Research and development by Robert A. Cooke, Ph.D.

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, this 360° feedback assessment for leaders is used by organisations worldwide and is featured in Center for Creative Leadership’s book, Feedback to Managers.

How it works

L/I gathers feedback on each leader via two mechanisms:

  • The L/I Self-Report Inventory: The leader describes his/her own perceptions of his/her leadership approach and how he/she would 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 his/her leadership approach, impact, and overall effectiveness.

Each inventory meets rigorous academic and psychometric standards and takes 20 to 30 minutes to complete. 

The inventory data is processed electronically, and a confidential report is provided for the leader that:

  • identifies the gaps between the way he/she is perceived and the leader who he/she wants (and needs) to be.
  • considers the implications for his/her colleagues and their organisation, as well as his/her personal and professional performance.
  • makes recommendations for change.

An accredited Practitioner then guides the leader through the findings and helps him/her to develop strategies and techniques to improve his/her long-term effectiveness and impact.

The L/I surveys are available online on almost any digital device as well as in hard copy format.

Complementary tools

We recommend that you apply L/I in tandem with the Group Styles Inventory™ and Organisational Culture Inventory®. Together, they enable an integrated approach to developing individual-, group-, and organisational-level thinking and behavioural styles.

You can also use L/I alongside Management/Impact® as an integrated approach to developing your mid- to lower-level managers.

The benefits for your organisation

L/I provides valuable insights into your leaders’ influence and effectiveness, and helps them to confront and overcome their personal barriers to achieve outstanding performance — and ultimately the performance of their teams and your organisation as a whole. It’s particularly useful for:

  • initiating and promoting leadership development
  • coaching individual managers and executives
  • evaluating your leadership development initiatives
  • promoting a healthy organisational culture
  • enhancing organisational effectiveness

Make L/I part of your drive for change

L/I is best applied by people who’ve been trained to use it. We offer two options:

  • One of our network of accredited and experienced consultants can help you use L/I and develop truly effective and influential leaders. Simply contact us to find a consultant who’s right for you.
  • You can 'do it yourself' by arranging L/I accreditation for one or more of your team members. This will ensure they have the skills to administer the L/I and implement meaningful leadership-development strategies. To get started, contact us to register for the accreditation workshop.
