Changing and improving your technical processes is a complex endeavor.
You know your process needs improvement.
You know there are better options out there.
You could be saving time and money.
You could be doing things more effectively.
But you are looking at it from the inside. It can be overwhelming to analyze internal processes, much less attempt to prescribe solutions with limited industry exposure and research bandwidth.
You still have a job to do, a department to keep up and running while the options are evaluated and a new plan is formulated. You are an expert in where you are; you need an expert in where you could go.
You need someone with industry experience and an outside perspective to ask the right questions, expose your blindspots, and offer solutions.
