HSI is a natural part of the systems engineering process. It adds minimal up-front cost for significant benefits and cost savings. Optimizing the system for performance and lifecycle cost benefits the customer. Ensuring early consideration of HSI factors reduces the risk of costly rework to the contractor. Delivering a system which is mission effective with reasonable lifecycle costs benefits everyone.
DoD acquisition policy requires Human Systems Integration (HSI). Various human-centered engineering approaches are also gaining traction outside of military projects. But is HSI just a fancier way of saying Human Factors Engineering (HFE)?
Human systems integration (HSI) is a systems engineering function with the goal of optimizing system performance and cost across the entire system lifecycle. It ensures that the human elements of the system are given at least as much consideration as any other component across the entire project. HSI is a relatively new and often misunderstood term. Here are the basics.
The university writing center is an undervalued resource. Most students, especially those in technical fields, don’t bother to use it because they get decent grades on their own. Don’t make the same mistake as your fellow students! Using a coach can save you time and stress while improving your writing skills. It’s free!
When proofing a document with the word “materiel”, you will look like an idiot if you replace every instance with “material”. Find out exactly what it means and how it affects systems engineering practice.
You can’t buy an anti-aircraft gun, a nuclear submarine, or a spy satellite from a catalog. The DoD acquisition process affects systems engineering practice in every industry and academia.
