I'm curious as to what others use for a clear concise definition for a bad actor. Knowing that there can be many factors that contribute to that definition.

Bad actor concise definition should vary from organization to organization depending on its' Asset performance management maturity level ranging from reactive to emerging to proactive. Generally speaking, Bad actors are those which impacts business goals (Health, safety, environment & Financial) and/or those which fails too often. Right approach would be to enlist all equipment from historical events which resulted in shutdowns, breakdowns, slowdowns, quality losses, LTIs/MTIs, Regulatory fines etc..and rank them based on 3X3 or 5X5 risk matrix (Consequence severity category Vs Frequency/Probability/likelihood of occurrence). Secondly list down Top 10 high maintenance cost work orders (Equipment's) and high repeat failures equipment and rank them too based on risk matrix. Finally prepare a consolidated bad list based on allotted Risk & prioritize them for emergent, urgent or planned resolution or elimination.

In our company, the bad actor list is selected by a consensus of the plants' reliability management team.  We revisit the Top 10 list quarterly.  The selection is based on criteria such as production loss costs, maintenance costs, urgent work orders, quality costs, asset criticality rating, total no. of work orders, and safety incidences.  Weightings are put on the categories to give a total number of highest on the bad actor list to lowest.  However, the final selection is always left to the team, as there can be qualitative information also such as new asset, or food grade asset, or safety asset, etc.  The selection of a Top 10 indicates that we should assign resources to specifically address those assets beginning with no. 1.  I agree with the comment on selection being an organizational focus and impacting the facilities business.

​Bad Actor Definitions could vary from Organization to Organization and also with the Functions that are responsible for the Asset.

In Maintenance I've seen the simple Definition of Bad Actors by Failure Count and by Maintenance Cost (some Equipment would fall in both the Lists). The Focus is on the Assets with Chronic Failures and that which Cost a lot for Maintaining them.

Hi all,
​It's not just about looking for the equipment or assets that have a high incidence of down time or cost, or cause system outage to call the bad actors. You need to dig a little deeper and look for themes such as instrumentation or lubrication etc which may be common across many systems but individually don't have too greater impact. Collectively these may be creating greater lost up-time or cost than individual equipment losses.

Additionally its worth looking to see if there are any major (and probably one off) events which are dominating as these will skew the results and prevent other things from having a proportional high impact on the metric – could be down time, cost etc etc.
Another interesting point is that if you present the bad actor exactly as per the system data you may find it concur with the shop floor which suggests miss-reporting and data inaccuracy so it's always a good idea to validate before publishing. You may have to do some data cleansing.
