clustered together into a single chunk l· This allows the physical elements of the chunk to be produced in higher quantities
- • ·关联的便利性：有些相互作用可以在长距离内方便地传递。
- ◦ 设计简略的几何结构Create a rough geometric layout
collapsed:: true
- 几何结构可以采用草图、计算机模型或物理模型(例如卡板纸或泡沫制成)在二维平面或者三维空间中进行设计。设计几何结构时，设计人员要考虑组件之间的几何关系是否可以实现，并确定组件间的基本空间关系。 A geometric layout can be created in 2 or 3 dimensions or as physical models l· an example can be found on a later slide ¡ ·Creating a geometric layout forces the team to consider l ·whether the geometric interfaces among the chunks are feasible and l ·to work out the basic dimensional relationships among the chunks
- ◦ 确定基本的和附属的相互作用关系Identify the fundamental and incidentalinteractions
- 首先是基本的相互作用关系 (fundamental interaction), 它与 示意图中连接各组件的那些线条相对应。例如， 一张纸从纸张托盘移动到打印装置中，因为 这种基本的相互作用关系是系统运行的基础，所以，在最早设计示意图时就应该计划好，并 要很好地加以理解。其次是附属的相互作用关系 (incidental interaction), 它是功能单元特定的 实体设置或组件之间具体的几何排列造成的。例如，纸张托盘中的传动器所引起的震动会干 扰打印墨盒在X 轴的精确定位。 It is most likely that a different person or group will be assigned to design each chunk ¡ Because the chunks interact with one another in both planned and unintended ways, these different groups will have to coordinate their activities and exchange information ¡ To manage this coordination process better, the team should identify the known interactions between chunks during the system-level design phase There are two categories of interaction l Fundamental ¡ Those which correspond to the lines on the schematic that connect the chunks to one another ¡ These are the fundamental interactions of the systems operation l Incidental ¡ Those that arise because of l the particular physical implementation of functional elements, or l because of the geometric arrangement of the chunks ¡ An incidental interaction graph is used to document this type of interaction, see next slide
- The output of Phase 3 is the control documentation for the product¡ ·The control documentation is:l ·The drawings or computer files describing the geometry of each part to be made and its production toolingl ·The process descriptions for the fabrication and assembly of the productl· The specifications of the parts to be purchased
- 什么是原型 :-> “依据一个或多个方面的兴趣而得到的产品的近似品”(an approximation of the product along one or more dimensions of interest)a smallscale modeli.e.¡ ·Industrial designers produce prototypes of their concepts, such as models¡ ·Engineers prototype a design¡ ·Software developers write prototypeprogramsPrototyping is the process of developing such an approximation of the product
- ◦ Beta原型在内部进行了广泛的评估，并且通常由客户在他们自己的使用环境中进行测试测试原型的目标通常是回答关于性能和可靠性的问题，以便为最终产品确定必要的工程更改Beta prototypes are extensively evaluated internallyand are also typically tested by customers in their own use environment¡ The goal for the beta prototypes is usually to answer questions about performance and reliability in order to identify necessary engineering changes for the final product
- 试产原型 (preproduction prototype)是整个公司生产的第一批产品生产过程Are the first products produced by the entire production process

- 什么是原型化（prototyping）:-> 原型化是快速组装工作模型 (原型 )的过程，目的是测试设计的各个方面，阐明想法或功能，并收集早期用户反馈。Prototyping is the process of quickly putting togethera working model (a prototype) in order to testvarious aspects of a design, illustrate ideas or featuresand gather early user feedback
- 学习(learning):原型通常用于回答“它能否工作?”和“它满足消费者需求的程度如何?”。 当回答这类问题时，原型就作为学习的工具。Answering questions about performance or feasibility , such as“Will it work?”“How well does it meet the customer needs?”
