How to build better models: Applying agile techniques to simulation

For simulation practitioners, the common steps in a simulation modeling engagement are likely familiar: problem assessment, requirements specification, model building, verification, validation, and delivery of results. And for industrial engineers, it's a well-known adage that paying careful attention to process can help achieve better results. In this paper, we'll apply this philosophy to the process of model building as well. We'll consider model building within the framework of a software development exercise, and discuss how best practices from the broader software community can be applied for process improvement. In particular, we'll focus on the “milestones approach” to simulation development - based on the popular “agile software” philosophy and our own experiences in real-world simulation consulting practice. We'll discuss how thinking agile can help minimize risk within the model-building process, and help create a better simulation for your customers.
