Essential Question: What is your company-wide workflow?
•What have you promised to deliver your customer?
•What is the objective for each company, organization, department, team,
engineer?
•Use the objectives gathered to identify the data you need.
•Instrument for depth, not breadth.
•Codify alert states; automation is important.
