Graphical data representations (line plots, bar charts, pie charts, surface plots, etc.) provide valuable insight and an efficient method for evaluating process performance. We help companies understand how to make the most of their data acquisition and control systems to effectively use data graphing for process acceptance.

Many modern control systems can be programmed to continuously evaluate process data in real time for conformance with process tolerances. Process acceptance can be simplified to quality review of a process data chart combined with identification of out-of-tolerance incidences reported by the control system (e.g. alarm or process deviation log). This type of streamlined operation results in high confidence in process performance and repeatability.

Process monitoring and acceptance in this manner also leads to greater uniformity for batch processes. In addition, better control can be achieved by implementing predictive maintenance and process changes based on the historical trends identified from process deviation logs. Trends in process deviation logs may be evaluated from graphical representations indicating the interrelationships among different types of deviations and the frequency of deviation repetition.

Presentations and submittals to upper management, prospective customers, investors, and regulatory agencies can be greatly simplified by using graphical data representations and schematics. We assist our clients with the development of as-built schematics that depict facility layouts, utility and equipment design, workflow, space utilization, manufacturing process performance, and many other topics of interest. These graphical preparations often supplement our other support services such as validations, SOP development and project management.
