I've been asked to produce a report on the effect of vendor delays on my timeline.

I have a team of 6 engineers who are supposed to be a PC roll out team. The Vendor is delayed because of various applications other parts haven't been tested in the new environment. Which is leaving the rollout team idle for x amount of days. This is a given but how do I record this time and the knock on effect on the timeline.

On paper the engineers should be knocking out 150 to 160 laptops per week. They work 8 hour days, so one per hour. We are rolling out 1700 pieces. How can I report this in excel, with the time constantly being impacted because of various applications and or infrastructure sometimes not being in place?


An easy solution would be to load the values in excel of your planned work, and then load the values of your actuals, and you can display progress using a cumulative graph. Here's an example: enter image description here

I used 155 as your planning value and loaded it assuming equal numbers each week, which produced a flat loaded schedule. Then I made up actual values but showed it to be behind the plan. From here, you can forecast where you are headed based on actual performance using a simple forecast formula in excel, or you could bring a bit more sophistication by using Earned Schedule analytics and it will predict when you will finish based on your schedule performance to date.

The graphic is a nice way to show to stakeholders--easy to read and digest and hard to dispute in terms of your forecast from it.

Adding two types of forecasts: formula in excel and ES:

    You could add a 3rd column of the adjusted forecast, if you want. – Danny Schoemann Dec 4 '18 at 13:19
