Information mapping


Information mapping is a research-based method for writing clear and user focused information, based on the audience's needs and the purpose of the information. The method is applied primarily to designing and developing business and technical communications. It is used as a content standard within organizations throughout the world.

Overview of the information mapping method

The information mapping method is a research-based methodology used to analyze, organize and present information based on an audience's needs and the purpose of the information. The method applies to all subject matter and media technology. Information mapping has close ties to information visualization, information architecture, graphic design, information design, data analysis, experience design, graphic user interface design, and knowledge management systems.

Components of the method

Information mapping provides a number of tools for analyzing, organizing and presenting information.

Information types

Some of Robert E. Horn's best-known work was his development of the theory of information types. Horn identified six types of information that account for nearly all the content of business and technical communications. The types categorize elements according to their purpose for the audience:
Information TypeDescription
ProcedureA set of steps an individual performs to complete a single task
ProcessA series of events, stages or phases that occurs over time and has a specific outcome
PrincipleA statement designed to dictate, guide or require behavior
ConceptA class or group of things that share a critical set of attributes
StructureA description or depiction of anything that has parts or boundaries
FactA statement that is assumed to be true

Research-based principles

The information mapping method proposes six principles for organizing information so that it is easy to access, understand, and remember:
PrincipleDescription
ChunkingBreak up information into small, manageable units
RelevanceLimit each unit of information to a single topic
LabelingLabel each unit of information in a way that identifies its contents
ConsistencyBe consistent in use of terminology as well as in organizing, formatting and sequencing information
Accessible detailOrganize and structure information so those who need detail can access it easily, while those who don't can easily skip it
Integrated graphicsUse graphics within the text to clarify, emphasize and add dimension

Units of information

Documents written according to information mapping have a modular structure. They consist of clearly outlined information units that take into account how much information a reader is able to assimilate.
There is an essential difference between an information unit and the traditional text paragraph. A block is limited to a single topic and consists of a single type of information. Blocks are grouped into maps, and each map consists only of relevant blocks. The hierarchical approach to structuring information greatly facilitates electronic control of content via content management systems and knowledge management systems.

Advantages of information mapping

The information mapping method offers advantages to writers and readers, as well as to an entire organization.

Advantages for writers

Information mapping offers these advantages for writers:
Information mapping offers these advantages for readers:
Also an entire organization can benefit from using a content standard like information mapping if the method is used with the following objectives in mind:
Information mapping was developed in the late 20th century by Robert E. Horn, a researcher in the cognitive and behavioral sciences. Horn was interested in the visual presentation of information to improve accessibility, comprehension, and performance. Horn's development of the information mapping method has won him recognition from the International Society for Performance Improvement and the Association for Computing Machinery.

Review of research

Many independent studies have confirmed that applying the information mapping method to business and technical communications results in quicker, easier access to information, improved comprehension, and enhanced performance. It also facilitates repurposing for publication in different formats.
Doubts have been raised over the strength of the research Horn uses to justify some of his principles. For instance, his chunking principle requires lists, paragraphs, subsections, and sections in a document to contain no more than 7±2 chunks of information. Horn does not state where he got this principle, but an Information Mapping website stated that the principle is "based on George A. Miller's 1956 research". Miller did write a paper in 1956 called "The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information", but its relevance to writing is tenuous. Miller himself said that his research had nothing to do with writing. Insisting that lists, paragraphs, subsections, and sections throughout a document contain no more than 7±2 chunks of information paradoxically assumes that the size of what is not read in a document can influence a reader's ability to comprehend what they do read.
