The substance in product management (PM) is the hard skills needed to learn and excel at building great products (i.e. customer discovery). Style is the soft skills needed to get things done (i.e. influence without authority). Most product managers tend to undermine the importance of style. How can managers learn to improve?
Most of the soft skills associated with PM involve making a compelling argument to the stakeholders. How?
Present a particular perspective to steer the audience to the desired conclusion.
Leverage the shared opinion of others to convince key stakeholders.
Redefine your initiative in terms of a decision maker's own goals.
Make another believe the idea was their own.
Summarize first-party research succinctly. Surfacing too much data will dilute the argument.
Recast your argument as an engaging story.
