Maps, Matrices & Models
The LEADing Practice Artefacts are a part of the LEAD Architecture Description and consist of artefacts in terms of both maps, matrices and models that capture the meta objects of the enterprise. They are instrumental and an essential part of the supporting frameworks, methods and approaches. Each of these support a particular stakeholder concern to enable value identification, creation, and realization in achieving the outlined needs and wants. For this the LEAD artefacts identifies the stakeholders relevant, their concerns in a pain chain and their expectations in a goal chain. Creating the fundamental architecturally significant aspects, which are related to the identified and relevant objects e.g. goal, process or system-of-interest. As with all Architecture Descriptions and their architecture rational, correspondence rules and architecture views and viewpoints, each of these artefacts, built as artefacts to support a particular need and want. For a full list of the LEADing Practice Meta Objects and their descriptions, please see the following document LEAD Meta Object Taxonomy.

A LEADing Practice Map is an accurate list and representation of the decomposed and/or composed objects. A map is often in the form of a list that can be in a simple row as well as a catalog, and has the purpose of building an inventory or index list of the objects that are to be either decomposed and/or composed in the business layer, application layer and technology layer.
A LEADing Practice Matrix is a representation that accurately shows the relationship between specific decomposed and composed objects. The core idea of a matrix is that it typically consists of aspects of one idea each in a list of row, another idea as a set of columns and a third as the cross product between the rows and columns. This allows the matrix to relate the unfamiliar to the familiar objects in the different layers (composition) usually through the form of a diagram, a table or a chart (e.g. rows and columns), thereby outlining direct connection points and showing a common pattern of the objects.
A LEADing Practice Model is a representation that graphically shows the relationship and the interconnection of specific composed objects and complies with a specific set of rules for what the graphical components mean and how they are connect. The key ideal of a model is that it is a graphical representation, an illustration, of a composition of information intended to represent an aspect of an enterprise e.g. business, application and/or technology, using a specific set of rules, which express a logic or grammar. Based on already acquired information from either a map or a matrix (or both), a model is usually crafted to enable complex information to be communicated more easily to stakeholders, management and leadership within their domain through the use of a more detailed, graphical illustration and/or depiction.
The Importance of Fully Integrated Artefacts
Fully integrated and standardized artefacts enables the practitioner to work and model with the objects throughout all the architectural layers (business, application and technology) and this is one of the strengths of the LEAD concept. Not only are the objects governed by its connection modelling rules, but how and where the artefacts interlink and share common objects is defined and standardized. Therefore a matrix is the continuity of and interconnection between a map (a representation of decomposed and/or composed objects) and a model (a representation of interconnected and related objects). The maps, matrices and models are therefore used in the decomposition and composition work (within and throughout the layers). Using spreadsheets to manage this highly connected information defeats the value and richness of the approach. It is akin to asking your finance department to use spreadsheets to manage your general ledger or track your customers and suppliers when you chose to use a spreadsheet to keep details about the internal workings of your business and how all the elements that are used to create value and generate costs are connected. The map (which list the objects in order to capture the decomposed objects) is vital as well as the matrix (which composes in terms of relating specific objects together) and the model (which graphically represent the decomposed and composed objects) are both critical in integrating and standardizing the artefacts and tools of the LEADing practitioner. Furthermore is it an essential part of supporting as well as integrating and standardizing the practitioners Way of Thinking, Working and Modelling. At last but not least, it changes the Enterprise Architecture and Enterprise Modelling Governance as well as the Continuous Improvement of the artefacts. Bringing an organization that uses the LEADing Practice artefacts to the highest maturity possible of working not only documented (level 3) or managed (level 4) but enabling optimization, governance and continuous improvement (level 5).
