Rich PictureUnderstanding of a situationRepresent the problem situationShould be self explanatoryCartoon-like representation that identifies

all the stakeholders, their relationships, concerns, and some of the structure underlying the work context.

Rich pictures are generally constructed by interviewing people. (iterative process)

5

Rich PictureApproach:– Elements of structure (refers to aspects of the work

context that are slow to change. These might be things such as the organizational hierarchy of a firm, geographic localities, physical equipment, and so on. Most important, it includes all the people who will use or could conceivably be affected by the introduction of the new system.)

– Elements of process (what is going on: refers to the transformations that occur in the process of the work. These

transformations might be part of a flow of goods, documents, or data).

6

Rich PictureConcerns is the most useful component, for

the purposes of this paper. Checklandmcalls them “issues.”

It captures more clearly the idea of a particular individual’s motivation for using the system. These different motivations give rise to the different perspectives each person has.

Root Definition CATWOE: WHO is doing WHAT for WHOM to whom are they ANSWERABLE What ASSUMPTION are being made In what ENVIRONMENT is this happening

Actor, Transformation, Client, Owner, Weltanschauung = raison d’etre, Evironment

17

CATWOEClients - (those who more or less directly benefit or suffer e.g. customers) from the machinations of the... Actors – Stakeholders, the players (individuals, groups, institutions and agencies), who perform the scenes, read and interpret the script, regulate, push and improvise. Identify and examine the role of local and institutional actors .... who undertake the..... Transformations - what processes, movements, conversions of X take place? What is the nature of the production and service transformations? What is the content and processes involved from ingredients to a sandwich, from mixed, varied data to information, from an idea to a performance concept or marketable product etc? What are the transformations that generate a product or a service? How are they achieved? How well are they performing?

18

CATWOEWeltanschauung or world-view - what is going on in the wider world that is influencing and shaping the "situation" and need for the system to adapt? Owners - the activity is ultimately "controlled" or paid for by owners or trustees. Who are they and what are their imperatives? How do they exercise their ownership power? Are their other stakeholders - who claim a stake and a right to be involved i.e. as legitimate quasi-owners. Ownership and the human activity occurs within an Environment - the trends, events and demands of the political, legal, economic, social, demographic, technological, ethical, competitive, natural environments provide the context for the situation and specific problem arena. We need to understand these.

Checkland :aircraft landing system (transformation) the incoming aircraft approaches

from a height and a distance. The goal is safe landing on the runway.

The actors are the pilots (human and auto), the clients - the passengers, crew, air traffic controllers, ground staff and people living under the runway.

The owners include the airline owners and their agents (the managers)

The environment: air lanes, traffic conditions and geographic features, regulation of landing and take-off slots at the airport, competition from other airports.

The weltanschauung may involve the rise in passenger traffic, competition between international airports, the airport-housing environment, high concern for safety and high technology operations.
