RDM In Module Reflective Writing– the role of data

What- when making a decision, data are very important. A good source of data could give management team a good result. And of course wrong data collected could lead to very unfavourable outcomes. For example, when using cost-benefit analysis, the financial figured used for the calculation must be corrected since the whole cost-benefit analysis relies heavily on data. Why- the role of data is important. But the problem is how to ensure that the data are collected correctly? There are two ways of ensuring the data are valid. First of all, it may be useful to double check the data again after they collect. Secondly, data collection can use different sources to validate the trueness of data. How- in the past I was focus too much on how to use decision tool, and ignore the possibility that the data may not be correct. From now on, I will question the sources of data and whether they are indeed correct or now. But the ways to validate are still to be explored and study.
