Continuous improvement is the key to successful pork production, and various top companies have ways in which to do so. Clear expectations can be communicated through protocols, and then can be evaluated. Evaluations are best done by pass/fail, yes/no type systems. Communication between farm staff and management can help identify areas of the protocols that need to be amended. By encouraging change and not over-analyzing things continuous improvement can occur. When expectations are not met they are discussed, and the reason behind missing it identified and future ways to avoid it decided.  Finally, expectations are prioritized and done without rushing. Clear expectations, objective measurements, communication, and effect changes are ways top companies can continuously improve.
