Project Management ObjectivesProject Management Objectives

Manage software growth On site Level 1 support provided at EEC Regular delivery cycle, and Level 2 support Regression and automated testing

Exploit existing software base Develop software to be reusable Constant improvement and redesign

Remain responsive, look for feedback Short development cycle Regular intermediate deliveries, prototypes

Development LifecycleDevelopment Lifecycle Premise: Requirements will change Task driven incremental software development

Project plan Initial design and test plan Initial development Create test scripts Re-plan Review design (software and tests) Software re-code and re-factoring Regression test Update documentation

Incremental Delivery

Client Feedback

Relationship with ESCAPERelationship with ESCAPE Complementary platforms

ACE hi fidelity – but long development cycle eDEP low fidelity – but functional, short development cycle

Benefits to ESCAPE Early evaluation of concept Small scale trials Iterative approach to concept development Results fed into ACE component development

ACE/eDEP Gateway: AEG Hi fidelity calculations from ACE Prototyped HMI using eDEP Interoperable components – TCT server

Support to ESCAPE ACE lifecycle upgrades Wrapping eDEP components using ACE API

Project SynergyProject Synergy Shared, open software base enables

Clients to trust software Projects to share common costs Produce a very wide functional capability

Core software and thin projects Core software developed once Configured for different clients Projects contribute to core development eDEP community benefits

Examples: STORIA, RST, TCT, CIMACT

IssuesIssues

How to keep software in step Multiple projects sharing same code base Careful planning Synchronisation of clients’ requirements Review of client timescales and objectives

Management of diverse requirements Rapid prototyping Medium scale simulation Certificated training Operational systems

ConclusionConclusion eDEP works because clients contribute

Development needs client feedback Progress is easily reported back to clients Possibility to re-use software across different projects

Rapid concept development possible Software reuse across different projects User group can provide visibility for

New components Additional functionality Supplementary tools Gateways to third party software
