Definition of demand?

Question 1: How to understand the definition of "demand" Demand is divided into three levels:

1. Business requirements mean the goal of the organization or senior management, that is, to achieve the goal of this project/product. It usually includes the prospect and general scope of the project.

Second, user needs, as the name implies, are the things and tasks that users do, as well as their expectations for quality attributes such as performance and applicability. For example, people from different departments approve a document; After using it online, you should reserve a book in the online bookstore. It can be expressed by use case diagram.

Third, functional requirements, that is, what functions should be implemented to meet the needs of users. For example, develop a shopping cart to realize the function of buying books online: first, you can preview the bibliography, select your favorite books and put them in the shopping cart, and click the settlement button to jump to the settlement interface.

From abstract to concrete, business requirements guide user requirements, and user requirements determine functional requirements; Functional requirements are to meet the needs of users and achieve the high-level goal of "business requirements".

In addition, requirements also include non-functional requirements, including descriptions of performance indicators and quality attributes. Quality attributes include usability, portability, integrity, efficiency and robustness.

Question 2: Definition of demand In fact, the first concept is the definition of demand.

The second is the definition of demand.

Of course, the discussion of demand should cover all possible price levels. The price of the same commodity is different in different cities, but we must count the total demand of the commodity.

Question 3: What's the difference between demand and demand? Changes in demand refer to changes caused by factors other than commodity prices, such as consumption habits and wage changes. , showing the parallel movement of the demand curve on the map; The change of demand refers to the change caused by the price change of commercial banks, which shows the relationship between different points on a demand curve.

Question 4: What is the definition of workplace and what is the definition of workplace needs? 20 points in the workplace: politics and economy are inseparable in society. In the workplace, politics and personal ability are also inseparable. The elites in the workplace are all capable people and understand politics. Personal ability is manifested in time control ability, knowledge level, problem-solving ability on the spot, and political ability in the workplace is manifested in the ability to judge one's own environment.

Politics and economy in society are inseparable. In the workplace, politics and personal ability are also inseparable. The elites in the workplace are all capable people and understand politics. Personal ability is manifested in time control ability, knowledge level and problem-solving ability on the spot, while workplace political ability is manifested in the ability to judge one's own environment and create favorable conditions for oneself.

The so-called occupational demand refers to a person's desire and desire for a certain occupation. This longing and desire has become the source of a person's enthusiasm for professional behavior. Since the emergence of social division of labor, there has been a professional demand. The original professional needs are actually just a simple survival needs of a person. With the development of society, occupations are constantly differentiated, and new contents are constantly given to the demands of occupations. Occupations are varied, and people's needs for occupations are different.

Question 5: What is the definition of requirement analysis? In software engineering, requirements analysis refers to all the work to be done when describing the purpose, scope, definition and function of a new computer system when establishing a new computer system or changing an existing system. Requirements analysis is a key process in software engineering. In this process, system analysts and software engineers determine the needs of customers. Only after they have determined their own needs can they analyze and seek the solution of the new system.

Question 6: What are the software requirements and functional requirements? Our software products or projects have three levels and three aspects. First, let's look at three levels of requirements. Software requirements include three different levels of business requirements, user requirements and functional requirements. Business requirements represent the high-level goals of an organization or a customer. Business needs usually come from project investors, customers who buy products, managers of actual users, marketing departments or product planning departments. Business requirements describe why an organization should develop a system, that is, what the organization hopes to achieve. Use a vision and scope document to record business requirements, which is sometimes called a project diagram or a market demand document. User requirements describe the user's goals or tasks that the user requires the system to complete. Use cases, scenario descriptions and event DD response tables are all effective ways to express users' needs. In other words, user requirements describe what users can do with the system. Functional requirements specify the software functions that developers must implement in products, and users use these functions to complete tasks and meet business requirements. Functional requirements are sometimes called behavioral requirements, because it is customary to describe them with "should": "The system should send an email to inform the user that it has accepted its reservation". Functional requirement description is what developers need to realize. Note: User requirements do not always translate into functional requirements. Product function, the so-called characteristics, refers to a set of logically related functional requirements, providing users with certain functions to meet business goals. For commercial software, function is a set of requirements that can be recognized by customers and help them decide whether to buy or not, that is, the parts marked with bullets in the product manual. The product features that customers want are not exactly the same as the task-related needs of users. A feature can contain multiple use cases, and each use case needs to implement multiple functional requirements so that users can perform a certain task. System requirements are used to describe the top-level requirements of products (i.e. systems) that contain multiple subsystems. A system can contain only software systems, or both software and hardware subsystems. People can also be a part of the system, so some system functions may be undertaken by people. Business rules include enterprise policies, regulations, industry standards, accounting standards and calculation methods. Business plans themselves are not software requirements, because they do not belong to the scope of any particular software system. However, business rules often limit who can execute certain use cases or stipulate that the system must implement certain functions in order to comply with the relevant rules. Sometimes, certain quality attributes in a function (realized by the function) also come from business rules. So when we trace back to some functional requirements, we will find that its source is a specific business rule. Functional requirements are recorded in the Software Requirements Specification (SRS). SRS completely describes the expected characteristics of the software system. SRS We usually regard it as a file. In fact, SRS can also be a database or spreadsheet containing demand information. Or information stored in business requirement management tools; For small projects, it may even be a stack of index cards. SRS is used for development, testing, quality assurance, project management and other related project functions. In addition, for the demand level, we have other sub-methods: organizational level demand->; Business requirements->; User demand-> Functional requirements (sometimes called behavioral requirements). Organization-level requirements: usually represent the vision and goals of the organization. For large companies, it is generally obtained through senior consultants and consulting companies, and the presentation method is consulting reports. For example, in ITSM or enterprise informatization. Typical organizational needs include: reducing costs, reducing inventory costs, enhancing the value of enterprise IT service departments, adopting ISO20000, improving IT service efficiency, and improving employee satisfaction. Business requirements: the requirements of each business process and business unit to complete the mission and realize the organizational vision. Business needs are subordinate to organizational needs. User demand: user-level demand refers to business-level demand, the demand of each position ... >>

