Before writing a single scrap of code, a wise software engineer will always write a technical specification, also known as a tech spec. This document prevents the development team from wasting time and effort on unnecessary steps or misunderstandings internally and among stakeholders.

This article takes a look at the value of a technical specification and the importance of using a professional template. monday.com has worked closely with engineers to craft a technical specification template that saves time and ensures that all bases are covered.

What is a technical specification?

A technical specification is a detailed and comprehensive document that describes all technical procedures related to product development. It covers all the vital, nitty-gritty information about the process of product development.

The development team lead usually writes a technical specification. After reading a technical specification, the development team and stakeholders should know:

  • How the proposed product is going to behave
  • What it can and can’t do
  • How it’s going to be developed
  • All systems that are going to be used/changed/created to assist development, security measures for data privacy
  • The plan for rollout and rollback if necessary
  • Business-related metrics
  • Support and maintenance plans
  • The project timeline

Technical specification vs. functional specification

A technical specification is sometimes confused with a functional specification. While both documents lay the groundwork for a successful project, there are key differences.

A functional specification is based on business requirements. It focuses on user experience by looking at product functionality. In contrast, a technical specification focuses on internal programming. It includes plans for implementation, testing, and the benefits of specific features.

Why use a technical specification?

A technical specification, especially written using a good template, is like your product development bible. Here’s why a well-written technical specification is so important.

Keeps everyone on the same page

It’s easier than you might think for a development team to agree on specific requirements and goals but end up building different things or failing to deliver on promises made to stakeholders. A well-written technical specification keeps your engineers on task and your stakeholders well-informed by making sure that everyone sees it from the same point of view.

Lead engineers should ensure that technical specifications communicate everything known about the product requirements. It should also communicate its goals, features, limitations, and the timeline necessary to build it.

Provides clarity

Because of the precise nature of software engineering, even the smallest misunderstanding can cause catastrophic setbacks. It’s also vital for stakeholders and investors to understand exactly what is possible. People with less expertise tend to underestimate the technical requirements of ambitious projects, and any unrealistic expectations should be nipped in the bud. Using a technical specification template lets you rest assured that what you are planning to build is possible and that all your bases are covered, down to the last detail.

Prompts important questions

A technical specification also gives the author a good idea of open questions that still need answering. Some elements of the project may only become clear after trial and error. The estimates of time and resources needed may shift and change during the project. If there are any uncertainties on your roadmap, a technical specification helps identify them and their potential impact.

A technical specification also acts as a rationale for your approach to a project. There should always be justification for the methods you choose to use in your project. When writing your specifications documents, you may find that there is a better solution. A technical specification helps clarify things for the development team and stakeholders.

What are the steps to complete a technical specification?

Let’s look at a practical example of a technical specification at work. In this example, you are designing a new food delivery app. A comprehensive technical specification template will help clarify your goals and nail down the details.

Preliminary questions

First, you’d need to establish the way your app behaves. You want to answer questions like:

  • What do you want your app to do?
  • What problem does it solve for the user?
  • How will your product improve on existing food delivery apps out there?

Here’s your chance to be specific about what your system can and cannot handle. This is the section that paints a detailed picture of what you want to build.

Set limitations

Now you need to establish what is not possible for the development of your app. This is called the “out of scope” section of the technical specification. Any grand, unrealistic ideas from stakeholders need to be confronted with experience-based evidence from the project manager. For example, the app cannot accept payments in cryptocurrency.

Determine your approach

In this section of your technical specification, you can outline how you plan to tackle each element of your project. You should also include your reasoning. For example, if you want to use biometric security for user login, here is where you explain why it is the best approach and how you plan to execute it.

Another important functional specification is security and privacy. Your document should outline how you plan to protect user privacy and prevent breaches.

Testing and support

Finally, you outline your testing, deployment, and support strategies. For example, if you have arranged for a 100-person alpha test, detail that here. You can specify what platforms you’ll release on, how you’ll monitor feedback, and how you’ll offer support.

Because of the nature of technical specifications, these documents can get pretty detailed. The set of requirements you include will depend on the product you are building. Case in point is this technical specification by NetBit for a 650 Watt DC-DC Power Module.
