Software feasibility study and Project Development Plan

I,Feasibility Study

ØTask

First, we need to conduct a brief analysis and research, preliminarily determine the project scale and objectives, determine project constraints and restrictions, and list them clearly.

Then, the analyst analyzes the summary of requirements, abstracts the logical structure of the project, and establishes a logical model. From the logic model penalty and compressed design, several main solutions are explored, and the feasibility of each solution should be studied. The feasibility of each solution can be analyzed from three aspects:

1) Technical Feasibility

2) economic feasibility

3) social feasibility

ØProcedure

1) determine the project scale and objectives

2) study the Running System

3) create a new high-level logical model for the System

4) Export and evaluate various solutions

5) recommended feasible solutions

6) prepare a feasibility study report

II,System flowchart

A system flow chart is a traditional tool used to depict physical systems. It uses graphical symbols to represent various elements in the system, such as manual processing, data processing, databases, files, and devices. It expresses the information flow between elements in the system. The symbols of the system flowchart are as follows:

 

 

 

III,Cost-benefit analysis

Cost-benefit analysis aims to evaluate the feasibility of developing a new software project economically.

After the cost estimation, the project development cost is obtained, which is the project investment. After the project is developed, the corresponding benefits should be obtained. How many benefits are cost-effective? This requires consideration of the time value of the currency. The interest rate is usually used to indicate the time value of the currency.

Set the annual interest rate to I, for example, P yuan. The amount of money available after n years is F yuan. If compound interest is not included, F = P * (1 + n * I)

F is the value of P yuan after n years. Otherwise, if you can earn RMB f in n years, the current value of the money is: P = F/(1 + n * I)

Payback period: the time required to make the cumulative economic benefits equal to the initial investment cost.

Net income: the difference between the cumulative economic benefits (equivalent to the current value) and investment in the entire life cycle.

Benefits are divided into tangible and intangible benefits. Tangible benefits can be measured by monetary indicators such as time value, payback period, and net income. intangible benefits are measured mainly in terms of nature and mind, and it is difficult to compare the amount directly.

 

IV,Project development plan

A project development plan is a management document with the following content:

1) Project Overview

2) Implementation Plan

3) personnel organization and division of labor

4) delivery period
