Creating a project specification and defining the scope of an IT project can be challenging for someone who is not professionally involved in the industry. However, it is worth taking the time to do it thoroughly and accurately.

For the developer, the specification serves as a primary source of information, outlining what needs to be done and how. But for the client, it is equally important, as it can help resolve disputes and provide clarity throughout the project’s development.

When ordering the development of a software application or a website, the first thing you’ll be asked for is a functional specification, a requirement specification, or simply a project specification. Either you’ll need to provide it, or the first phase of work will involve creating this document.

A specification is crucial because nothing facilitates planning and execution more effectively than well-written documentation. However, it also serves another important purpose.

A project specification protects both sides

The contractor must clearly understand what they are committing to, what they are being paid for, and what the client expects from the final product. On the other hand, the investor needs to know exactly what they are paying for and what they have the right to demand.

Imagine hiring a construction team to build a house. You define all the details, the team gets to work, and after completion, you realize that some partition walls inside the house haven’t been built, even though you wanted them.

In such a case, the builder would first check the construction plan to see whether those elements were included in the order. If everything was agreed upon verbally, without any documentation, you would have no way to make claims.

On the other hand, if a specific wall was marked in the plan and the contractor forgot about it, you have the right to request corrections at no additional cost.

This is, of course, a simplified example, but similar situations often arise in IT projects as well.

A project specification serves as a reference point for both the developer and the client, helping verify the quality and completeness of the delivered work.

A specification helps with preparation

A well-prepared project documentation also serves as an excellent source of knowledge about the project before its implementation.

A properly written project specification should include a list of all materials that the client must provide to the developer so that the project can be carried out smoothly.

A developer doesn’t necessarily need the company logo, all written content, or graphic materials at the start. However, experience shows that if all essential materials are not gathered in the early stages, it becomes much harder to coordinate them later. Not to mention, the people responsible for the project – on both sides – might change over time.

A detailed list of necessary materials, recorded in the project documentation, helps avoid such challenges.

What’s the most important?

Every IT project should be divided into modules and smaller, independent components, which are developed separately before being assembled into one complete system. This approach allows for distributing tasks among an entire team or multiple development teams, enabling them to work in parallel.

The challenge is that, amid hundreds of tasks, it’s easy to lose track of the overall project – focusing too much on details and forgetting about its core functionalities. That’s why, when breaking down the project into smaller modules during specification creation, it’s crucial to prioritize each element.

A clearly defined project goal and an understanding of the importance of each function ensure that the most critical aspects are addressed first.

When working on your project, remember – a precisely written project specification isn’t some pointless requirement from overly meticulous developers; it’s a vital document that ensures your project is successfully completed.
