The paper introduce to challenges in automation of continuous processes in companies with many active software development projects. Usually companies have automation solutions for particular projects. When new software development projects are coming, companies would like to save up resources and efforts needed for automation solutions in these projects. In case when automation solutions, implemented in existing projects, are reusable, they could be used in new project without additional efforts for refactoring, development automation solution from scratch etc. Current paper provides an approach for development of library of reusable functions. This library allows reusing implemented automation functions in the different projects and in the different workflows. Finally, a prototype is developed for practical experiments. Based on its results, benefits, disadvantages and improvement directions of provided approach are detected.
