Competency Levels in TTCN3 A CMM Like Approach

Competency Levels in TTCN-3 A CMM Like Approach

Agenda • • • Challenges Proposed Model TTCN-3 User Levels TTCN-3 Organizational Level Benefits

Challenges • Lack of expertise • General inertia to change • Unable to judge the applicability and impact • Syntax and semantics • Test designs • Data management Lack of understanding Language level issues Architecture Tools • Automation and Optimizations • Issues pertaining to Optimized frameworks and automation tools & Management • TTCN-3 architecture for domains • Estimations • Fault model related issues

Proposed Model • Competency Level for Engineers • Competency Level for Organizations

Benefits - Competency Level for Engineers – Easy to find a role – Easy to plan for a project – Easy to define career path in an organization

Benefits - Competency Level for Organizations – Helps to win new business based on the company’s TTCN-3 competency level and domain expertise – Easy for the management to handle the TTCN-3 engineers
