tRial anD eRRoR e second important point is that controls "construction" is not like building infrastructure construction. Programming controls requires interpreting the opera- tional sequences and then applying trial and error to ensure the intent is met. As the terminology "trial and er- ror" implies, this is not a serial effort and certainly not best performed in solitude. Evaluating the interdependencies and consequences of programmed cause-and- effect scenarios are efforts that both your engineer and commissioning agent should participate in early and oen. All too oen controls programming fails to properly interpret the engineer's sequence. Other times, the interpretation is correct but the programming creates other undesirable system issues. While the controls integrator should be empowered in these early stages, charge your commissioning agent with ensuring the design and operational intent is being met. is is the phase where conversa- tions about the philosophy can strengthen understanding and proactively head off potential issues. e facility's future operators may weigh in at this juncture but at the very least the commissioning agent should understand the operations team's require- ments and ensure adherence. Proper system configuration will help improve operability. Ideally the controls system is config- ured in a simulation environment to mimic the ultimate installation. When provided by the controls integrator, the majority of issues can be resolved and optimization achieved ahead of the end of project push. If this is not an option on your proj- ect, provision the time and resources to go through the test / fail / re-program / re-test cycle multiple times. It is critical through this process to maintain strong revision tracking and change control. e risk otherwise is that changes affect elements that have been tested and new issues arise without detection. is happens when testing is rushed and changes are made without good control. A system seemingly validated is instead harboring hidden failure points. stRess the systeM In most mission critical installa- tions, the integration period is your best opportunity to really stress the system and identify the weak points.
