Description:

The main objectives of this project were focused on two areas:

1. Upgrade of the AAA system to enhance capacity as well as to improve redundancy by changing the failover mechanism to a second, geographically separate site
2. Implement a new PCF (Policy Control Function) in order to provide the product management teams with required functionality to limit throughput rates for various tariffs dynamically

Responsibilities:

• Coached current project managers in order to improve their skillsets in a number of areas (e.g. risk, dependency and vendor management, communication across multiple project teams, testing and quality management approaches) 
• Drove the approach to split the project in two pieces (AAA Upgrade and PCRF Implementation) in order to decrease complexity and reduce risk as well as to release pressure on the day-to-day operation
• Updated plans and re-negotiate delivery schedules with the major stakeholders
• Implemented contingency measures to ensure project progress 
• Negotiated milestone dates and scope with dependent system delivery and product/service projects

Duration:

• 10 months
