- Scenario Capstone project Goal Statement: Our goal is to improve the overall mental health status of veterans of the Canadian Armed Forces and RCMP by up to 80% for those struggling with mental health challenges by facilitating real-time accessibility to a peer support platform utilizing a mobile app to fill the gap that currently exists when veterans are awaiting appointments for psychological supports that are currently funded by Veterans Affairs of Canada. We aim to reduce the strain on the general health system due to the repeated appointments with a veteran's primary care practitioner to inquire about further mental health resources and to improve a veterans quality of life while they are adjusting to civilian life in between their federally funded psychological supports.

There are never enough resources to get everything done." Backlogs build over time. Sacred cow projects get included in the selection system. Projects proposed from people who have left the airline stil reside in the project portfolio. Non-value-added projects somehow make their way into the project portfolio. Soon the queue gets longer. With everyone in IT working on too many projects concurrently, project completion and productivity are slow. Which Projects Remain? To cut the number of projects, the steering committee used a weighting scheme that reflected the airline's priorities, which were: fly safe, generate revenue, reduce costs, and customer service. The weighting scheme easily weeded out the fluff. Coady noted that "by the time you get to the 20s the margin of differentiation gets narrower and narrower." Of the remaining projects, project sponsors had to have solid justification why their project is important.

Rescue practitioner Sipho Sono of Opis Advisory said one meeting was with the airline's creditors and the other with unions and representatives of non-unionised employees. He said he was satisfied with the process so far. "The next steps will be setting up several meetings with the various committees established. More details will be provided as the business rescue process unfolds," said Sono.
