Abstract:
In today’s increasingly globalised and complex economy that is flooded with data, taking decisions is a much more complex task. To help managers to tackle this challenge, we have developed a new multi-criteria performance management method that provides input for visual management and continuous improvement initiatives.
To improve, possible corrective strategies need to be identified and discussed. Visual analytical tools offer a way of presenting, justifying and explaining effectively and transparently decisions. Visual representation permits users to take in a large amount of information simultaneously as it maximises human capacity to perceive, understand and reason about complex data and situations. Visual representations promote high-quality human judgement with limited investment of the analysts’ time. Visual management has largely been used in production management in the forms of visual stream mapping, flow charts and area name boards. In this presentation, we show some visual techniques that can be coupled with multi-criteria decision methods. These include:
- GAIA plane, which represents multidimensional information in a two dimensional space whilst preserving as much of it as possible.
- Stacked bar charts, which allow the user to see the pros and cons of each action.
- Productivity graph that allows actions to be compared against each other.
These visual management tools are illustrated in a case study of innovation management and in another study evaluating energy sources in UK.
