Software Development Life Cycle Explained by a Project Manager

Entrusting your software development to another company may be stressful. I totally get that; it’s your beloved idea, and you want to put it in good hands.

It may be especially nerve-racking if you like to manage every aspect of your business. However, you can’t be an all-arounder, and it’s good to entrust your product to specialists.

Between having an idea and developing a fully-functioning software product, there’s a long way ahead. Thankfully, if you like to be in charge, there are some steps and milestones that you can follow.

These steps and achievements are a part of the Software Development Life Cycle. And what’s that? Follow me to find out.

What is a Software Development Life Cycle (SDLC)?

SDLC or Software Development Life Cycle is, in general terms, a process used by the software industry to design, develop, and test high-quality software.

The idea behind the software development life cycle is to lower the cost of software development, at the same time improving quality and shortening production time. It’s a continuous process. It starts from the moment when the project is launched, and it lasts until the last days, including the development process, as well as fixes and improvements.

SDLC consists of several distinct stages, including planning, design, building, testing, and deployment.

Why do IT projects need SDLC? It’s the best way to plan the development process and meet the demands of a business, as well as users.

Stages and SDLC Best Practices

Identify the Requirements

“What do we need?”

The first step of SDLC is establishing requirements and discussing the needs. It puts you, the client, in the spotlight. It’s your time to consult all the necessary specialists in your company and create a coherent vision of your future product.

It’s crucial to focus on the potential users’ needs and identify key business requirements and expectations. I advise you to conduct extensive customer research and analysis, then use the acquired information to create a list of desirable features.

As for presenting your ideas to the software development team, make sure to present them clearly and understandably. Leave no detail behind! If you need some additional help, you can think about consulting business analysts. However, never underestimate the importance of your insights, and don’t hesitate to share your business knowledge!

Design

“How to get what we need?”

The next stage of SDLC is the design phase. It’s the time to translate your requirements and needs into software design. It involves designing the entire system, as well as its elements.

Considered the most important in SDLC, the design phase helps in specifying hardware and system requirements, as well as defining overall system architecture. The system design specifications serve as input for the next phase of the model.

Feel a little bit marginalised? Don’t worry! You can actively follow your team’s actions and provide additional advice and details if needed.

Build

“Let’s develop what we need.”

The third phase of SDLC is about delivering the product, based on your requirements and the design.

Using the design document, programmers code respective modules. The coding tasks are divided between the team members according to their area of specialisation. The result of this phase is a working software product and a Source Code Document.

You can’t actively influence the coding phase, and you must entrust the developers. However, don’t worry, if you chose the right people you can expect incredible results.

Code Test

“Did we get what we need?”

It’s the moment of truth. It’s time to check if all the requirements have been met and if the software runs smoothly.

Testers‘ job is to search for defects within the system. They verify if the product behaves as expected and in compliance with what was documented in the requirements analysis phase.

They repeat the cycle until all requirements have been tested and all the defects have been fixed and the software is ready to be shipped to the market.

It’s an extremely important stage, as it indicates if your product meets your initial requirements.

Never underestimate the power of testing, as it can prevent future problems and ensure the highest quality.

Software Deployment

“It’s time to start using what we got.”

In this phase, the product is finally delivered to the public. Once it has been fully tested and has no high priority issues, it’s time to present it to the users.

The support team collects feedback from the first users, and if any bugs come up, the development team fixes them. After that, the final version is launched.

Congratulations, you made it!
