Thank you for the opportunity to help you with your question!

Stages of software development:

  1. Requirement gathering and analysis

Here all parties involved come together  and gather all relevant information about the current system and what improvements or new feature should be introduced. They then make a decision based on the analysis on whether to develop a new one or not.

2. Design

After agreeing on whether to develop a new system, the entities led by the system analyst transform the desired  system in to a drawn structure showing how the new system will work

3. Implementation or coding

When the design has been done, programmers swing in to action and implement the design by developing a procedures and modules to solve a certain problem

4. Testing

When the system has been designed and a software developed, th new system is tested with both live and dummy data to establish whether it has any bugs or has some features missing. At this stage the system is tested for: logical errors, syntax and semantic errors.

5. Deployment

Deployment is the stage where the system is implemented. At this stage there is a  transition from the old system to a new system.

6. Maintenance.

This stage involves routine checks to the system to ensure that serves the purpose it was intended for.

The most time consuming stage to me is the design stage. It is at this stage where every activity of the system is defined and an algorithm developed. Coming up with algorithms takes relatively longer time as compared to others.

The most important stage is the  initial stage where all requirements are gathered and a decision is made on whether there is need for a new system or not.


Please let me know if you need any clarification. I'm always happy to answer your questions.
