VISTECH addressed this challenge by setting up a development environment at its office in Hartford, CT. After acquiring the code, VISTECH collected requirements from the aerospace company and its PLC vendor. By controlling the project using STEPSTM, VISTECH delivered a phased, fixed price project.
STEPSTM stands for Stages, Tools, Evaluations, People, and Strategies. It is a project methodology designed by VISTECH to track and manage projects of all sizes in order to provide a reliable approach for the development of robust applications, while ensuring exceptional quality, continuity, consistency, and control through all stages of a project.
For this project, Evaluation was a key component. It allowed project stakeholders to monitor and adjust project tasks as necessary, while adhering to project requirements. VISTECH periodically delivered code updates to the aerospace company’s staff who unit tested and confirmed development direction. By receiving required approval before proceeding, VISTECH ensured engagement with the client, ability to accelerate deliverables, and mitigation of complex communication risks.
Software enhancements to integrate the new PLC were completed on time and within budget. Onsite testing followed and included executing both manual and automatic quality assurance procedures. During testing, the software communicated with nozzles to deliver air at various pressures and gauges to record temperature and pressure readings at varied time intervals. Testing concluded within three months from project start, exceeding expectations.
