Scrum+:: Is it “ScrumBut” or “ScrumAnd”

In this paper we analyze the challenges we may encounter by tweaking core practices of Scrum framework (ScrumBut) or benefits we may get by blending some non-Scrum practices with Scrum framework (ScrumAnd). Detailed analysis is carried out on ScrumBut and ScrumAnd and their impact on project success or failure is studied. As it is not always easy to conclude if any Agile project is following ScrumBut or ScromAnd, we discuss two principles, derived from OOD, to distinguish between the two. Use of these principles is illustrated by application on real life scenarios. By application of these principles, a Scrum Practitioner can easily find out the methodology used in a particular project implementation.
