1. PICTURE your design

2. Purpose : Functions & Content Functions the facilities that make the content of the ICT useful for relevant users and other ICT’s n verbs n input, output, process n make complete list n simplify with hierarchy n selective implementation (chapter 7 in OOA&D) Content the information, material, or virtual space that the ICT provides functions for n nouns n list elements n describe structure n show HCI representation n selective implementation (chapters 3, 4 & 5 in OOA&D)

3. Inspiration: Knowledge Transfer Exemplars n studying similar ICT, copying & imitating Metaphors n seeing your ICT as something else, breakthrough by breakdown Patterns n adapting general descriptions of problems and solutions to your ICT (chapters 1 & 2 in OOA&D)

4. Context: The Duality of Context l Application Domain: The context in which the ICT is used. l Problem Domain: The real-world or virtual context which defines the content of the ICT. l (Chapter 1 in OOA&D) Problem DomainApplication Domain ICT User

5. Context: Appreciating Context Application Domain n draw Rich Picture n outline scenarios n consider changes & training n consider services (chapters 3, 4 & 5 in OOA&D) Problem Domain n emphasize real world n consider changes n create virtual world n future user perspective (chapters 6, 7 & 8 in OOA&D)

6. Technology: Platform & Architecture l Platform l Client: user access l Server: network facility l Network: interaction l Which equipment? l Which software? l Which interfaces? l Architecture l Separation of Concerns l Information Hiding l (chapters 10, 12, 13 & 14 in OOA&D) UsersOther ICT’s HC-Interface Functions Content ICT

7. Users: People & Interactions People n user profiles n variations between users n determine user roles a user role determines a particular situation in which a user can interact with the ICT (chapter 6 in OOA&D) Interactions n identify use-cases n provide overview n describe selected ones a use-case describes the interaction pattern for a particular activation of the ICT’s functions

8. Users: Representation & Manipulation n How are the ICT’s content and functions represented on the HCI? n How can a user manipulate the ICT by activating functions? n How is the ICT divided into individual screen images? n How does the user navigate between the individual screen images? (chapter 8 in OOA&D)

9. Rationale: Why & How Why will users adopt the ICT and integrate it into their practices? n Appreciate their situation n Appreciate variations n Provide reasons How can the ICT be adopted by the users as part of their practices? n Appreciate changes in behavior, organisation & culture n Identify implementation risks n Outline initiatives (chapter 6 in OOA&D)

10. Evolution: Activities & Milestones n Identify activities what are we going to do? n Identify deliverables what are we going to produce? n Organize deliverables into milestones when are we going to deliver? (chapters 1 & 15 in OOA&D)
