Object Oriented Programming

1. Software specification, where customers and engineers define the software that is to be produced and the constraints on its operation.

2. Software development, where the software is designed and programmed.

3. Software validation, where the software is checked to ensure that it is what the customer requires.

4. Software evolution, where the software is modified to reflect changing customer and market requirements.

Software process activities
Software specification - example
Software development
@PostMapping(value="/aliApplyAV", produces="application/json")
public String aliApplyAV (String enApplyAV) {
return avService.decryptAndSaveAvRequest(enApplyAV);
}
@PostMapping(value="/aliCancelAV", produces="application/json")
public String aliCancelAV (@RequestBody String enCancelAV) {
// Receive cancel request 4.3
return avService.decryptAndSaveAvRequest(enCancelAV);
}

Software validation

• In some form, these activities are part of all software processes.
• In practice, of course, they are complex activities in themselves and include sub-activities such as requirements validation, architectural design, unit testing, etc.
• There are also supporting process activities such as documentation and software configuration management.

Software Processes

• There is no ideal process and most organizations have developed their own software development processes.
• Processes have evolved to take advantage of the capabilities of the people in an organization and the specific characteristics of the systems that are being developed.
• Sometimes, software processes are categorized as either plan-driven (planned in advance and progress is measured against this plan) or agile processes (planning is incremental and it is easier to change)
