Product Management Checklist

Scrolling fast through my Google Reader on the 'How to be a Good Product Manager' Blog. Only reading the post titles. Smiling. There's some good advice here.

• Define the problem before solving it
• Decide go / no-go before buy vs. build
• Differentiate to avoid being a “me too”
• Reinforce your product-related communication
• Reconsider your Jack of All Trades strategy
• Consider all details of add-on features
• Lack of complaints does not equal success
• Adapt your product management practice
• Technology is not better if it does not add value
• Choose your strategic alliances carefully
• Take a cautious approach to problem-solving
• Measure the impact of product changes
• Deliver customer value, not product features
• Stop gathering requirements
• Delegate tactical responsibilities
• Be comfortable being uncomfortable
• Plan for the present and likely future
• Work effectively with sales

How many of these could be applied to upgrading your marketing/PM approach?