- 沟通（communication）沟通 (communication): 原型加强了开发团队与高层管理者、供应商、合作人、开发团队 扩展成员、消费者及投资者间的沟通。·Demonstration of a product to get feedbackfrom all stakeholders·A physical, tactile, 3D representation of aproduct is much easier to understand than averbal description or even a sketch of aproduct例子：以一个可见的、能 触知的三维图形来表现一个产品，比语言草图描述更易理解。在PackBot 概念开发中，通过利 用“可视、可感知”的原型，设计工程师、经理、供应商和顾客间的沟通得到加强。新的消 费者经常对PackBot 底盘过于狭小不满意，然而，实物模型清晰地展示了有限的空间。
- 集成 integration原型用于确保产品的子系统及组件能如预期的一样协同工作。综合化的实体原型在产品开发项目中作为集成工具最为有效，因为它们要求零件、各部件间协调，并与零件组成一个产品。要做出这样的原型，需产品开 发团队成员相互协作。如果产品任何组件的组合妨碍了 产品的整体功能，这一 问题只能在综合化的实体原型中 通过集成来检测。·Prototypes are used to ensure that componentsand subsystems of the product work together as expectedl ·Comprehensive physical prototypes are the most effective as integration tools in product development projects because they require the assembly and physical interconnection of all of the parts and subassemblies that make up a productl ·The integration of the prototype forces coordination between different members of the product development teaml ·For example: alpha or beta test models
- 里程碑 milestones尤其是在产品开发的后期，原型用于验证产品在功能上已达到期望水 平。里程碑原型提供可触知的目标，表明了进展情况，并用来加强进度安排。Provide goals for the development team’sschedule· Milestone prototypes are defined in the product development project plan这种原型的数量和它们的时间是整个开发计划的关键要素之一作为一个基本案例，开发团队应该考虑使用 alpha、 beta和预生产原型作为里程碑The number of such prototypes and their timingis one of the key elements of the overall development planl ·As a base case, the development team should consider using alpha, beta and pre-production prototypes as milestones¡ e.g. first testable hardware
- Physical prototypes are :-> tangible artifacts created to approximate the product ¡ ·Aspects of the product of interest to the development team are actually built into an artifact for testing and experimentation ¡· Examples of physical prototypes include l ·models which look and feel like the product l ·proof-of-concept prototypes used to test an idea quickly l· experimental hardware used to validate the functionality of a product例子：一个木制的玩具模型
- Analytical prototypes :-> represent the product in a non-tangible, usually mathematical, manner¡ ·Interesting aspects of the product are analysed, rather than built例子：数学分析、建模
- ◦ 综合 (comprehensive) :-> 能完成产品的绝大多数属性。·Comprehensive prototypes implement most, if not all, of the attributes of a product¡ ·A comprehensive prototype corresponds closely to the everyday use of the work prototype – i.e. it is a full-scale, fully operational version of the product例子：β原型，用来给测试功能
- ◦ 专一化原型 (focused prototype) :-> 只履行(完成)产品的某个或某些属性。一个普遍的做法是用两个或多个专一化原型一起探查一个产品的所有性能。这些 原型包括外观 (looks-like)原型和工作原理 (works-like)原型。通过制造两个分离的专一化原型，开发团队可以比制造一个综合化原型更早地解决问题。·Focused prototypes implement one, or a few, of the attributes of a product¡· Examples of focused prototypes include foam models toexplore the form of a product and wire wrapped circuitboards to investigate the electronic performance ofproduct design¡ ·A common practice is to use two or more focused prototypes together to investigate the overallperformance of a product·By building two separate focused prototypes, the teammay be able to answer its questions much earlier than ifit had to create one comprehensive prototype
