The CoRe project was the HSP-006 (Core Requirements for ATM Working Positions) project of the EATM Human Resources Management programme. The purpose of the CoRe project was to consolidate and disseminate good practice on the requirements capture, design, and evaluation of ATM working positions for European ATM.
The project was completed in December 2002, on time and within budget.

The CoRe project attempted to improve some of the known shortcomings of current working position development. It viewed the development process in terms of; the managed collaboration of a number of experts; traceable functional and HMI requirements which form the basis for evaluation and re-use; and a system development process based on the use and extension of industry standard methods. The process sought to provide traceability of requirements and design rationale through to structured evaluations, simultaneous maintenance of coherent functional and component views of the system, document management and generation (including hypertext), and support for re-use and consolidation, especially of requirements. The methods were used to develop a platform which was simultaneously a 'demonstration of concept' and the tool for the evaluation of HMI requirements and solutions for an en-route controller working position with complete basic functionality. Through the use of model-based development (in UML) and by partially de-coupling the specification and implementation processes, the CoRe project supported the processes of realising the same HMI on different platforms.
In particular, the CoRe project:
- consolidated and documented HMI requirements and illustrative specifications.
- produced a fully-documented HMI for demonstration and evaluation on a suitable platform.
- produced handbooks and training for the application of the CoRe process in the requirements capture, design and evaluation phases.

CWP DEVELOPMENT AS A SOURCE OF RISK: The development or modification of controller working positions is one of the most visible and critical activities in the upgrade of an ATM system. It is also one of the most difficult. For controllers, the CWP is both their working environment and the tool through which they exercise their professional skills. Consequently, changes to the CWP are a matter of considerable significance, potential sensitivity and an area in which acceptance of a system upgrade can be won or lost. Problems in CWP development, testing and acceptance have contributed to difficulties in R&D concept studies as well as the delays in introduction of a number of major systems upgrades in Europe. They also played a role in the $1.5 billion re-structuring of the US Advanced Automation System.

|
The objectives of the CoRe project were the improvement of the processes involved in the complete cycle of CWP development, from early R&D through to handover to industry for implementation.
|
|
|
Following analysis from a socio-technical perspective, the CoRe project proposed a view of the development process in terms of:
- the managed collaboration of a community of experts,
- traceable functional and HMI requirements which form the basis for evaluation and re-use, and
- an interactive system development process based on the use and extension of industry standard methods (e.g. UML, XML, etc).
|
|
|
The process sought to provide traceability of requirements and design rationale from conception through to structured evaluations. By means of an innovative GLUE model it simultaneously maintains coherent functional and component views of the system, provides document management and generation (MsWord, WinHelp and html formats), and support for re-use and consolidation - emphasising the role of requirements. These methods were used to develop a platform which is simultaneously a 'demonstration of concept' and the tool for the evaluation of HMI requirements and solutions for an en-route controller working position with complete basic functionality. As well as conference papers, the project produced a number of EATMP reports and EEC notes including guidance and exemplary material on HMI development and evaluation, the use and development of style guides and on the significance of requirements.

|
The CoRe project has produced deliverables at 3 levels:
- Guidance material in the form of reports on requirements management, style guides & HMI Evaluation.
- A development framework based on a linked set of 3 UML models - specification/functional, software/component, and the linking GLUE model.
- A basic, but high quality, en route HMI completely documented within the framework.
|
|
|
Expected long-term results are:
- a reduction in the risk of CWP development and better acceptance of CWP upgrades.
- a better liaison between specifying member states and supplying industry.
- a better visibility of potential requirements for industry.
- an improved re-use of both requirements and software in CWP development.
- a transfer of HMI between platforms.
- a systematic testing of HMI.
- a faster and more robust CWP development for R&D and real-time simulations.
|
|
|
In the short-term, the CoRe project has become the basis of the ECHOES activity providing:
- traceable HMI development to EEC study projects such as DOVE 3, Gate-to-Gate, or EVP.
- facilitating migration to the ACE platform.
- an integration of new ATM functions at the HMI interaction/presentation levels.
