What inspired this Wish List Request?
This request is aimed at rare event control charts (G and T). In Control Chart builder, these charts are easily created from the drop-down menu that changes Shewart Variables to Rare Event. When the control chart changes to a G chart, however, the Phase dropzone disappears.
Please describe the new or improved feature or solution you would like to see.
This request is to simply keep the Phase dropzone for both G and T charts. An inquiry into Tech Support suggested this is not a bug, but the Phase dropzone was not added to the rare event charts.
What would the value be to you and/or other users if this new feature is provided?
This type of control chart is routinely used in hospital settings where adverse events are tracked (infections, needle pricks, patient falls, etc.). Typically training or protocol changes are administered when the frequency of adverse events are unacceptable. A Phase dropzone will simplify comparisons between the times before and after corrective actions are put in place.
Is this an external customer request?
This was discovered during demos with a prospective customer UC Health and was a requirement for their use case.
Is there a competitive software package that has this feature or solution that we should be aware of?
Minitab, Advantive PQ Systems
Will this impact a renewal, expansion, or adoption at a customer, and does this put an account at risk if we do not address this?
This will standardize the platform so there is consistent dropzones/workflow for all the supported Control Charts
Thank you for submitting this request.
From Development: "Currently, both Rare Event charts use all the data to form estimates from either the Weibull or the Negative Binomial distribution in order to form the limits, regardless of the presence of subgroups. Adding a phase would involve a non-trivial restructuring of the data as the calls to the estimation routines don’t handle the Trellis-style data format."
Given the current priorities and backlog in JMP 19 am moving this to not planned for now, but will leave it open for future consideration.
