In addition to trainings, I want to share my experience and knowledge also as books. In this section you will find books that have been already written, are in the process of being written, or have just been considered to be written in the future.
With all the books, my plan is to, first, write them in Estonian (1. draft), add feedback from test readers (2. draft), publish as e-book, print them, and also translate to English and publish them as both e-book and printed book.
Optimal documentation
useful, up to date and convenient

Optimal documentation doesn’t mean you have to do more – it means to work smarter.
The goal of this book is to help achieve a balance in documentation: creating useful and up-to-date documentation that is neither overly burdensome nor excessively time-consuming.
The book is meant for IT Analysts, Product Managers and Project Managers who want to create clear, practical and useful documentation.
