10 Reasons Why You Should Write Technical Specification

Wonder why you’d need a specification and what the benefits would be? For a start let’s figure out the definition itself.

Technical specification or documentation is a document that every project or product manager must write before starting the actual software development. It has a set of requirements for the product in order for it to work as it was meant to be. This list of requirements has to be met before the development is complete.


Making your requirements clear, there’s no room for confusion or doubt.

We’ve got 10 key reasons as to why you shouldn’t skimp when it comes to specifications:

  • It allows seeing your goal as a client more clearly.
  • The whole team which works on a particular project can use the documentation as a reference to understand how features should work.
  • Project Manager will be able to plan the work easily, create features that can be implemented right out of the documentation.
  • Quality Assurance engineer can test an application following the documentation.
  • Features are specified in the document and can’t be lost or forgotten.

A technical requirement document empowers the team to come to a mutual understanding.
  • The features are described in one place and can be easily found.
  • If a project is really big it gets developed over a few years. Therefore you may need to know how a particular feature implemented a few years ago works.
  • It helps to see the whole picture of how the project should work, thus helping Quality Assurance engineer to ensure that features work as expected.
  • It helps both sides to find needed information such as shortcuts or a particular screen/functionality etc.
  • It saves money as it reduces the amount of time discussing the details of the project and the vision of a customer.

That’s why by making your requirements clear there’s no room for confusion or doubt which can only make for a more efficient and effective process.

In case, you don’t create a technical requirement document, real problems can develop.

Here is a list for you what happens in case of a lack of documentation:

  • Product Owner/Project Manager spends a lot more time discussing features with a customer.
  • Quality Assurance engineer can’t assure the reliability of the features as they are not described and the information about the whole project is scattered on a board or a cloud.
  • Development team will always distract the Product Owner/Project Manager to consult how features or any other details should work.
  • The development team can misunderstand how features must function and implement it by their judgment. That can lead to spending more money rather than if they had documentation providing the information.
  • It’s harder to prove that a feature is discussed to work in a particular way unless both sides the client and the development team have proves of it. But anyway it will result in conflicts which are not an ally of any business.
  • A lot more bugs emerge due to misunderstandings of how features should run.

Conclusion

Creating documentation may not be easy for a customer, but it has explicit advantages for both the business and for the development company.

From our personal experience, a technical requirement document empowers the team to come to a mutual understanding of what is required, technically, to make your project or product a success.
