Non-Functional Requirements  Quick interaction  10 seconds or 7 keystrokes  Easy to learn  1 or 2 uses to familiarize  Privacy/Security  Improve overall patient flow  Extensible and dynamic

Assumptions/ LimitationAssumptions/ Limitation  Users will be hospital personal within the CCU unit and associated doctors  The network will be reliable  Display board will be viewable by personal within the CCU only

Market SurveyMarket Survey  Current Display within the CCU unit at Methodist West  Lacking electronic way to display and record information about current patients  Other departments within Hospital are receiving electronic systems while the CCU is not  Old “System”  Marker and Dry erase board  Hand-written notes

Risks and MitigationsRisks and Mitigations  Availability of client, or lack thereof.  Increased flexibility with meeting times  Privacy/Security issues  Coordinating with HIPPA privacy officer  Scope – Requirements creep  Sticking to the project schedule  Shelved software(Not used by intended users)  Usability testing
