Build or Buy HMI: How Do You Choose? QSI Whitepaper leads you through this tough decision. As you design your next complex machine, the operator interface, or HMI (Human-Machine Interface), can either make the project a success or a failure. The vital question is should you develop it in-house or outsource it? The operator interface ultimately determines the usability of the machine. For all the hard work, engineering dollars and other valuable resources you invest in the development, the HMI can literally make or break the success of the product release. A good interface is invisible, simply because it works. Usability and functionality of the interface determines the user’s perception of the machine itself and often times the reputation of the manufacturer also. On the flip side, a bad operator interface can be detrimental to the potential of what your machine offers your customers. Given how critical the interface is, it’s vital to ask yourself if it is best to design and build the HMI yourself, or outsource the development. This question is easy when you approach it correctly and consider the full scope of issues from both perspectives. A whitepaper from QSI sorts through the details on both sides, while keeping sight of the big picture:
These are only a few of the issues discussed in QSI Corporation's whitepaper, "Rugged Operator Interface Terminals: Build versus Buy." Download this discussion, complete with pros and cons of each approach. Click www.qsicorp.com/support/whitepaper/ to get your copy. |
