Project Risk Management Project risk is an uncertain event or condition that, when it occurs, has a positive or negative impact on the project's objectives, when an event, activity, or project has a loss or income associated with it, it involves a certain probability or uncertainty and involves a certain choice, which is called risk, and each of the above three is a necessary condition for the definition of risk. An event with uncertainty is not neces

pictures together, the original image file is separate. After merging, you can clearly see the aspects that each phase contains. Here are my own analysis and notes. 　　Strategy User needs and development objectives. What the user needs, what is the goal of building this app/web, these are the foundation of the entire project at the bottom, but also the basis of all origins. On the basis of instability, the more the problem will be more and more, al

field of philosophy, methods and strategies. Are we missing something important? Is it that we lack a deeper thinking? Even if we lose our way? Thinking alone is not enough. In a great deal of literature on user research that I've studied, most of them discuss the specific methods of user research and how to use them, which is a hodgepodge, including on-site observation, ethnography (participatory observation), shadow following, in-depth interviews, focus groups, questionnaires, diary method

management is obvious, it is recommended to have time to achieve such tracking. 1.1.1.1 purpose: To ensure that all the user's original requirements are met. 1.1.1.2 Benefits: Developers are able to pinpoint the underlying requirements when they are implemented. can provide firsthand evidence of the need for software requirements. It is easy to find contradictions and ambiguities between needs. 1.1.1.2 specific means: in the sixth chapter of the requirements analysis and modeling best practice

(motivation) at work, and motivation depends on the target, so the end will usually fall to the user goals. By "goal" to divide the user group, and then to understand the same target user demographic data, which is the opposite of the basic user research, and precisely because of this, the two are complementary to each other.From product user research and basic user studies, Angela, published in user research I. Determination of the purpose of researchDetermining the purpose of research is th

requirements Define the software features that a developer must implement to enable the user to complete their tasks to meet the business requirements. Non-functional requirement is the user's expectation to the good operation of the system, including the quality attributes such as ease of use, reaction speed, fault tolerance, robustness and so on. The demand acquisition is to obtain the system user's demand according to the system business demand, then obtains the system function demand and t

The experience of testing--------------------------------------------------------------------------------A considerable part of software engineering is about software testing: 1. Scope of test concept Broadly speaking, testing refers to all the inspection, review and validation activities within the SOFTWARE PRODUCT life cycle. such as: Design Review, System testing. In the narrow sense, testing is the inspection and evaluation of software PRODUCT quality. On the one hand, it checks the quality

project manager meets the project objectives, determines time, cost, scope, and quality, which reflect the scope of the project. In short, the project manager should be in a certain amount of time, cost, quality to complete the project requirements of the task. U Project plan elements the project manager needs to develop a project plan, and for the entry-level project manager, they may not know how to make a project plan. The following are common el

Objectives of database three paradigms: 1. reduce data redundancy 2. eliminate exceptions (insert, delete, update) 3. to make data organizations more harmonious, the first paradigm (1NF): Non-duplicate columns the so-called first paradigm (1NF) means that each column of the database table is an inseparable basic data item. For example, an object cannot have multiple or duplicate attributes. Objectives of da
