how to do a good go-to-market strategy for my company ?
If your company doesn't currently have a Go-to-market strategy, the first thing I would do is go to each department head individually and ask, "If we were to launch a new feature or product, what would you need to do in your department to support it, and what would you need for you to accomplish these tasks?" This will give you a list of items that are vital to the business.
Then, organize what you found and assign an owner to each task so that you know who to contact.
You'll also want to work very closely with the product team so that you know the feature or product very well. You'll want to understand:
Who it's for?
What problem does it solve?
What are the old ways of doing things?
What is the solution?
How does it provide value?
Are any competitors doing it?
Next, work closely with marketing to create a standard bill of materials for each launch tier:
Tier 1—big and noteworthy feature
Tier 2—match the market feature and win new customers /new and innovative but keep existing customers.
Tier 3—match the market feature/keep existing customers). The bill of marketing materials should be a baseline for each tier, and you can add or remove different assets as needed.
Finally, communicate early and often with different groups and departments. Set up weekly syncs to ensure progress toward the launch deadline and that any roadblocks are addressed.
