1.1 THELAYOUT OF MEMOS
Because the memo form was developed to save time，the formality of an inside address，salutation，and complimentary closing is omitted.Most companies have memo stationery with a preprinted heading.Different companies，however，may use different formats and even within a company，different departments may write memos in different formats.Nevertheless，a memo should include the following information：
●Who is the memo to？
●Who is the memo from？
●What is the subject of the memo？
●What is the date？
These should be positioned as shown in the following examples.

The To and From.In the To and From sections，the business title of each person is often included，particularly when the memo is being sent to a person whose office is in another city.In the To section，a courtesy title—Miss，Mrs.，Ms.，Mr.，Dr.—is often included.However，in the From section，the writer's choice of whether to use a courtesy title or not depends upon the degree of formality that he decides to use.
The memo forms used in large companies may also include other details to facilitate communication among co-workers in various departments and branches of the firm.

The writer's job title，for example，“job manager”may be included.Some firms insist on the job title as house-style.On its own，without a personal name，the job title would be very formal.Added to a name，it gives a slight touch of formality.In order of formality the possibilities are：
●Office Manager（very formal）
●Mr.Smith，office manager（formal）
●Mr.Peter Smith，office manager（rather less formal）
●Mr.Peter Smith（average formality）
●Mr.Peter Smith，office manager（average formality）
●Peter Smith（slightly informal）
●Peter，office manager（informal）
●Peter（very informal）
The Subject and Date.The beginning of a memo is usually the subject line.It is a brief statement telling what the memo is about and helps the reader to prepare for the contents.
The subject line is not a complete sentence but rather a concise phrase that gives the reader the topic plus a focus.Some companies prefer to have the subject line typed in all caps.
One-word subject lines don't communicate effectively，as in the following flawed example.
Subject：Stationery
An improved subject line would read as follows：
Subject：Ordering of Company-Headed Stationery
This subject gives the topic（Company-Headed Stationery）plus a focus（ordering）.
Complete dates are just as important on memos as they are on letters.Dates are necessary for future reference to prevent miscommunication.
The Message.Memos solve problems either by informing the reader about new information，like policy changes，price increases，etc.，or by persuading the reader to take an action，such as attending a meeting，or changing a current production procedure.Regardless of the specific goal，memos are most effective when they connect the purpose of the writer with the interests and needs of the reader.
