What has been done -Developed initial Process Plan -Identified Issues in Preliminary Requirements Definition -Developed initial draft of Improved Understanding - Developed interactive mock-up

What remains to be done 1. Traceability matrix 2. Operationalize NFR to FR 3. Further validation of requirements At this point some validation was completed with 4 individuals ranging in age ~73 to 93 years old (caretakers & elderly). Input was incorporated.

What remains to be done 4. Identify more NFRs. 5. Define lists for vocabulary and categories 6. Extend prototype 7. UML diagrams 8. Implement our programs according to class diagram 25% Creeping Rate
