Subjective Conclusions

Poor project controls make it difficult to get accurate measures of time spent in each activity.

Communication with the provider in the earliest stages to agree on implementation strategy simplifies the entire task and especially the integration time.

It is not always reasonable to ask a vendor to implement in EPICS - the time to come up to speed should not exceed the time saved.

Do not put too much in a PLC - they are difficult to maintain for complex logic.

Require integration as part of the result from the supplier.

Even when selecting common hardware - coordinate the schedule for implementing the driver to avoid duplication of effort (and code to maintain)
