If you are a software developer, you probably dislike the process of documenting design requirements. You would much rather dive straight into the code and get the job done. However, approaching software development this way often leads to disastrous results. 

It is important that the entire team is on board with what needs to be built and how. Being in congruence with design requirements is also crucial while working with a client. It ensures that both parties agree on the deliverables so that there’s no confusion at the time of the handover.

Therefore, even though it can feel like a chore sometimes, documenting design requirements and creating software design documents is a must for every software developer.

Before we introduce you to our awesome software design documentation template, let’s take a quick look at what exactly is a software design document and what are the things one needs to include in these documents.

 

What is a Software Design Document?

A software design document (also known as a software design specification or technical specification documents) is a written report of a software product describing its overall architecture.

Such documents are usually written by software designers or project managers and are given to the software development team to give them an overview of what needs to be built and how.

A Software design document helps to ensure the design specs of the software are understood and it’s clear to all. It specifies what is possible with the product and how it can be accomplished.

Why are Software Design Documents Important?

Software design documents are an important way of looping everyone into the process who is involved in the product. It is for everyone to understand what is possible, what is not possible and the system that will be designed.

Design documents are created to coordinate efforts of a large team, give them a stable reference point, and describe all parts of the software and how they will operate.

Engineers working on different softwareIt assures that the product is built meeting the needs and is on par with what was agreed upon prior to the inception of the product/software.

Software design documents not only help others understand your system and provides documentation for future projects, but it also forces you to think through the entire system architecture.

This ensures you go through every possible roadblock or challenge you might face, thereby exposing all gaps in your thinking.

Now that you know the importance of creating a software design document, let’s us explore what one needs to include in a software design document in order to make it competent.

 

What You Should Include in Your Software Design Document?

A typical software requirements document should involve the following details:

Title: Add the title of the Software Design Document

Introduction: Provide an overview of the entire document

System Overview: Provide a general description and functionality of the software system.

Design Considerations: Describe the issues that need to be addressed before creating a design solution

  • Assumptions and Dependencies: Describe any assumptions that may be wrong or any dependencies on other things.
  • General Constraints: Describe any constraints that could have an impact on the design of the software.
  • Goals and Guidelines: Describe any goals and guidelines for the design of the software.
  • Development Methods: Describe the software design method that will be used.

A software design document Architectural Strategies: Describe the strategies that will be used that will affect the system.

System Architecture: This section should provide a high-level overview of how the functionality and responsibilities of the system were partitioned and then assigned to subsystems or components.

Policies and Tactics: Describe any design policies and/or tactics that do not have sweeping architectural implications (meaning they would not significantly affect the overall organization of the system and its high-level structures).

Detailed System Design: Most components described in the System Architecture section will require a more detailed discussion. Other lower-level components and subcomponents may need to be described as well.

Glossary: An ordered list of defined terms and concepts used throughout the document.

Now that you know the importance and elements of a software design document, it’s time to put that information to test by using a documentation tool like Bit.

Bit.ai is a new-age software documentation and knowledge management tool that helps teams to collaborate, share, track, and manage all company knowledge in one place. Bit documents, unlike your standard Word Docs, are interactive. This means developers can easily add code blocks to a document with a single click!

Bit.ai: Document creation tool

Whether your team is creating software design documentation, technical specs sheet, training manuals, best practices, client support material, etc, they can easily add code blocks and embed snippets of GitHub Gists and Pastebin code directly into a Bit document. It’s a smart way to add context to the code snippets you are sharing.

Collaborate with other developers and clients

Multiple people can simultaneously collaborate on a Bit smart document in real-time. It’s a great way for software developers to handle different aspects of the software together under a single roof.

Bit’s sleek, minimal and distraction-free editor makes a great tool for documentation. You can bring all the important stakeholders on a common document and make sure everyone knows what is agreed upon.

Distraction-free and quick documentation

The best part is Bit’s support for Markdown which allows developers to quickly create and format text without any distractions.

Once you are done creating your documents, you can easily export them as PDFs, Word files, Markdown and much more. Markdown is supported by GitHub and other software development tools, making it easy to share the work you do inside of Bit with other platforms.

Keep software documents safe and secure

Bit allows users to manage permissions and information access that suits your organizational needs. It supports features like document tracking, password protection, file access restrictions, etc. that help keep your important company information safe.

This means that all your software documents are safe and secure and are only accessible to those who have been given access to it.

Work with your favorite apps!

We recommend that developers use video recording tools like CloudApp and Loom to bring their video screen sharing tutorials directly into their software design documents.

Add rich media integrations to your software design document

It’s a smart way to share screens and provide direction to your team, future employees and clients you’re working with. Bit works with these two applications along with 100+ other integrations to make sure your technical documentation brings in various types of digital content.

Recommended power links and files you can add to your software design documents are:

  • Any weblink
  • GitHub
  • PDFs, PowerPoint in Google Drive/OneDrive
  • Google Sheets, OneDrive Excel, Airtable
  • YouTube, Vimeo
  • Social Media posts
  • Draw.io & Lucidcharts
  • InVision, Framer, Figma

Bit provides a common workplace for software developers to collaborate, document, share their knowledge, brainstorm ideas, store digital assets, and innovate together. The best part is that this knowledge is safely secured in your workspaces and can be shared (or kept private) with anyone in your organization or the public!

Here are some of the main benefits of using Bit:

  1. Collaborate in real-time
  2. Interlink your software design document and other documents.
  3. Create fully responsive documents.
  4. Create software design documents that are only visible to yourself or your colleagues.
