Functional Requirements Status and Plans Christopher Neyman & Erik Johansson W. M. Keck Observatory Viswa Velur California Institute of Technology Keck NGAO Team Meeting #11 November 5, 2007 Videoconference

2 Outline Status of AO and laser FRD draft 0.3 Requirements management database tests Discussion

3 FRD AO section status Converted from Word document to Excel template for easier input into database Required functionality well documented Specification about 75% complete Traceability about 75% complete Text field references KAON, error budget, SRD, and/or ScRD sections. Version on Twiki and imported into database

4 FRD Laser section status Converted from Word to Excel database template Laser status –27 pages of requirement, ~ 200 requirements –Laser requirements, LTA, diagnostics & Laser service enclosure well done. Required functionality well documented Traceability 90% (by Nov. 5th) Rational 90% (by Nov. 5th) Version on TWiki and database (By Tuesday Nov. 6 CRN)

5 Selecting requirements database software Erik Johansson made a brief evaluation of a number of requirements management tools for use in the NGAO project (details in KAON) –DOORS (Telelogic) –Cross-Tie (Teledyne Brown Engineering) –CaliberRM (Borland) –OSRMT (open source) –Rational Requisite Pro (IBM) –RMTrak (RBC Product Development) –ARTS (Goda SW) –Contour (JAMA)

6 Selecting requirements database software Selected Contour by Jama Software, Inc., –web-based –multi-user tool –no client software required –easy to use and configurable to meet our needs –reasonably affordable –user community includes Intel, Amgen, and Lockheed-Martin, as well as smaller companies and startups

7 Testing requirements database software Received a 30 day trial multiple-user version of Contour –Expires Nov. 23 Installed at Keck –AO requirements imported from Excel template –Laser requirements imported from Excel template –See following screen shots on slides Global access through Keck fire wall –Make accounts and distribute passwords

8 Contour project explorer Organized by SEMP WBS Short name for easier searching Requirements document section: easier to organize final documents Rationale and traceability (just text field for now)

9 Contour requirements editor Rich text editor

10 Contour links and change history Attach documents or web links Link to other database elements Add notes and change notices Compare versions

11 Contour issues Need to decide on what to put into database or link to outside URL Automatic report generation –Issues with formatting Outside user testing –Access should be global (any IP) but requires two passwords (Contour and Keck internet) Make decision on Contour by November 23.

12 Requirements issues Forward and backward trace requires putting contents of ScRD, SRD into database Make decision on Contour by November 23 Gather input for AO & laser requirements version 2.0 –Release as design work completes at start of calendar 2008
