DMADV is an acronym for Define, Measure, Analyze, Design and Verify. The last 2 stages of the DMAIC process are replaced with Design and Verify to indicate that you design the best process and verify that it is the best process. A lot of companies will not use this acronym and prefer to keep DMAIC clearly stated.
There are two basic types of roles and responsibilities that employees should be expected to assume and to be evaluated on. The first role is that of technical expert. The employee must be able to do the work well. The second type is the social role that involves the management of the processes of the team. Both roles are important to the team's success and performance improvement. In his book, Building Productive Teams, Glenn H. Varney explains the importance of clarifying the roles of team members.
One person can be member of multiple business roles (e.g. Sales manager and Employee), and multiple persons can be member of the same business role. The business role is the one that launches a process, makes decisions on which of the available paths in the process to take and in the end finishes the process. In an SAP context a (technical) role is also defined. Roles are collections of activities which allow a user to use one or more business scenarios of an organization. The transactions, reports and web-based applications in the roles are accessed via user menus.
