What is Technical Documentation?

By technical documentation, we mean the whole abundance of notes, templates, standards, rules, and guides produced on the way through development. They include any copies that describe the product's functionality or architecture. In other words, technical documentation is a comprehensive how-to guide for developers, administrators, users, and new hires. 

Some tech documentations are openly accessible. For example, here are Uptech’s iOS and Android cookbooks. They are examples of knowledge-base documentation; that describes processes and practices that we use for iOS and Android app development. 

Why Does Software Documentation Matter?

The purposes of software documentation are as follows:   

  • User support. This refers to anything that guides your users throughout the product – user guides, helpdesks, onboarding programs, operating procedures. 
  • Development help. This includes functional and non-functional requirements for product development, software development guides, etc.; 
  • Business info. Data about your company, structure, policies, workflows, employees, and procedures.

The task of writing tech documentation usually falls upon a technical writer. He/she is a person specifically trained to translate product requirements and specifics into the language of technical documents. In other cases, experts like a tech engineer, team lead or a business analyst may be involved in composing the documents.

Waterfall vs Agile Take on Software Documentation

The approach to writing technical documents may vary depending on the framework of team collaboration. Within the Waterfall development scheme, teams usually prepare a significant amount of software documentation before the engineering stage. This approach allows teams to estimate precise budgets and deadlines. Yet, this approach falls flat when it comes to long-term development projects.  

As for Agile development, teams are not overly focused on getting stacks of software documentation from the start. Instead, the technical documents are designed along the way and allows for just-in-time planning. One of the Agile main manifestos proclaims prioritizing “working software over comprehensive documentation -, “ which means producing essential documentation and being focused on the development quality.

Product Documentation Explained

Product technical documentation refers to the product and describes how it should work. It also gives instructions as to what steps should be undertaken to accomplish the requirements. Usually, product documentation consists of technical and non-technical requirements, specifications, business logic, manuals, etc. 

Product documentation also falls into system documentation and user documentation. The first one relates to the system itself and its constituent parts. System documentation comprises requirements documents, design decisions, architecture descriptions, program source code, and FAQs.

User documentation relates to tutorials, which mainly targeted users and system administrators. This includes manuals, user guides, installation instructions, and reference manuals. 

Requirements Documentation

Requirements documents contain information about systems' functionality that explains how the product should work. They are usually written in the form of business rules, user stories, use cases, etc. Such documents' primary purpose is to unveil the product's business purposes, success metrics, functionalities, and maintenance.

For maximum clarity in your requirement documentation, you may use these instruments: 

  • Use links and anchors 
  • Use graphics and diagramming tools
  • User Stories

Technical design documentation

UX design is probably the most creative part of product development. But, that doesn't mean no technical writing is needed. Every stage of UX design building (research, prototyping, usability testing, and the actual designing part) envisages its type of documents and deliverables. Here are some examples of such documents: 

Proto Persona . This is the portrayal of the product's potential user, focusing on behavioral patterns, thoughts, and motivation. This image is composed based on the user interview and surveys conducted during the research stage;

Customer Journey Map. This document reflects the flow that a user persona goes through to accomplish a specific task; 

Scenario maps. Maps are used to combine all user scenarios into a single document.  

User story map. This one is made of the product's backlog and conveys the application's future functions and parts. It may look like a coherent scheme or a table of user stories.   

UI-Kit . This document contains a unified standard for all design patterns of the future product. It covers all possible UI components and types used, explaining how they should interplay.  

 Process Documentation Explained

Process of documentation helps to record essential steps needed to complete some task. Unlike the product documentation, process documents are about how a team should describe the process, instead of dictating what the process is. Process documentation covers all the standards, patterns, and project documentation, like plans, schedules, notes, or even correspondence. Here are some examples of process documentation: 

Plans, estimates, and schedules. These are usually made before the project starts and can be changed throughout the project. 

Reports and metrics. These notes explain how much human resources and time have been spent on the product’s development. 

Working papers. These documents are used to reflect technical ideas and thoughts when the project starts its implementation. 

4 Tips On How to Write Technical Documentation

tips on software documenting

Technical documentation is quite a broad term that encompasses various written documents throughout product development. It could be a challenge to write the documents and keep them systematized. Here are some tips that might help you in handling this process. 

Tip 1: Start With a Software Documentation Plan

Before plunging into the process of writing software documentation, try to make a plan. This will help you figure out which topics you need to cover and which goals your documentation pursues. To this end, your plan should include: 

  • Goals;
  • Existing resources; 
  • Style guides;
  • Outline of topics;
  • Tools and management;
  • Deadline and final deliverables; 

Tip 2: Structure is the Key

Successful technical documentation is inconceivable without a logical structure. Think of the navigational structure of your document, as well as the design. Ensure it is easy for the user, administrator, or team to parse it quickly and find what he/she needs. 

Tip 3: Use a Content Management Tool

Leverage the power of content manager and note-taking apps, like Notion, Atlassian Confluence, or Planio. Few are aware that GitHub provides its wiki system to store and showcase your documents. 

Tip 4: Make Your Software Documents Available

It's agreeable that mobile technology has been dominant for quite a while. Like your website or an app, technical documentation should be accessible on mobile devices so that everyone can check on it at any time and anywhere.
