A Principled Approach to IS Development in NEFIS

Drivers & EnablersBiz- driven IS/IT- enabledDrivers:

Business goals & objectives

Domain expert users

Enablers – IS specialists, Maths, Stats/Modellers, etc, etc

ON UML & Use Cases

UML is a language, A Visual Modelling Language

Not A Methodology

Used in a methodology to capture facets of a system:

Structures – static e.g. class model, …

Behaviour – dynamic, e.g. use cases, sequence, communication models, …

15.11.2004 Hamburg NEFIS WP5 GT & Tim R 17

ON UML & Use Cases

Use cases – widely used now++ Good for capturing user functional

requirements (FR)- - Not so good for NFRNFR: performance, scalability, fail-

safety, reliability, etc

Levels of use cases

Ref: Alistair Cockburn (writing effective use Cases, Addison-Wesley- 2001)

15.11.2004 Hamburg NEFIS WP5 GT & Tim R 19

Design scope Goal level

Enterprise (black-box) Very high summary

Enterprise (white-box) Summary

System (black-box) User goal

sea-level / whatSystem (white-box) <fish> Sub-function / how

(Below sea level)

Component Too low

Levels of Use Cases by goal /purpose

15.11.2004 Hamburg NEFIS WP5 GT & Tim R 20

From UML/use case to UI

To do yetGoal: bridge the semantic gapTransform ‘what’ use cases to

‘how’ nuts & boltsBuild a Mock-up or proto-type –

screen shots showing UI, display screen, reports, etc

Time-line (Draft) – WP3 / D9

Nov 2004 – time now – lot of work done

Dec 2004 – use cases 1 & 2 - Nefis

Jan 2005 – GUI–prototype – use case 1 & 2

Feb2005 – use cases 3 & 4 – MCPFE, FF

Mar 2005 – GUI–prototype – use case 3 & 4

Apr 2005 – Integrate all use cases/prototype, deliver!!

15.11.2004 Hamburg NEFIS WP5 GT & Tim R 22

Summary

A lot of spade work done alreadyMore work to be done stillUse cases are good for FR;Not quite suited for NFRNeed to talk to users in their language

– not in UML-speak or use case talk

But in terms of forms/display/reports
