What do you see as the difference in writing strategy for a report vs. memo vs. a letter?

Memo is an inter office communication document normally addressed by one department to another for information or action purpose. Letter is often an external party document which the officer or company manager addresses to an outside party, purpose being information or seeking urgent action for pending issues or reminders, etc. On the hand, report is an official comprehensive document prepared by an expert with background, situation analysis, problem statement/ events occurence, possible solutions and actions taken, recommendations and conclusion. There are different types of reports like quality report, non conformance report, safety report, manpower report, progress progress report, audit report, factory test report, market research report, financial reports

Thanks for the invitation.

I agree with some of the above postings.

Thanks for the invitation. Memo is written for communication within an organization. Report is written about accomplishments, research, etc. while a letter is usually written to a person outside an organization.

Thank you for the invitation

I agree on the answer colleagues

Memo is usually an internal documment, ment to remind specific facts; the name of the company, logo, etc can be missing; the style should be concise, precise and brief

Letter is a more formal documment, very often external, therefore the shape and the content of the documment should be more detailed and literal

Report is a documment issued by a specialist, very often for the top management. The content should be very specific, as detailes as possible (minor detailed may be missing, depending on the case) and should offer a clear picture of a specific matter, as seen by the author; may contain recommendations or estimations; style shoud be concise and precise; from case to case, it can be not very official, yet not informal

There is difference in the subject, importance and purpose. These three cases of  writing used in any company or organization Three types of writing arranged to organize company work and its activities internally and externally. Each type used for a certain purpose as :

1- Report is used normally in the important case prepared from the head of section or department or expert to describe case or analysis of the situation in the work and market or some time using in big problem, event or challenge in the market such as Competition & Market Analysis report, Progress report for site works, Audit report , Financial report --- etc.

2- Memos is internal correspondence as office documents to communicate between department or section to other department or section or between the subordinates and the Boss or from the Head Management to all employees.

3- Letter is Formal correspondence used internally and externally but mostly used for the external correspondence with other companies and organizations for the offers submission, negotiation start, Contract execution, Pending work , Outstanding payments and actions required for the problem treatment 

Thanks for invitation,

Memo : Is an inter-office letter which is addressed from the department to another department inside the organization.

Letter: Is a means of communication used between two different organizations.

Report: Is a means of analysis' output for specific data / information in a form of figures, percentages or digrams  

Thanks

I fully agree with the answer given by colleague Khalid Halim

All of these are source of communication but all of these are addressed differently from one to the other to serve their respective purpose

Memo : Is written to deliver a common message or brief update or to notify team members and is announced publicly  

Letter : Is written to an individual focusing on specific individual or considering specific individual and this doesn't go public

Strategy : Its a plan, a process which needs explanation and discussions at common place for those related to be part of it

Regards

Strategy is when you come with a process on how best you get the job done. When writing a strategy for report you are recommending / summarizing what course of action that should betaken to avoid a certain problem in the future.

Memo is a general notice of strategy that is to notify people of action that needs to be taken or strategy to be taken in general 

Letter is more personal recommendation about a strategy that need s to be taken delivered to the individual privately.

Basic difference

Business memos are internal documents sent to employees to convey information about the company, while business letters are external communiqués, often related to sales activities or customer needs or to query a vendor or government agency. The formatting is different for both.
