You and your staff have to be able to answer the 5 W's for just about every aspect of your business — whether to each other or to your customer. "How" is almost always irrelevant and only matters if your role in the business is to maximize efficiency and/or meet a production target, financial or otherwise.
Your customers will assume you know how to do what you do. It's why they hired you in the first place. However, customers can almost never assume the 5 W's as they are the DNA of your business process as opposed to your end product. That's why great customer service is all about constantly communicating the 5 W's of your work for your clients. All the value (i.e., money) is in the 5 W's.
To run your business effectively, your primary (if not biggest) concern has to be that things are getting done. If your staff can answer the 5 W's for their area of responsibility, you will know the answer and be able to act if things aren't happening the way you want them to. How doesn't answer the question. So long as you are comfortable that your staff are good actors with integrity, not knowing the ins and outs of how they are doing what they are doing is okay. And, if they are not good actors, why are they part of your staff?
How your art comes to be, how it feels to you and your client, how you seek to define what you have done, etc. is key to your creative process. Leave "how" there and let answering the 5 W's rule your business.
