2 Committment to New Approaches Commitment Contact Contact Names Names Awareness Awareness Buzzwords Buzzwords Understanding Understanding Concepts Concepts Trial Trial Opportunities Opportunities Time Adoption Adoption Performance Performance Routine Routine Tuning Tuning Technology Transition & Assimilation Pilot Testing Slide 2

3 Stages in the Change Process Level1: Identity Level 2: Beliefs Level 3: Capabilities Vision of the Company Traditions Mission The way to see yourself, others, your company, the competitors, the world Core Competences Capability to learn Capability to anticipate Level 4: Culture How to solve conflicts How to manage change How to delegate Level 5: Environment Image Customers Competitive Position Slide 3

4 Managing Resistance Address problems explicitly Predict and verify sources of resistance Involve the people that will be affected Develop mitigation strategies Create an environment in which it is safe to express objections Remember that people may resist for good reasons Slide 4

11 Scores per Process Area The relative scores gives you an indication of the strengths and weaknesses of each of the process areas. n = 48 The Total Score provides a baseline for determining whether specific improvement actions did work. This chart provides an overview of the overal score as well as the score per process area. Slide 11

12 Scores per Process Attribute The relative scores give you an indication of the strengths and weaknesses of each of the process attributes. n = 48 This gives you an impression whether attention is is given to all relevant aspects of the software processes that are identified. This chart provides an overview of the overal score as well as the score per process attribute. Slide 12

13 Overview of Assessment Results The relative scores give you an indication of the particular strengths and weaknesses for each process area and each attribute. This chart provides an overview of all scores. Extremely strong and weak points are easily spotted using this chart. Slide 13

14 Process Existence per Attribute The relative scores gives you an indication of the existence of the processes associated with each process area. Scores below 75% indicate the absence of software processes that are in most cases essential. n = 48 Processes that are supposed to be irrelevant in your case can be set to Not Applicable. This chart provides an overview of the overal existence as well as existence per Process Area. Slide 14
