How do you build a scalable launch process? What are the failure modes or signs of an unscalable launch process? How do you determine when (or if ever) a product launch should be delayed to match the product marketing launch schedule?

Simple answer here is a great Tiered model, a NPI process (for larger companies), and differentiating between Launches and Releases. Often see many product launches that are really more release marketing versus integrated product launches. 

You have the greatest outbound marketing launch in the world, but ultimately all the launch and growth levers in the world won’t make new products successful in market without 4 things…

• Top-Down Accountability: Executives setting and aligning around targets, and holding each other and stakeholders accountable.
• Field/Business Incentives: Who is going to profit from putting the effort into this new product? Iconic incentives (SPIFFs), Quota Accelerators
• Specialized Expertise: Especially in SC org and CS expansion, and when sales-led. SC Experts (SME program, Evangelists, PMMs.
• Inspiration: Product vision, internal win stories, bottoms-up momentum from field, inbound demand.
• Strong NPI: Operational rigor bring products to market

A few things need to fall into a consistence cadence to accomplish scalable launch processes:

• Timely visibility into the product roadmap

• GTM team alignment on accomplishing sales enablement ahead of marketing launch dates

• Marketing team education and buy in on what's being launched resulting in a channel/swimlane plan

If one of these is weak, it tends to impact the rest of it. Also, creating awareness within the company that "code complete does not equal to marketing launch date" -- this is a concept that gets a lot of push back. This is a discussion that needs to be had upfront while preparing for a launch as marketing has the best picture on the ideal launch timeframe.
