Learning objectives

In this seminar, participants learn what needs to be considered when dealing with existing code. By differentiating between simple and complex refactorings, the basis is laid for making changes to the code while reducing the risk at the same time. The Mikado method is a method that is suitable for complex refactorings.

Prerequisites

Since refactoring measures are guided by principles, participants must know and master the common principles and practices of software development. Fluency in a programming language (e.g. C#, Java, C++) is required, as exercises will be worked on in the seminar.

Customer testimonials

Here you will find our ProvenExpert profile.

"The clean code training with Stefan gave us a lot of food for thought to rethink our previous approach and to see things from a different perspective, which has made a significant contribution to improving our code quality and our development process. The success factors are certainly the iterative training model built up over a longer period of time, as well as Stefan's competent, entertaining, interesting, goal-oriented and situational training implementation."
Gunter Ziesel, Team Leader eCommerce DevelopmentWürth IT GmbH
"Many thanks for the two refactoring workshop days. The feedback from the team on the events was extremely positive."
Christoph Schmid, Team Leader123erfasst.de GmbH
"Stefan coached our team for over a year in 10 sessions. With Flow Design, he gave us a method to develop cleaner and more maintainable code and to better parallelize the development of a feature in the team. Through a combination of theoretical principles, practical exercises and discussions based on our real projects, he helped us to better understand the requirements for maintainable code and to apply them in practice. This enables us at COMPAREX AG to respond even better to customer requirements and develop high-quality software efficiently."
Tino Schnerwitzki, Team Leader Application DevelopmentCOMPAREX AG
"We used to suffer from legacy code. As a remedy, we found clean code and Stefan, who led us on the path to becoming successful clean coders. Now, developing a modern microservice architecture in a DevOps team is really fun."
Markus Rothhöft, Head of Software DevelopmentM.S.E. Ltd.
"Stefan Lieser's training courses are professionally sound and extremely pleasant on a personal level. He passes on his in-depth experience in a collegial and pointed manner, which makes learning with him both effective and inspiring. For these reasons, more than a dozen of our employees have already been trained by Stefan."
Michael Speer, Management Boardgeneric.de software technologies AG
"The workshops with Stefan have given us a new perspective on our legacy code. Using suitable methods, we were able to optimize the production of new code in the areas of design, programming and automated testing. With legacy code, controlled and measured refactoring and putting the code under test leads to better software quality as well as faster and therefore more cost-effective expansion options."
Alexander Schmidt, Head of Software DevelopmentCompra GmbH
"The iterative implementation of the workshop with Stefan has enabled us to make great progress in improving code quality within six months. The key factors for us were the iterative approach, the practical exercises and the joint analyses of the individual solutions, as well as the small working groups."
Rainer Trunk, Process ManagerODS Marketing GmbH
"In the CCD workshops, Stefan challenges us to question the familiar and break new ground. In the workshops, Stefan doesn't mince his words and always gets us out of our comfort zone. The regular practice that Stefan has encouraged us to do has become an important part of our work."
Klaus Stein, Manager responsible for training and developmentMitutoyo CTL Germany GmbH
