Data speaks thousand words and Charts speak more than that! Are you one among them who are interested in constructing fascinating charts, and do you believe management decisions can be done easily with few interpretation of charts, then you can spend some “time” to read this…
Any activity/motion/process in this world not only consumes movement or energy, but they also consume time. Traditionally we have been ignoring time, time and again. Unless we work on trend or control charts we don’t represent time, instead we work to represent mostly the volume or results in our charts without giving time scale to it. No result can be produced without time and time always moves ahead and never comes back. Many a time it’s not a standard practice for us to attach or provide details of time period of data along with any chart, and we require some manger with common sense to ask the question, which time period it represents and what is the trend in this time period. If we look at any output in chart, it’s important to ask the time it consumed/it represents in a chart. A better way of representing is, every chart shall have time angle to it (only in trend/control charts and some or with timeline). Today we miss time as an indicator in our charts, and occasionally people represent time in
Chart title. Why it’s so important? It’s important to understand the movement of energy in a space along with time space, to make a decision which is applicable to the nearest timeline. It helps us to understand the seasonal variation (time space) of outcome and the current condition/latest time period of data. Our decisions are not made for past, they are for future and in order to ensure, it’s important to understand that are we looking at something which is nearer, if not how much old the data in time space, can we rely on it, all these are possible only with understanding of time space.
For example, we take
