The success of the people tech solution will depend on how well you are able to optimize on these four fronts:

Optimise for process efficiency -

How well is the tech solution able to efficiently execute the business process which was running in the previous state? Say you were running on excel sheets before this, is outputs of tech should be far more than the outputs that excel was delivering for you.

Optimise for time (taken to completion / saved) -

How much time is being saved by the process owners and executors to complete the task? Any time saved to achieve the same result is a win. However, the ultimate goal should be, to produce x-times results by reducing x-times time taken.

Optimise for business outcomes

How efficiently are the ultimate business outcomes being achieved through the tool. This sums the above two outcomes and is pointed to the ultimate goal that business was trying to deliver.

Optimise for tangible data outputs

The output of tech → is input for people analytics. You must ensure that the tech processes that have been designed, must produce data that in turn, will feed into the people analytics. Do not sacrifice 1 & 2 and cut corners by not delivering enough data.
