Worry not. This blog will guide you on how to write a technical specification document. That’s not all. We will also share a technical specification document template to use for creating these documents. 


What is a Technical Specification Document?

A company defines the technical requirements first whenever it works on a project, product, or system. 

By technical requirements, I mean: 

  • Technical specifications and design
  • Development process 
  • Business requirements 
  • Internal standards 
  • Best practices 
  • Work involved 
  • Impact 
  • Timeline of features, projects, or services 

The documents in which all this information gets laid out are called technical specification documents. It also has other names like: 

  • Technical design document 
  • Software design documentation
  • Engineering documentation 

Who writes these documents? Most of the time, it’s engineers who are either building a solution or will implement it. But, for larger projects, technical leads, project leads, or senior engineers also get involved in creating these documents.

So, how to write this documentation? Find that out in the next section.

How to Write Technical Specification Documents?

  1. Header

    The header is the first thing you will include in the documentation. It will consist of the project name, the date, the author of the document, and contributing team members in the project.  

  2. Overview

    Here add a summary of the project and share links to external documents. Share your project specifications, marketing, and engineering documents, which will provide a context to the documentation. 

    What kind of general approach will you take in this project? Give a summary of that in this section. 

    Also, share a rough estimate of the overall project completion time and its size. 

  3. Goals and Product Requirements

    Defining your project goals and technical requirements is essential. Having clear goals is crucial to make the project successful. Hence, have a clear idea of what problems you are trying to solve through this new product.  

    Are all the project stakeholders on the same page? Many times, teams don’t create any consensus among each other when deciding a goal. It causes team members to go in a different direction as there was no clear plan on who is supposed to do what.  

    Ensure this doesn’t happen to the projects that you are working on in the company. 

  4. Assumptions

    This section covers what you will build and how much the system can handle? It’s about sharing the technical behaviors of the new product and its limitations. 

    Be specific and detail oriented. Define SLAs (service level agreement), capacity, and failure tolerance of your product.  

  5. Out of Scope

    Here, you will cover everything that’s off the table. Share all the features that aren’t going to get included in the final product and the internal process which you won’t be part of in the project. 

    This section is essential as it will prevent unwanted work and misunderstandings between team members and other stakeholders. You can also name this section as non-goals.  

  6. Open Questions

    List all the unresolved issues and TBD (to be determined) questions in this section whenever you write for technical specs. 

  7. Approach

    Explain the solutions to your target audience in this section. The level of detail is up to you to decide. 

    Every sub-system, new technology choice, and standard should have its sub-section. Also, share whatever other options you are considering. You can even create a new section for it under the name “Other options considered.” 

  8. Components

    Give a recap of your proposed approach in this section. Provide an easy to read bullet points of all the systems that will get created or changed throughout the project cycle.

  9. Schema Changes

    Whenever there is a change in data storage, list them here, even if it is a minor change. You can also add UML diagrams or provide complete schemas in this section. 

    Create a consensus within the team regarding what kind of data you will store in this section, how much, and how relational it should be. Work out on details later.   

  10. Security and Privacy

    When working on a new product, it’s essential to think about customer data protection, personal information, encryption, and attack vectors. Share your thoughts on this matter in this section. 

  11. Test Plan

    Describe your testing strategy in this section. It should cover unit and integration tests, manual test plans, and automated test suites. 

  12. Deployment and Rollout

    What kind of logistics and order of preparation required for the following release of the new product. All of this will get covered in this section. Also, include configuration management, secrets management, database changes, migrations, and sign-off process.  

  13. Rollback Plan

    What if a customer hates a feature? Or there is a failed integration. Maybe something went wrong with the deployment of the system. 

    Is it possible to roll back to the previous system? What metrics and alerts should we observe? 

    Explain all of these in this section.    

  14. Monitoring and Logging

    Explain how you will detect problems in the system, track SLAs, and determine if the system is healthy. Also, include how you will search through logs to track down customer issues or bugs. 

  15. Metrics

    Explain how you will answer business-level questions regarding the impact and benefit of different features of the final product.   

  16. Long Term Support

    Include answers for the questions like: 

    • Who will maintain this software in the future? 
    • What will be the long-term costs for supporting the product? 
    • What happens if essential people leave the company, are there any plans to transfer their knowledge?  
  17. Timeline and Components

    Give a rough estimation of task completion, by the product team, in day-sized estimates. Here is an example, the product team implements all the X features: ~4 person-days. 

    Be realistic in your goals. Adopt actual person-calendar-days and don’t be theoretical like, “if we are completely focused..” estimates. Add padding for risks, integrations, and meetings. Cover the tasks required for all teams, not just your own.

FAQs

A functional specification is a document used for describing a product’s intended capabilities, appearance, and interactions with users in detail. It may also contain a description of user tasks, dependencies on other products, and usability criteria.

When additional functionality, features, requirements, or work are added in product specs without any authorization, that’s what we call scope creep.

Here are some key items that are often included in this documentation:

  • Revision log
  • Executive summary
  • Assumptions, risks, and dependencies
  • Requirements
  • References
  • Glossary

Here are the steps that you can follow to write excellent documentation:

  • Create an outline for your software requirements specification. You can even use the SRS template
  • Start with a purpose
  • Give an overview of what you will build
  • Detail your specific requirements
  • Get approval for the SRS

Here are the steps that you can follow to write an exceptional product specifications sheet:

  • Define the problem
  • Understand customer input
  • Include your entire business in the discussion. Stakeholders should have to say and will be beneficial in the development process
  • Choose which product specifications to include
  • Conduct a user testing
