g the measurement of independent and dependent variables and the experimental design. Finally this paper concludes with the significance of this proposed study to both researchers and practioners.

Theory and Hypothesis.

The research model developed for this proposed study is shown in figure 1. The figure illustrates that DID enhances decision making. The effect of DID is more pronounced when the task is less time critical where the decision makers are not pressed for time and the effect of DID is limited when the task is time critical. The hypotheses supported by theory are developed below.

Dynamic Interactive Display

Businesses today are commonly using Dashboards, which is a combination of visualization tools that provide summarized and details reports of current status and alerts and creates situational awareness. The array of visualization tools that available today includes Tree Maps, [23], Node-Link diagram /Network diagram[24], Parallel coordinate Graph [25], Spark lines- Integrates text, and chart [26],Motion chart[27]. The present study focuses on visualization tools that provide dynamic and interactive display (DID) because in the recent time there has been staggering advances in visualization tools that are interactive and dynamic to support taking decisions and solving information-intensive problems in business. The DID chosen for this study is Google’s Motion Chart, which is a flash based visualization tool that delivers dynamic chart with high level of interactivity for multidimensional data[28].

Motion charts are dynamic. The graph is said to dynamic when the graph consists of series of single frames, each showing incremental changes in the position, brightness, shape, color of the variables; shown in a sequence which give the illusion of movement[29, 30]. Graph Dynamism consist of two types of change : position or form [31, 32]. Translation change refers to change in position (from one location to another) and transformation change refers to the change in form ( in size, shape, color, brightness)[33]. Motion chart reflect both translation change and transformation change. It is dynamic as it has several indicators which show incremental change in color, location and shape over time.

Graphical excellence consists of complex ideas communicated with clarity, precision and efficiency and are accurately perceived [14]. Animations are often not clear and complex or efficient ( too fast) to be accurately perceived and judicious use of interactivity may overcome this disadvantage [17]. Motion Chart provide high level of interactivity (i.e., the extent to which users can manipulate and transform the form and content of the graph in real time[34]. Interactivity is achieved when the users can control the speed of animation and can view and review, stop and start, can transform (change the way representation is rendered, such as zooming, panning or resizing), or manipulate (control the parameters during the process of image generation, i.e. filtering, visually encoding the variables based on color, shape).
