1. Always anticipate Phase II.
As you work to satisfy the 80% in Phase I, remember that excellence requires design for diverse stakeholders. Anticipate and keep a vision of a definite Phase II as a way to return to unfulfilled opportunities. Spend some time to discuss and record those good ideas, don't ignore them even if it is too early to work on them.

2. Cultivate Top-to-bottom empowerment.
When excellence is your standard, Quality and Innovation really are everyone's responsibility. Anticipate that good ideas will be coming from all levels; be ready for them and cultivate them. Praise is the best fertilizer, and the best praise is to see a suggestion taken seriously and implemented. Do that and you will find that good ideas will multiply.

3. "Two-fers": Get more benefits for the same (or nearly the same) cost.
Nothing good is free, but anticipating secondary benefits is very close to getting something for free. This isn't automatic. It might require a little extra expense as well as coordination across different executive groups in your company, but it will definitely make a huge difference in long term success.

For example, are there existing systems that just need a slight adaptation or coordination to provide new benefits to other customers and areas of the company? Can you group related additional changes and follow the same planning and testing? Did you follow a process that gets quality certification without doing the extra 20% that takes real costs off the bottom line?

Good analysts and software developers will see your ideas and systems in ways that help minimize costs and maximize benefits, including secondary benefits and accelerate your business.
