We knew we had to get the job done over the four-day holiday weekend. That’s all the time the customer had to give us to replace hardware, do new IO and complete the process checkouts and establish production support. Not only that, we were installing an upgrade complex legacy PLC program that no one was familiar with. So what did we do? We set up an around-the-clock schedule, learned what was necessary, and completed the project in 3 days. The customer was delighted, and their people got to enjoy the balance of the holiday with their families.
