QMy company has a "make or break" project that I've been assigned to lead. The problem is that there are two factions with strong interests in this project and they don't agree on the direction we should take. How can I get them to come together?
ATry a carrot and stick approach. What's in it for them if they compromise? What'll it cost them if they don't?
The inner game
Success will depend on keeping the collective benefit from this project front and center despite pressure from both sides, and will require great effort on your part. Start by listing your strengths, including tangibles such as organizational, communication, and negotiating skills, and intangibles such as resilience and determination. Other people who can provide knowledge and support, and who may have leverage over people in the two factions are also assets.
Then create a roadmap of successes, starting with your ultimate project goal. How will this project benefit your company as a whole? This will give you the "greater good" perspective that you'll need. Then look specifically at the ways that subgroups within the company will be affected to help you build a case that will support forward movement for both parties. Working backward, establish a set of intermediate successes that will help you bring the parties together toward the collective goal.
Develop an equally clear statement of the risks of failure, including multiple perspectives -- the whole organization, departments within the organization, and the individual employees.
Finally, list as many "derailers" as you can think of, their likelihood, and ways around them. Involve some of your allies to help develop as complete a view as possible.
