Core featuresUse-Case DrivenArchitecture-CentricIterative and IncrementalOrganisation: Phases & Workflows

12-13.12.2002 e-Science Project Managers Forum

Use-Case Driven

Capture functional requirements‘gives a user a result of value’Drives development process Design Build Test

12-13.12.2002 e-Science Project Managers Forum

Architecture-Centric‘common vision’Most important model elementsDifferent views

Architectural baseline (‘small skinny system’)

12-13.12.2002 e-Science Project Managers Forum

Iterative and Incremental

Iterations: ‘mini-projects’Use-case selection: Most important risks

Incremental development

Science ProblemsFocus on problems to be solvedWhat is difficult?What takes too long?What is exciting?

Domain model

Hindsight

Start with ScienceWork packages contra UP spirit Many concerns vs ONE

Domain model not especially useful

12-13.12.2002 e-Science Project Managers Forum

What is/was missing?Hire Software Architect *from (before) start* VISION

Case studies in UP for e-Science/academic projectsIterative planning processMetrics milestones/deliverables setting

Methods of collaborative working(in distributed team)

12-13.12.2002 e-Science Project Managers Forum

What is good!

Acceptance of UP But still insisting on wp-based metrics

Risk-willing (vs risk-averse)Academics are used to: Incremental development Refactoring

12-13.12.2002 e-Science Project Managers Forum

Next steps

Write-up AstroGrid as case studyInvestigate planning approaches (system dynamics approach?)

Better marriage of work package structure & single deliverableDevelop/promote believable metrics
