Agile Software Development Methods and Hybridization Possibilities Beyond Scrumban

Traditional software development methods could no longer cope with the fast-growing software development market, as well as the increasing complexity of the software being developed. Using outdated practices was no longer viable as it could lead to reduced competitiveness and losing possible revenue. Therefore, many companies have turned to implementing agile software development methods to keep up with the fast-paced market. Agile allows them to develop quickly, consistently, and in a flexible manner. However, different approaches are better suited for different projects, and, sometimes, an approach combining appropriate aspects of several other approaches is the best option. This paper describes five popular agile software development approaches of which four can be considered "pure", namely Scrum, Lean, Kanban, and Kaizen, and a hybrid approach called Scrumban. The paper then aims to assess other possible combinations of the approaches, both found in the literature and those not yet considered.
