EUC with HCI: Why It Matters
|The Collaboration Triangle whiteboard is available as an Adobe Acrobat PDF document optimized for
The triangle-shaped framework identifies the core elements of a work system: customers, products and services, business process, participants, information and technology. Surrounding these elements is the work system's environmentthe firm's business strategy, the IT infrastructure the work system shares with other work systems, and the organizational, competitive and cultural context in which the business operates. These three environmental elements provide resources and influence decision-making regarding the other six elements.
The team of IT and business professionals creating or re-engineering a system should use this whiteboard at the early stages of its development. Begin by creating a concise snapshot of the work system the information system will support (Checkpoint 1); then identify its problems and opportunities, clarifying which of these the project will and will not address (Checkpoint 2). After the IT team creates the initial plan for a new IT system, the team arrives at Checkpoint 3. The IT and business teams must now agree on the likely effects the proposed information system will have on the work system's operation and success. At each checkpoint, the triangle remains the same, but the questions differ. The IT and business members of the team should methodically consider the questions that go with each element and try to agree on the answers. An inability to agree is an important early warning that issues need to be resolved before investing additional time and effort in the project.
The framework does not guarantee the quality of the code or the completeness of the requirements, nor does it provide a full cost-benefit analysis of the new system. But it does increase the likelihood of genuine communication, realistic system requirements and reasonable expectations. Moreover, it improves the likelihood that the project will produce an information system that users will want to use, and from which the business can gain an effective and efficient work system without creating unexpected, unpleasant side effects along the way.
Three Critical Checkpoints
1. Create a Snapshot of the Work System
Work together to write a brief summary of the current work system by identifying its customers, products and services, business process, participants, information and technology, and relevant aspects of strategy, context and shared infrastructure. This snapshot helps resolve disagreements about work system scope. To keep this snapshot to one or two pages, the business process should be summarized in just a few steps.
2. Find Problems and Opportunities for Improvement
Use the questions above, which are organized into eight general work system goals such as "Please the Customers" and "Support the Firm's Strategy," to explore problems in the work system and find opportunities to improve it. Look for imbalances and misalignments between different elements: For example, do the customers really want the products and services? Can the participants perform the business process? The performance indicators shown can help evaluate the current process and spur thinking about possibilities for improvement.
3. Explore Effects of Proposed System Changes
After the IT team develops an initial plan, collaborate to answer the above questions. These questions help IT and business explore the positive and negative effects of the proposed information system and work system changes, especially as the effects propagate across the work system or even touch other work systems. Be sure to look for imbalances and misalignments between different elements that may be caused by the proposed changes.
