There are three different trend types and the closer the gap between the
confidence lines the more confidence you can have in the result. Setting thresholds also assists in gaining
visibility into the trend impact.
Normal Trend
Normal Trend
Step Trend
This takes in to account a change in the business, which you are aware
will be happening.
Including
the step will allow you to see how much impact that change is going to have on
the overall trend.
In
this scenario it has little or no effect.
Average vs.
Peak Trend
I am often asked the question do I need to look at the averages or do I
look at the peaks? You can produce a chart like the one below which looks at
both.
The red line in this example is the peak trend and the green line the
average trend, this tells me that the peak trend moving forward is not as significant as the average trend.
So when I start analyzing this environment I’ll choose to look at the
averages rather than the peaks.
On Friday I'll take a look at Forecasting and Virtualization and summarize the series for you. In the meantime join our Community and get access to our on-demand webinars, papers and performance tips http://www.metron-athene.com/_resources/index.html
