Successful systems are created by engineers who understand and design to the ultimate objectives of the project. When we lose sight of those objectives we start making design decisions based on the wrong criteria and thus create sub-optimal designs. Scope creep, group think, and simple convenience are frequent causes of this type of variation. An effective design assessment tool is a touchstone by which we can evaluate the effectiveness of ongoing design decisions and keep the focus on the optimal solution.

Agile promises to deliver capabilities to the end user faster and more effectively. Government project offices can realize the benefits, but must carefully design their contracts to support the agile approach. A growing body of expertise, lessons learned, and acquisition resources are available to help make it happen.

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.

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.

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.
