QuesTek services engagements are typically structured as a sequence of deliverables, based on client needs. Many clients start with analysis of their materials challenges, then add on additional analysis and data. To advance the solution further, clients then engage for modelling, which includes analysis and data. The ultimate engagement step is a full novel design, which includes deliverables from the three preceding steps. All these service levels can be available within a retainer structure, which provides favorable pricing and response times to address ongoing client materials challenges.
