Memo discussion question- Business Policy

An important type of report is the memo. 

Here’s info on the Memo Format: http://www.nku.edu/~fordmw/memo.htm

A few things to consider in a memo: 

Problem analysis or situation analysis
Summary of key findings as bullet points
Conclusion(s)
Recommendations for action
Supporting references and sources to justify the solution formulated

Can a memo be used to map out a thorough implementation plan on how to effectively manage people as well as development?
