Information Engineering (IE) or Information Engineering Methodology (IEM) is an approach to designing and developing information systems. It has a somewhat chequered history that follows two very distinct threads. It is said to have originated in Australia between 1976 and 1980, and appears first in the literature in 1981 in the Savant Institute publication 'Information Engineering' by James Martin and Clive Finkelstein. Martin and Finkelstein's ways parted soon after and from that time separate forms of Information Engineering were developed in Australia by Clive Finkelstein and his company, Information Engineering Services Pty Ltd, and in the UK, Europe and USA by James Martin and his company James Martin Associates. The Martin version gained much wider currency in the 1980s and 1990s, aided by his position as a major guru and prolific author in the IT world. 1976 (MCMLXXVI) was a leap year starting on Thursday. ... 1980 (MCMLXXX) was a leap year starting on Tuesday. ... Dr. James Martin is a consultant and author, has been called the guru of the information age, and was nominated for a Pulitzer prize for his book, The Wired Society: A Challenge for Tomorrow. ... Clive Finkelstein is acknowledged worldwide as the Father of Information Engineering (IE), having developed its concepts from 1976 _ 1980 based on original work carried out by him to bridge from strategic business planning to information systems. ...



Information Engineering first provided data analysis and database design techniques that could be used by database administrators (DBA’s) and by systems analysts to develop database designs and systems based on an understanding of the operational processing needs of organizations for the 1980's. Database design is the process of producing a detailed data model of a database. ... A database administrator (DBA) is a person who is responsible for the environmental aspects of a database. ... Systems analysis is the science dealing with analysis of complex, large scale systems and the interactions within those systems. ...

After 1980 the Finkelstein thread evolved into the DP-driven variant of IE. From 1983 till 1986 IE evolved further into the business-driven variant of IE, which is designed for today's rapid change environment. 1983 (MCMLXXXIII) was a common year starting on Saturday of the Gregorian calendar. ... 1986 (MCMLXXXVI) was a common year starting on Wednesday of the Gregorian calendar. ...

The Martin thread was strategy-driven from the outset and from 1983 was focused on the possibility of automating the development process through the provision of rigorous techniques for business description that could be used to populate a data dictionary or encyclopedia that could in turn be used as source material for code generation. The Martin methodology provided a foundation for the CASE tool industry. Martin himself had significant stakes in at least four CASE tool vendors - InTech (Excelerator), Higher Order Software, KnowledgeWare, originally Database Design Inc, (Information Engineering Workbench) and James Martin Associates, originally DMW and now Headstrong (the original designers of the Texas Instruments' Information Engineering Facility and the principal developers of the methodology). At the end of the 1980s and early 1990s the Martin thread incorporated Rapid Application Development (RAD) and Business Process Re-engineering (BPR) and soon after also entered the object oriented field.

What is Information Engineering?

Information Engineering Methodology is a rigorous architectural approach to planning, analysing, designing, and implementing applications within an enterprise. It enables an enterprise to maximize its resources, including capital, people and information systems, to support the achievement of its business vision. It is defined as: "An integrated and evolutionary set of tasks and techniques that enhance business communication throughout an enterprise enabling it to develop people, procedures and systems to achieve its vision". Information Engineering has many purposes, including organisation planning, business re-engineering, application development, information systems planning and systems re-engineering.

The Variants of Information Engineering

There are two variants of Information Engineering (IE). These are called the DP-driven variant and the business-driven variant.

DP-Driven Variant of IE The DP-driven variant of Information Engineering was designed to enable IS Departments to develop information systems that satisfied the information needs of the 1980's - which was largely a DP-driven development environment. Most of the Computer-Aided Software Engineering (CASE) tools available today support this DP-driven variant of IE.

Business-Driven Variant of IE From 1983 - 1986 Clive Finkelstein extended IE strongly into strategic business planning and developed the business-driven variant of Information Engineering. This variant is designed for rapid change in the client/server, object-oriented environment of the business-driven 1990's. Business-driven IE is documented in the later books by Clive Finkelstein.

Stages in the Information Engineering

Information Strategy Planning The fundamental objective of Information Strategy Planning (ISP) is to develop a plan for implementing business systems to support business needs.

Outline Business Area Analysis The OBAA answers a range of questions related to implementation of a business area. Select tasks to include in a particular project that provide support for business decisions and objectives. Specific information needs and priorities for the business area are needed.

Detailed Business Area Analysis The purpose of a DBAA project is to provide detailed models as a solid basis for system design. The methodology helps find the right answers to the right questions. Applying the methodology is never an end in itself.

Business System Design The purpose of a Business System Design project is to specify all aspects of a system that are relevant to its users, in preparation for the technical design, construction, and installation of one or more closely related databases and systems. The key tasks are therefore structured to produce unambiguous consistent specifications, with the volume of detail necessary to make planning and technical design decisions.

Technical Design A Technical Design project prepares an implementation area for construction and installation. The key tasks are structured to produce a system and database that meet the user's acceptance criteria and are technically sound.

Construction The objective of the Construction stage is to produce a system, as defined in the technical specification, on time and within budget. The system should be of an acceptable quality, and contain all necessary operating and user procedures. The task is complete when the acceptance criteria for the business system are met.

Transition Transition is defined as the period during which newly developed procedures gradually replace or are interfaced with existing procedures. The execution of a Transition project obviously demands a thorough understanding of both the system to be installed and the systems to be replaced.


Some technigues that are used during an IE project are:

Entity analysis identifies all the things that the enterprise may want to hold data about. The analysis classifies all of the things into different entity types, revealing how they relate to each other. Which is being described in the entity model.

Function analysis and process dependency takes a function (a major business activity) of the enterprise and breaks it down into elementary business processes. From this, two diagrams are prepared: the process decomposition diagram, which shows the breakdown of a business function, and the process dependency diagram, which shows the interdependencies of business processes.

Process logic analysis describes the sequences of actions carried out by a business process and shows which data are used by each action.

Entity type lifecycle analysis describes the significant business changes to entities and confirm that processes have been modelled to effect these changes

Matrix cross-checking creates cross-references between data objects and processes to verify that they are necessary and complete.

Normalization provides a formal means of confirming the correctness of the entity model.

Cluster analysis helps define the scope of design areas for proposed business systems.

Data flow and data analysis makes a comparison possible between the business area models and the systems currently supporting this area, these current systems are analyzed using data flow and data analysis techniques.

Software Tools Supporting Information Engineering

Information Engineering Facility (IEF) from Texas Instruments Software. This was subsequently sold to Sterling Software and then to Computer Associates. It still exists, in an evolved form within the Advantage suite. As of 2006 referred to as ALL:Fusion Gen, capable of generating J2EE and JAVA web applications in addition to legacy client/server and mainframe platforms. This article needs to be cleaned up to conform to a higher standard of quality. ...

Information Engineering Workbench (IEW) Later renamed to Application Development Workbench (ADW) from KnowledgeWare. Knowledgeware was also acquired by Sterling Software. The product no longer exists. This article or section does not cite its references or sources. ...

Others included Bachman's Data Analyst, Excelerator and others. See Computer-aided software engineering for more info. ERWin CASE tool on Windows 2000 Computer-aided software engineering (CASE) is the use of software tools to assist in the development and maintenance of software. ...

The business-driven variant of IE is supported fully by Visible Advantage, an Integrated CASE (I-CASE) tool and by Visible Advisor, a hypermedia Methodology product.

Visio provides diagramming support to some of the Martin techniques.
