Demand analysis is a requirement engineering activity which is used to solve the need of obtaining information and developing the software system solution which needs to be established. Demand analysis occupies an important position in demand engineering. In the process of demand analysis, we need to constantly collate

We said that, unlike heavy-duty methods, which focus on planning, processes, and intermediate products, agile methods focus more on people and communication. People and communication are always the first, and planning, processes, and intermediate products are just a means to ensure communication and achieve goals. This does not mean that the Plan, process, and intermediate product are not important, but they cannot put the cart before the horse.Note: We define intermediate products as documents,

1. What is a sample on demand? When learning or evaluating technology, architecture, or design techniques, software developers will tell you that there is nothing in development practice that can be compared to the value of a working example for a project that successfully employs the above elements. To facilitate rapid developer learning, GENUITEC provides sample on-demand, providing software developers wi

First, preface About the personnel file system, the system itself is not difficult to implement the function, but because of the logic of its data information is very problematic, so that the logical change of the system, here is a big reason in the customer's needs change and business needs are not clear.

The meaning of the demand scenarioIn the traditional

this step, we need to classify the demand items. Each requirement should have its importance, priority, and remarks (success criteria, etc ). The criteria for determining each requirement attribute are weighed based on the commercial value and design criteria analyzed above. Finally, we will classify and summarize each requirement item, review both parties in the requirement list, and confirm the requirement scope and requirements. 4. In the subseque

the report content is accurate and complete. A high-quality Requirement Analysis Report helps developers develop products they really need. 4. Explanation of requirements Analysts may use a variety of charts as a supplement to the text requirement analysis report, because the work chart can clearly describe some aspects of system behavior, therefore, various charts in the report have extremely high value. Although they are not easy to understand, customers may not be familiar with them, therefo

What startups require is a fast iteration of the product to find the precise user and start making business sense, which is a very simple and easy-to-understand process (in fact, much more complex), so the first step is how the product manager will respond to demand changes and technology development in the iterative product process.

Common Software Requirement analysis methods include data flow-oriented structured analysis, data structure-oriented Jackson, object-oriented,
