Output Design IssuesOutput Design Issue Description

Purpose  What is the intended use or purpose of the output? 

Primary User(s)  Who will be the primary users of the output? 

Frequency  How often will the output need to be generated? 

Delivery Point  Where will the output be used? 

Human-Machine Boundaries

 What are  the points  in  the system where  the end user must  (or can) interact with the system? Content  What information must be delivered by the output? 

Media  In what form will the output be delivered? 

Format  How will the content of the output be displayed and formatted? 

Controls  What controls are necessary to limit access to the output?

Output Design GuidelinesExplanation

Clear and meaningful titles Titles should clearly and specifically describe the content and use of the output. 

Relevant content Only  the  information necessary  to use  the output should be  included and the presentation should be such that the output can be used without modification. 

Balanced Layout Adequate  spacing  and margining  should  be  used  to  allow  for  a  balanced  or  symmetrical presentation of the output. 

Clear Navigation The output  should make navigation and  location easy  for  the end user. This  includes  the use of indicators such as page numbers, section numbers, and end of section or sequence indicators. 

Use of highlighting and color Techniques for emphasizing a particular data value, exception, or section should be used to make it easier for the end user to focus on important items contained within the output. Such techniques include color or  intensity differences, multiple size fonts, underlining, bolding or italicizing, and capitalization. 

Appropriate formatting of text elements Text should be presented using mixed upper and lower case with conventional punctuation. Paragraphs  should  be  double-spaced  or  separated  by  a  blank  line  when  single-spaced. Abbreviation and acronyms should be commonly understood or clearly defined on first use. Words should not be hyphenated between lines. 

Appropriate formatting of tabular elements All  columns  and  rows  should  be  clearly  and  meaningfully  labeled.  All  labels  should  be repeated when data extends beyond a single page or screen. Columns and rows should be sorted in a meaningful order. All numerical data should be right-justified with decimal points aligned and all  text data should be left-justified using relatively short  line  lengths (30 to 40 characters).
