Leadership Impact (L/I)
Build More Impactful Leadership with the LSI Impact Assessment ™
The Leadership/Impact® (L/I) provides managers and executives with unique insights into their personal leadership strategies – and the impact of those strategies on others’ behaviour and performance. The product of extensive leadership effectiveness research, it’s used by organizations worldwide and has been featured in leading peer-reviewed academic journals.
The Leadership/Impact® (L/I) assessment from Human Synergistics is a world-class 360° feedback tool designed specifically for senior leaders and executives. Unlike many assessments that focus only on what leaders do, L/I goes further by measuring how their strategies are experienced by others and the impact those strategies have on culture and performance. Leaders receive confidential feedback comparing their intentions with how colleagues, direct reports, and other stakeholders actually experience their leadership, providing powerful insight into the alignment—or misalignment—between strategy and impact.
By examining both leadership strategies (how leaders influence others) and impact styles (the behaviours and outcomes leaders encourage), L/I helps executives understand not only how they are leading, but also how they are shaping the culture around them. It highlights whether leaders are fostering Constructive behaviours that drive engagement, collaboration, and innovation—or unintentionally reinforcing defensive norms that limit effectiveness.
With clear, evidence-based insights, the L/I becomes a catalyst for targeted development, coaching, and culture transformation. It equips leaders to refine strategies, enhance trust, and align leadership behaviour with organizational vision. Ultimately, L/I empowers leaders to create the conditions for sustainable success—where people and performance thrive together.
How it works
L/I gathers feedback on each leader via two mechanisms:
- The L/I Self-Report Inventory: The leader describes their own perceptions of their leadership approach and how they’d like to shape and influence others’ behaviour.
- The L/I Description-by-Others Inventory: Up to 12 of the leader’s peers, managers and/or subordinates (chosen by the leader) provide feedback on their leadership approach, impact and overall effectiveness.
Each inventory meets rigorous academic and psychometric standards and takes 20-30 minutes to complete. Both are available online and on almost any digital device, as well as in paper.
The inventory data is processed electronically, and a confidential report is provided for the leader that: identifies the gaps between the way they’re perceived and the leader who they want (and need) to be considers the implications for their colleagues and their organizations, as well as their personal and professional performance makes recommendations for change. A Peak Experiences accredited practitioner then guides the leader through the findings and helps them to develop strategies and techniques to improve their long-term effectiveness and impact.

“Frank Gallant uses the line "How you think, determines how you behave..... and how you behave defines your culture.” He clearly defines the building blocks of constructive leaders through an unbiased assessment process, clearly lays out the expectations of being achievement based, self-actualized, humanistic - encouraging and affiliative. He listens to your experiences, provides an understanding of how or when you may be struggling, gives you the tools for change and then sets the expectation for you to do the work to be that constructive leader - one that has the desired impact they are looking for.
In my opinion, Frank Gallant is the epitome of a constructive leader!”
