Working with a software house requires that you define your project clearly, well in advance, so that they can execute it properly. The software house needs to have a clear idea of you what you need to get done, so having this information in a single document can be quite helpful. This is where a software requirement specification (SRS) matters.
So, what’s the best way to create an SRS that is clear and understandable? Why is an SRS so important during web development? What do you absolutely have to include in an SRS? Here's all you need to know about an SRS.
An SRS is a technical document that has all the requirements and technicalities pertaining to your product. This document gives the development team a clear picture of the tasks. It needs to be as detailed as possible. An SRS includes the expectations and deliverables of the project - such as the functionalities, technologies, etc. The requirements can be both technical and non-technical.
A well-written SRS benefits both parties. While you might use it to define your expectations, a software house uses it to assess the amount of work and resources required based on which then can send you a cost estimate.
Now that you know why it’s important to write an SRS, how do you actually write it? Here are some guidelines to follow:
Begin with an introduction to the project. What the product is built for, the key business goals, the end users/target audience, etc. are good details to start with.
What are the main functionalities of this product? You can create user personas to define the various functionalities more thoughtfully. Describe the functionalities clearly, with step-by-step execution if possible. Include the various roles involved as well as the permissions associated with each role.
Describe the functionalities accurately such that there is no confusion ahead. You can include flowcharts and graphs to create a pictorial representation of the user flow.
In the case of larger projects, don’t forget to prioritize the functionalities. This makes planning the work much easier and can come in handy in a time crunch.
Do you have a design ready? Or have seen a design that you like and want to replicate? Any such information should also be shared as it makes the UI development a whole lot easier. Even some screenshots for inspiration can let the software house know of the type of UI you’re looking for.
For more clarity about the project, an SRS must also have non-technical requirements. This includes the quality expectations of the product, the expected traffic, speed/performance expectations, deadlines, any limits, security requirements, data backups, etc.
You can also include more information about the target audience here, like the general usage behaviour and frequency of use. If there are any specific technological requirements like the use of specific frameworks or programming languages or the integration of the product with other products, this needs to be mentioned as well.
An SRS has a major impact on the implementation of a project. A well-defined SRS is accurate, on-the-point, detailed, and contains all the necessary information. Based on the SRS, software houses can make a fair estimate for the project and plan your project accordingly.
