What problems await us in a collaboration between Scrum and waterfall teams? What are the antidotes?

Submitted by Andreas Schliep on 08/20/2013

"I work in a relatively conservative company, and often come to the point that in large projects Scrum teams and waterfall teams need to work together. This gives us many problems with coordination, the "change processes" and the cultures. I need some material so that I can work in the direction that we use only one PM framework in the same project. What other problems can we expect if we use different frameworks and what are the antidotes to them? I would be very happy if you give me some literature hints which could illuminate the problem "Scrum Waterfall Hybrid."

There are a lot of hurdles. The biggest challenge is the understanding of the common approach. The core of many project management processes is the assumption that the development takes place in the IT - and thus the exchange of a development process has no effect on anything around. Once this is understood by Business respectively Product Management and IT divisions, the next steps often result already from the premise of cooperation. Of course there are preliminary considerations of professional and technical nature. Of course one must first collect the gross requirements - for example create a vision, design a rough roadmap. But by that time at the latest the development belongs to the team. And from that point, the product management is not "left out". This is precisely the fundamental difference. So you can also revitalize the existent quality gates by thinking together about what you want to say at what time. Here there are three premises for you:

  • An estimate over a certain delivery date always requires at least three sprints
  • The requirements are never "finished", each Product Backlog Item is like a Change Request
  • We want to minimize work that lies between development completion and putting into operation.

My colleagues have to deal with this problem for some time already. First of all I would name "New New Product Development Game" and the waterfall process itself. In the latter Winston Royce criticized the model itself - which seems to have been overlooked by many readers. Additionally I’ll give you some more articles which may help.

Last but not least, pitfalls during the introduction of Scrum:

My conclusion?

The antidote to the problems that arise during the transition of the PM framework is called "collaboration". Make everyone smarter, evaluate, discuss, find a way which appears fairly reasonable - and improve yourselves together!
