History/Value/Application
• History- SE- Products, Processes, People- use, fix– Pyramids/Greek/Romans/Ren/ British Train/ Model T/ WW I
tank– WW II- too much one person to detail design
• Value - % SE 10-15 knee of curve for cost and schedule control
• Applicable – Government- user need document – Commercial- Marketing / focus groups– International– Services
Bill Fournier
Definitions I• Systems- Products, Processes and People & boundaries, Purpose • 3 SE POVs – interdisciplinary, iterative, and recursive, way of thinking, feedback
loops, top down and bottom up • Requirements- Needs & technical requirements • CONOPS- plans how use system• Functions- verbs things systems must do to do mission• Physical Architecture/Design- nouns products decomposed which expected to meet
requirements and their interrelationships• Implementation- Build & Code development system• Integration- put subsystems and lower together• Verification- Prove by Objective Evidence that the requirement has been met with the
final configuration. TADI• Validation- Assess we meet what user needed• Test- method of assessing progress towards showing system works• Production- Make final hardware built and coded in quantity• Operation and Maintenance- use, maintain • Disposal- retire/recycle
Bill Fournier
Definitions II
• PM- Program/Project/Product Manager• Configuration Management – Plan, ID, control, status, audit the
technical baseline of system• Trade Studies- analyze alternatives trades • Technical /Design Reviews- decide if maturity worth going forward• Risk/Issues- things could go wrong / have gone wrong• TPMs- key early warning indicators of problems• Acquirer- manager the development contract for the stakeholder • Supplier- designs, builds/codes to meet contract(s)• SpE- SE like specialties with narrower focus
