I am trying to implement Maximo health at a site. The data they have will not support using the OOB formulas. My goal is to create a simpler scoring system. As an example, they do not have installation date on the vast majority of assets. Can I replace those with simpler versions of MTBF, MTTR, etc. ...? Can the formulas omit the installation date.? Have not been able to get that to work.