Question 7: What is the definition of demand theory in economics? Demand: the number of products that all residents in a market are willing to buy. This definition includes four meanings: 1. Refers to the purchase quantity that can be paid. 2. It refers to the purchase quantity within a period of time. 3. The number of "willing" purchases may be different from the transaction volume. 4. It refers to the quantity you are willing to buy at a certain price. Reference: jjxj/articles/12431.

Question 8: Briefly describe the definition of drug demand. The content of drug market research is very extensive. To sum up, it mainly includes four aspects, namely, drug market environment research, market demand research, competitor research and customer (beneficiary) research.

(A) the drug market environment research

The investigation of drug market environment mainly investigates political environment, economic environment, cultural environment and geographical environment. Market environment survey is mainly used to explore new markets.

Political environment.

The political environment includes departments related to drug production and business activities and their responsible persons and key personnel. The departments and units that the company has to deal with when exploring new markets generally include the Trademark Office of the Industrial and Commercial Bureau, the Advertising Department, the Health Bureau, the Drug Control Department, the Medical Technology Bureau, the Food Supervision Bureau, the Tax Bureau, the Environmental Sanitation Urban Management Brigade, the Party newspaper, the Evening News, the TV newspaper, the bus company, the tram company, the taxi company, the cable TV station, the Youxian TV station and various professional TV stations. Through investigation, we can get to know the backbone personnel of all departments and units. Correctly implement the strategy of shaking hands at both ends and embracing in the middle.

The political environment also includes the implementation of local medical policies, drug advertising policies and urban management policies. The investigation of these policies is mainly to prepare for advertising and developing hospitals.

2. Economic environment

Crowded environment mainly refers to the level of economic development. Gross domestic product can be used to measure the local economic level. Through the investigation, we can divide the economic development level of different areas in the investigation area, so as to give priority to opening the market breakthrough in the local richer areas.

The economic environment also includes the local price level. You can find wholesalers and retail suppliers to investigate the wholesale price and retail price of related drugs respectively, and understand the purchasing power level through price adjustment to prepare for the formulation of marketing price strategy.

The economic environment also includes the industrial structure. By investigating the industrial structure, we can understand the local development and the concentrated areas of high-profit and high-efficiency industries. We can also analyze the quality structure and professional characteristics of local residents through industrial structure, thus helping to determine the focus of marketing strategy. In marketing activities, we should consider the characteristics of the main industrial personnel in the investigated area.

3. Cultural environment

Cultural environment includes cultural level, national characteristics and customs. Through the investigation of cultural levels, we can adopt different marketing strategies for different cultural levels of consumer groups. For ethnic minority areas, finding out ethnic characteristics, especially festivals, is conducive to grasping the characteristics and holiday opportunities for marketing planning. Carry out free clinic, charity sale and other activities, and respect local customs and habits in drug marketing.

(B) Market demand research

(1) Market situation (scale, supply and demand, etc. ), including the market demand and sales volume of existing drugs, whether the supply exceeds demand, the market life cycle stage of drugs, etc.

(2) The demand of a drug in different market segments, and the saturation point and potential capacity of each market segment.

(3) the market share of drugs in this enterprise, and which market segments are most beneficial to the enterprise.

(4) Competition evaluation (direct competition and indirect competition), including the position and role, advantages and disadvantages of competitors. How to develop strengths and avoid weaknesses, and give full play to the advantages of this enterprise.

Question 9: The definition of original requirement The word original requirement is rarely mentioned now, but it is indeed an important name in the process of requirement development and management. Simply put, the original demand refers to the problem that customers hope to solve through a product or service.

To give an inappropriate example, for example, a customer came panting and said, "Come on, man, have an iced coke." Do you want to run 10 km and buy it back? I'm sorry I didn't sell it. If you can understand that he is thirsty and boiled water can solve the problem, things will be simple ... "thirst" is the source and "thirst-quenching drink" is his real need; "Coke" or "boiled water" is the product demand and the solution you provide.
