Research & sources

What research says about role transition, listening, feedback, delegation and hybrid leadership, with original sources and limits.

These studies are selected from the SAY IT EARLY reference list. They inform parts of the guide. The EARLY METHOD™ and its practical tools have not been independently tested as standalone interventions.

CCL 2014 / 2026 · report and analysis

Why is the first leadership role demanding?

In a CCL sample of 295 first-time managers, people management and authority were frequently mentioned challenges. A later analysis of more than 48,000 leaders across levels also reports people and time pressures.

This is why the guide begins with the role transition and actual conversations. Neither sample predicts what every new manager will experience.

Why listen before deciding?

The review connects workplace listening with relationships, trust and other desirable outcomes. Listening can reveal information that changes a leader’s next step.

In the EARLY METHOD™, Ask follows Evidence. The review does not validate this five-step sequence or any particular script.

Kluger & DeNisi 1996 · meta-analysis

Does feedback always help?

Feedback interventions improved performance on average in the analysis, yet more than one-third of the recorded effects decreased it.

The guide uses specific observations, a real question and a checkable next step instead of vague judgements. The study did not test the guide.

What does hybrid-work research show?

At one technology company, two work-from-home days per week reduced attrition without a detected performance penalty.

The guide favours clear outputs and documented decisions over reading presence signals. One company and one arrangement do not set a universal policy.

Sources in the book were checked on 19 September 2026. This is a targeted selection, not an exhaustive systematic review. Each finding has its own research context.
