4. CSCI 4931 - Tool Overview 4 Tools: What & Why Any computer-based tools which attempt to support some aspect(s) of the software life-cycle Becomes more necessary as projects become more complex Help team members work together  central repository of artifacts produced  coordinate workers activities  implement process  give visibility to project status Automate some developers tasks  initially compilers and linkers, then editors, then debuggers,...  computer better than human for certain tedious tasks

5. CSCI 4931 - Tool Overview 5 Tools Integration Cooperation of tools to support (some aspect of) software development process. Set of integrated tools forms an integrated software engineering environment (ISEE). Implies that tools can:  communicate  share data  present information to the user in a coherent fashion

CSCI 4931 - Tool Overview 8 Requisite Pro Key Concepts Organizes Requirements in Repository Project is a requirements database and its related documents Documents can be product requirements, system requirements software and hardware specifications, user requirements, quality assurance Version Control lets you trace change by archiving projects User personal catalog, includes all projects relevant to a given user Multiple workspaces where distinct but interrelated work is done Multiple Views present information such as Status or Priority about Project, Document, or Requirements in graphics/ tables/outline tree Searching Capability Archiving through CM Tool Integrated with MS Word and MS Project Complete Requirements Traceability

9. CSCI 4931 - Tool Overview 9 ClearQuest Tool covering Change Request Management Used for Project Management and over entire lifecycle Addresses the single largest cost factor in software development: CHANGE Help an Organization manage change and track product defects over the entire life cycle Change Requests on any artifact created during the software development effort. CR tracked from input to disposition through the different states (submitted, assigned, opened, resolved, verified, postponed)

10. CSCI 4931 - Tool Overview 10 ClearQuest Key Features Workflow completely customizable Enable integration with existing source control and testing software Comprehensive Reporting capability gives entire visibility on project quality status with trends, aging and distribtion plots Web interface enables easy input of Change Request from remote team members Workers receive email notification of CRs states Associate Change Requests with evolving software development artifacts, across multiple products, versions, platforms and releases Scale up for Large Scale Development effort

11. CSCI 4931 - Tool Overview 11 Rose Tool supporting Visual Modeling Used mainly during Business Modeling, Requirements, Analysis and Design Implements the Unified Modeling Language (UML) notation Help an Organization communicate architectural decisions by cpaturing graphically the structure and interrelationships of the system Models are developed and managed over the entire lifecycle Main market share of UML tools
