Requirement specifications are the main project document, describing all its technical and non-technical issues. Any of your ideas are just ideas until specifications developed. In this article, we will explain why this document is so important when it’s correct to begin development and what exactly it should contain.


If you don’t describe the expected result, don’t formulate a clear task and project requirements, you will: 

And in order to prevent this, it is important to write requirement specifications. In order for the team to understand specific tasks and be able to implement them so that the expectation and the final product result coincide.


  1. Formation of business requirements

This is the foundation for project implementation. At this stage goals and budgets are set. Here the SOW development process begins because it determines the future product success. All further work on specifications should be based on business requirements.

  1. MVP development

It’s almost impossible to build the perfect product on the first try. In any case, it will change based on the feedback of the market and users. Therefore, it is logical to start with MVP – the minimum viable product. For the development of MVP, the SOW is as important as for the development of the main product. At this stage, the specifications task defines:

So, specifications at the MVP development stage describe which functions are needed and how it is necessary (minimal and sufficient) to implement in order to test the hypothesis.

  1. Main product development

After the successful launch of MVP, requirements for the main product are finalized based on the results: a positive market reaction, as confirmation that the business model is working. That is necessary to take into account and describe in the SOW, we have written in detail in the 3rd section of this document. At this stage, requirements play a crucial role:

At this stage, specifications are a complete guide to action, completely describing all important points, starting from a business analysis of the market and target audience, ending with colors, fonts, and other details.

  1. Marketing promotion

In the good SOW, there is a place for market research, competitors, communication channels with potential users, and resources for promotion. Marketing promotion is the logical and necessary project support at the start and after it. If you don’t initially plan marketing activity, you probably won’t take into account the resources (in particular, the money) needed for a confident release. You run the risk of being left completely without promotion since the main resources will go to development. So, without the described marketing, you can confront a lot of problems:

At this stage, specifications are the answer to the question “what to do after the release?”

  1. Describe a problem
  1. Determine personal goals
  1. Describe a business model
  1. Form a financial model
  1. Describe use cases
  1. Describe Functional / Technical requirements
  1. Describe Non-Functional requirements

Project wireframes and flow

The ideal picture is described above, which is not always needed and feasible. Depending on your goals, project size, and product complexity, some points may be skipped. The main thing is to answer all the questions that are important for the project and document it at the SOW. Then, you will be sure that you are moving in the right direction at all stages of development.
