2. Slide 2: How to get out of a mess: Use the CORE methodology Cognitive Organization for Requirements Elicitation Scott M. Confer Joanna Wiebe Information Architect Information Architect Author contact: joanna.wiebe@orbitz.com 312.260.8274 Creative Commons license . Wiebe & Confer, 2007.
3. Slide 3: C O CORE overview R E Integrates two analytical methodologies: • Conceptual graphing (Gordon, Gill, Schmeier, 1993) • Collaborative soft systems inquiry framework (Checkland, 1981). 3
4. Slide 4: C O What is the CORE Method? R E • CORE – An emerging methodology and conceptual toolkit at Orbitz • Allows the IA to lead the team to – Clarify – Elicit – Iterate the initial vague requirements. 4
5. Slide 5: C O Advantages of the CORE method R E Centers on the user, drawn as a key actor in Rich Picture. Cross-disciplinary teams can work collaboratively to define quality requirements. Other advantages include: • Scalable for large or small projects • Is domain-agnostic • Rules-based formal grammar for cognitive graphing ensures a thorough approach • Based on empirically validated methods • Ecologically valid combination of two methods widely used in industry and business today Above all, CORE is a driver for innovation 5
6. Slide 6: C O CORE has seven steps R E Step 1: Unstructured situation Step 2: Rich Picture Step 3: Relevant systems Step 4: Conceptual Graph Structures (CGS) Step 5: Preliminary requirements Step 6: Requirements consensus Step 7: Translation to Information Architecture 6
7. Slide 7: C O The scenario R E Final details of the contract with the third party had not yet been resolved, one reason that the requirements were not complete at kickoff … Sound familiar? 7
8. Slide 8: C O So, you find yourself needing better requirements? R E • The IA didn’t have a formal organizational method for requirements development. • The ‘flat’ organizational structure at Orbitz demanded team consensus for the project to move forward What to do next? 8
9. Slide 9: C O What to do? R E Add structure! 9
10. Slide 10: C O Step 1: The Unstructured Situation R E In an unstructured situation, “…human perceptions, behavior or actions seemed to be the dominating factors…goals, objectives and even interpretation of events are all problematic.” (Naughton, 2005) Also known as the “MessTM” in soft systems 10
11. Slide 11: C O Some attributes of a requirements “mess” R E • • Too little, incomplete, or Undefined or implicit features missing: • Featuritis – User research • Speed to market is the driver – Functional requirements • “We don’t need no requirements!” – Use cases • “Requirements” are: – Voluminous (i.e. have Featuritis) • Magically coordinate with – Solutions-focused other projects / – Vague dependencies – Disorganized – Missing – Conflicting – Interdependent – Not prioritized (or all=HIGH) 11
12. Slide 12: C O Some attributes of requirements with “quality” R E • • Correct Verifiable • • Unambiguous Modifiable • • Complete Traceable • • Consistent Understandable • Prioritized for importance and stability Reference: Leffingwell, D. and Widrig D. (2000). Managing Software Requirements - a Unified Approach 12
13. Slide 13: C O To structure an “unstructured situation” . . . R E 1. Identify key roles 1. Form your team – investigator – subject matter expert 2. Do the research – client – What is this thing? – problem-owner – What’s happening? – problem-solver – What to do? (one person may wear many hats) – Where is it? – Where can I find out more? (more question probes, next slide) 13
14. Slide 14: C O Question probes for primary research R E Where can I What is this What’s What to do? Where is it? find out thing? happening? more? What is this thing? What’s happening?

If they want to book non -event travel, do they have to log out first ?
16. Slide 16: C O Case study example: Rich Picture R E A Rich Picture is Checkland’s term for a visual capture of: • Structure • Function • Process • Environment. The IA worked from her raw interview notes, whiteboard sketches and assumptions, to create the Rich Picture, using Visio. Drawing the picture is a way to methodically walk through some or all of key aspects of the project. 16

18. Slide 18: C O Rich Picture elements R E 1. Key actors 1. “Hard” or “soft” information – Hard information: verifiable data and knowledge 2. Structure of actor interactions – Soft information: feelings, perceptions, opinions, values—often key to project success or failure 3. New Features 2. Types of requirements: – Integration with existing ones – functional, data, content, creative, data safety, testing performance, user interface, localization, 4. Process flow technical, financial, temporal, managerial 5. Environmental factors 3. Tasks involved in understanding each requirement type 1 THIRD PARTY EVENT SITE HARD INFO : Event registration and approvals workflow process § Create participant types, manage participant lists etc § Travelport for Business Global view of all event activity costs, benefits , § Preparing , u