- Analytical prototypes are in general moreflexible than physical prototypes¡ ·Physical prototypes are required to detectunanticipated phenomena¡ ·Prototypes may reduce the risk of costlyiterations¡ ·Prototypes may expedite other developmentsteps¡ ·A prototype may restructure task dependencies示例 :在零件设计 -模具设计 -成型流程中添加原型制作步骤 原型可以重构任务依赖关系
- 界定原型的目的·define the purpose of the prototype原型的四个目的是：学习、沟通、集成和里程碑。在界定原型目的的过程中，开发团队列出具体的学习与沟通需求，也列出了集成需求以及这一原型是否作为整个产品开发项目中的一个里程碑。l ·The team lists its specific learning andcommunication needsl ·Team members also¡ ·list any integration needs¡· decide whether or not the prototype isintended to be one of the major milestonesof the overall product development project例子：车轮原型的目的是决定车轮的抗震性能和安全性能。虽然学习原型的目的专注于性能，但开发团队还是要考虑材料的制造成本，其中，很多材料是不可铸造的，必须机加。
- 建立原型的近似水平Establish the level of approximation ofthe prototype对原型进行计划需要确定原型与最终产品的相似程度。开发团队应考虑一个实体化原型是否必需，或一个解析化原型能否最好地满足它的要求。在大多数情况下，最好的原型是那个满足步骤1所设定目的的最简单原型The degree to which the final product will be approximated in the prototype must be defined l The team should consider whether a physical prototype is necessary or whether ananalytical prototype would best meet its needs例子:对于车轮原型，团队要根据冲击效果来决定车轮的材料和几何形状。然而，车轮的其他 方面可能被忽视，包括生产方法(铸模或者机加)、驾驶系统的附件和铁轨带、车轮的颜色和 整体造型等。团队中一名成员先前就研究了轮辐弯曲效果的解析化原型，她认为原型的物理 特征对于确认她的分析很有必要。她发现抗震效果和车轮力量之间存在一个基本的取舍关系， 因为抗震需要轮辐柔韧，而车轮力量需要车轮尺寸更大。因此，团队使用解析型原型和物理原型来决定轮辐的尺寸。
- 制定实验大纲Outline an experimental plan大多数情况下，在产品开发中使用原型可以看成一个实验。好的实验有助于从原型化活动 中获取最大价值。实验计划包括确认各种实验变量、测试草案、进行哪些测试的指示以及分 析最终数据的计划。当必须探索许多变量时，有效的实验设计将极大地加快这一进程。·The use of a prototype in product development can be thought of as an experimentl ·Good experimental practice helps to make sure that you get the maximum value from the prototyping activity例子：对于车轮原型测试，团队决定只改变轮辐的材料和网的几何形状。根据解析化原型，团队 选择了两种样式的轮辐，每种轮辐又选择了6种材料，总共进行了12次实验。团队设计了一 个结实的平台，每个车轮被安装后由不同的高度落入平台，通过观察平台的受重就可以测试 车轮传递给 PackBot的冲击力。在完成所有的实验后，相关人员会观察车轮落下的损伤，包括 裂纹和塑性变形，然后再提高一个高度进行测试。这些测试的结果不仅可以用来选择最好的轮辐几何和材料，而且可以改善车轮的物理解析化原型。
- 制定采购、建造和测试的时间表Create a schedule for procurement,construction and testing因为建造和测试一个原型可以看作整体开发项目内的一个子项目，因此，开发团队会从制 定原型化活动计划中获益。对于一个原型计划，有三个日期特别重要：第一，部件可装配的日期(这一 日期有时被称为“部件水桶 (bucket of part)”日期);第二，原型进行首次测试的日 期(这一 日期有时被称为“冒烟实验 (smoke test)”日期，因为在这天，开发团队将首次在产品中通电并在电器系统中“寻找烟”);第三，完成测试并产生最终结果的日期。Three dates are particularly important in defining a prototyping effort¡ ·The team defines when the parts will be ready to assemble¡ ·The team defines the date when the prototype will first be tested¡ ·The team defines the date when it expects to have completed testing and produced the final results

Relationship between a vulnerability and a threat脆弱性和威胁之间的关系
An organization does not have sufficient controls to prevent an employee from deleting critical computer files (lack of controls – vulnerability). An employee could delete files by mistake (employee – source of threat) (deleting critical files – threat). If the files are deleted, successful exploit of the vulnerability has taken place. If the file is not recoverable, the incident harms the organizations and its security. Availability is compromised.
