What are you really looking for in the change?
Careful before you answer. I bet I can sum up your answers in one of two categories: Comfort or Security.
If it's comfort you seek, your actions will typically include arguing against the facts, diminishing the value of the insights or wisdom of others and making the case that things aren't that bad. You might even highlight how other organizations have made similar changes and failed.
If you are seeking security, you will seek out data and analyze it, listen closely to the perspectives of others and evaluate possible future scenarios if change is undertaken-or not. Time will also be spent looking at how other organizations succeeded or failed with similar changes, and taking note of their strengths and weaknesses.
One approach is fighting to keep the status quo. The other one is fighting to be relevant in the future. Which is more important to you... being comfortable or being secure?
