APAC is responsible for the EAD System Implementation Project's PROGRAMME MANAGEMENT on behalf of Frequentis, which has led the Consortium since 01 July 2000. The major challenge in this project is its complex and distributed environment. Due to the wide scope of the project and the fact that the know-how is distributed over several subsystem experts who belong to different companies, a Design Authority Team was established, which is responsible for the technical decisions. Eurocontrol representatives attend all Design Authority Meetings as observers and advisors. An incremental development approach was chosen in order to provide early results for validation by the clients and to minimise the design risk.

The top-level organisational chart shows the complexity of the EAD organisation:

APAC implemented a very lean project management team that strongly relies on the results of both quality and configuration management. The implemented state-of-the-art management procedures, including Earned Value progress tracing, facilitate the early identification of potential delays and other problems.

APAC's QUALITY MANAGEMENT AND CONFIGURATION MANAGEMENT
is the basis for efficient and effective Project Management. To date, about 15,000 items (documents and correspondence) have been handled by the Configuration Management based on a Lotus Notes database. Quality Management supports Programme Management in action tracing, audits, progress evaluations, risk tracing, reviews, quality checks and much more.

VERIFICATION AND VALIDATION MANAGEMENT
is performed by APAC. State-of-the-art V&V is defined and implemented for the EAD SW and HW. Well-defined and formalised processes on three levels verify that the EAD system is built as specified. All V&V processes are performed for each increment - EAD is developed by an incremental development approach. TeamEAD Test Management database contact (TestDB): Susanne Lanzerstorfer, laz@apac.at.

Subsystem V&V
The subsystems are obliged to follow a defined and formalised V&V process from module testing to the subsystem FAT. The subsystem will only be accepted by the TeamEAD V&V manager for system integration if it has successfully passed the subsystem FAT.

System V&V
After successful integration of the subsystem, the TeamEAD V&V team performs the system tests, which consist of a subset of subsystem tests extended by system tests.

System Acceptance V&V
Eurocontrol and the Pilot Clients perform the system acceptance tests based on system test procedures, which are extended by additional workflow and free tests.
