Requirements Elicitation

specify scenarios of use assemble and distribute customized questionnaires

questionnaires should be detailed but non-technical assumptions about users:

familiarity with computer / web-browser use address current practices in literature search

tools to use distribution over WWW, e-mail collection through WWW

avoid in-print questionnaires web-site hosting questionnaire forms

language? (single -- English, multi?)

Requirements Analysis

Many requirement analysis methodologies exist None is obviously better than the other Goal-based requirements analysis

questionnaire processing should lead to goal specification goal decomposition and refinement exception handling though scenario analysis result in operationalizable specifications

tools to use (under investigation) some requirements modeling tools exist few analysis tools (e.g., GBRAT)

Must capture functional and non-functional requirements
