This phase entails writing the code, including algorithms, functions, and classes that bring the software to life.

Stage 5. Testing

To guarantee software quality, the development team conducts a thorough testing phase.

Various testing types are employed to assess the system performance, including unit testing, integration testing, system testing, and user acceptance testing.

Stage 6. Deployment

With testing successfully completed, the software is made accessible to users.

This step may involve making the software available for download or deploying it to a production environment.

Stage 7. Maintenance

Following deployment, the team remains committed to enhancing and sustaining the software’s performance.

This includes bug fixes, incorporation of new features, and updates to bolster security.

Software Development Methodologies

There are various software development methodologies to choose from, each with its own approach:

  • Agile methodology – It divides projects into small increments called sprints. The agile model is well-known for its flexibility and customer-centric approach.
  • Waterfall methodology – This traditional method follows a linear sequence and is suitable for predictable, regulated industries but may lack adaptability.
  • Hybrid methodology – Combining different approaches, hybrids offer flexibility tailored to specific project needs but may require more expertise.
  • DevOps methodology – It integrates development and operations teams to streamline the software development lifecycle with automation and continuous improvement.
  • Scrum methodology – A popular type of agile framework, this method emphasizes collaboration, transparency, and adaptability, making it ideal for projects with evolving requirements.

Choosing the Right Software Methodology

To choose the right software methodology for your project, ask yourself the following questions:

  • Business requirements: What are the specific needs that your software needs to meet?
  • Software development goals and objectives: What do you want to achieve with your software?
  • Project timeline: How much time do you have to develop your software?
  • Organization’s risk tolerance: How much risk are you willing to take on?
  • Budget and cost-control requirements: How much money do you have to spend on developing your software?

Let’s say you’re creating a financial trading system for a big bank with clear requirements and a lengthy schedule.

In this case, it’s best to choose the Waterfall Model for its predictability and risk reduction.
