Software project Management

The object of software project management is software engineering project. Its scope covers the entire software engineering process. In order to make software project development successful, the key issue is to have a good understanding of the scope of the software project, the possible risks, the need for resources (people, hardware/software), the tasks to be achieved, the milestones that have been spent, the cost of work (costs), schedule, etc. This kind of management should begin before the technical work begins, and continues in the process of software from concept to implementation, and terminates only at the end of the engineering process. Start a software project to identify the objectives and scope of the project, consider candidate solutions, and demonstrate technical and managerial requirements.

The measurement work is done to understand the technical process of product development and the product itself. Its role is to effectively quantify the management.

Scale-oriented metrics:

is a direct measure of the software and software development process, you can create a scale-oriented data table to record certain information about the project.

Example: scale-oriented data tables

You can calculate an average for all items based on the data table:

Productivity =KLOC/PM (Person month)

Mass = number of errors/kloc

Cost = Meta/loc

Document = Document Page/kloc

Feature-oriented metrics:

Functional-oriented software metrics are an indirect measure of software and software development processes. This metric focuses on the "functionality" and "practicality" of the program, rather than on the LOC count.

Example: feature-oriented data tables

function point calculation: 1, user input number 2, user output number 3, user query number 4, number of files 5, external interface number

Compute function Points:

Total number of fp= * (0.65+0.01*sum (Fi))

Total number: Is the sum of all weighted counts

Fi (I=1-14) is a complex correction, and they should be determined by answering the following questions individually

Value of fi 0-5

0: No influence 1: Accidental 2: Moderate 3: Normal 4: Important 5: Extremely important

SUM (Fi) is the SUM function

Complexity Calibration Positive fi

Once the function points are calculated, the productivity, quality and other properties of the software can be measured in the same way as Loc.

Productivity =KLOC/PM (Person month)

Mass = number of errors/kloc

Cost = Meta/loc

Document = Document Page/kloc
