Why documentation is important

Dmitrii Korolkov

Being a developer is definitely exciting, but how about being good proficient and exited in the same time? One of the good ways to keep the job in a perfect development and business shape is to maintain and have good documentation. The most important reasons why we need that are: knowledge transfer, application tracking ( while working on multiple projects ), software maintenance. Let’s talk about important points:

The environment of the server:

Imagine maintaining and developing the application without understanding how the environment was set up. It will take bunch of time just to figure out the things, whereas with the documentation we can have easy start with understanding of:

  • application details, the current version
  • server parameters
  • directory path for the code
  • application acccess
  • current OS
  • POC in case of questions

Business understanding – what am I doing here?

The worst thing that could happen is if the manager or hired personal doesn’t know what are they doing, why they are doing this or not something else. When people are on the same page and understand the purposes, functionality and goals – it’s much easier to cooperate and work as a team. Also, from the side of a manager it will be more comfortable to analyze the possible problems, for developers catch the job easier and cut “on boarding” process, saving thousands of company’s $$ and gaining productivity. 


We can handle most of the issues from the code side, but how about the data errors? Without good documentation it will be very hard to for a new developer to understand how specific data-related problem was resolved before. 

Environment set-up:

Installing, setting up configuration and launching applications from scratch might be tricky and unclear, every step of the process is very important. The good documentation will provide steps, list of libraries, server versions and parameters – everything that will ensure that environment is ready to be used for the project and works as intended. 

Software and deployment

It’s always good to have deployment processes to be documented when we release new updates. The information about releases, where they are located and could be found is
