MicroHealth, limit bullets, answer the
requirement with what MicroHealth will do 
to satisfy the requirement, the technical 
approach with innovation for efficiency, 
productivity, quality and measurable 
outcomes, the industry standard that 
methodology is based on if applicable, 
detail the workflow or steps to accomplish 
the requirement with labor categories that 
will do those tasks in that workflow, 
reference reputable research like gartner, 
forrester, IDC, Deloitte, Accenture etc 
with measures of success and substantiation

like maybe, could be, should, possible be definitive in your language and confident.
