Water Scrum Fall | Glossary

 

Definition

Water-Scrum-fall is an hybrid approach that combines Waterfall and Scrum development methodologies in its approach to Application Life cycle Management. It is used for the development process for a software product as one large project. At the end of which, the team releases the working software to an operations team for install and maintenance. Only the business owner, or Product Owner sees the finished product. This is in contrast to an approach that only uses Scrum, or Agile, where work is done in sprints.

Variability | Glossary

 

Definition

Variability is as aspect that is often bound towards reduction by System Developers. The focus is put on eliminating Variability at the ideal moment so that it doesn’t perpetuate a risk-avoidance culture beforehand. The goal is to satisfy their current customer base, without worrying about what the best practices are to handle said variations of requirements in the particular system. Scaling an Agile method up to adopting the practices of Variability Management is a challenging process.
