PowerProv scores nearly double the industry training benchmark.
A single half-day PowerProv workshop improved every skill measured.
- 96% of participants rated higher - zero declined
- Nearly 2× the average industry team training impact
- 4.73 / 5 rating - across 26 participants
- A single half-day PowerProv workshop improved all 15 skills measured.
- 96% of participants improved, and the group rated the session 4.73 out of 5 stars.
- The overall effect size was 1.13, nearly double the average for corporate training.
- Group presentation skills jumped 25%, the biggest single improvement.
- Active listening, a skill Smokeball specifically asked PowerProv to focus on, rose 16%.
The problem
Smokeball makes legal practice management software, and much of its team spends the day in conversations with prospects and clients. Going in, they leaned on scripts and set methodologies, trying to recall the right move at each stage of a conversation instead of responding naturally in the moment. That worked for the polished top performers, but left others inconsistent, and few were quick on their feet when a call went off-script or a prospect pushed back.
What PowerProv did
A half-day workshop, designed to help them with presenting as a group, thinking on their feet, and leading under pressure. No trust falls, no comedy, no cringe.
In addition to improving overall communication, collaboration & confidence, Smokeball especially wanted their team to become stronger, more active listeners.
Every participant scored on 15 skills before and after the workshop - data that also feeds PowerProv's Personal Power Index™, the ongoing study tracking provable outcomes across hundreds of participants.
“Definitely do it. PowerProv is an absolute game-changer.”
The result
Every one of the 15 skills we measured moved up, and none went backwards. Group presentation skills rose +25%, leadership +20%, and thinking on your feet +18%: the skills tied to how people show up and contribute in a team, not just individual capability. Active listening, the skill Smokeball most wanted to build, rose +16%.
Almost immediately, the change carried into the day-to-day. People were using what they'd practised in real client conversations, holding steady through objections and pushback instead of stalling, and putting new tactics to work without being asked.

- PowerProv training has nearly 2× the impact of typical corporate training programs. One half-day session moved the needle far beyond industry norms and earned a 4.73 / 5 star rating.
What "nearly double the benchmark" means
We measure the size of the shift with a standard called effect size: one number that captures how big a change was, not just whether it happened. The published benchmark: a peer-reviewed meta-analysis of workplace training found an average effect size of about 0.62. Smokeball's workshop came in at 1.13, nearly double that industry average, and past the 0.8 mark researchers call a "large effect."
A paired t-test returned p < 0.0001, less than a 1-in-10,000 chance the pattern happened by chance. And this wasn't one enthusiastic voice: 26 people rated the session, averaging 4.73 out of 5, with 77% handing out a perfect score.
