Soft Guide Drawing summary--software plan

This time we're talking about software planning, which is the planning phase of the software lifecycle, which is the initial phase.

The first job of a software plan is the problem definition, which includes two aspects, namely content and steps.

The next task of defining the problem is the feasibility study, which includes the content steps of the study and the flow chart of the feasibility study system. The feasibility research contents from the big aspect including economy, technology, operation, Law, time these 5 aspects, to our technical personnel to say the technical feasibility is we need to concern.

Down is the software program, which includes 3 aspects of software scope, software scope, and software plan. The software scope includes the SOFTWARE function scale, the software ability to the hardware requirement, the interface interface nature and the complexity and so on, but the environmental resources including is more extensive, such as human resources, hard software resources, schedule, resource description and so on.

Then is the software price evaluation, the evaluation method has four, respectively is the parameterization algorithm, the code line estimation, the task decomposition method, the automatic estimation cost method.

Finally, we analyze cost and benefit, including cost estimation, cost-benefit analysis and some concepts.
