Scientific, Systematic Succession Planning

I would like to understand how the BEST test in the world mentioned in this article (5 dimensions) relates to strengthsfinder principles (4 domains).
Was DRIVE added?
Why another typology? Gallups full portfolio should remain transparant.

Luuk, here's an answer to your question above.

The five dimensions including drive are derived from Gallup’s Executive Leadership Interview (ELI), an in-depth leadership assessment, which is a different assessment than StrengthsFinder. ELI is making a prediction of executive level leadership performance. StrengthsFinder and the 4 Domains of Leadership is aimed at helping teams and individuals at all levels or an organization, to think about the balance of their leadership strengths. StrengthsFinder does not make a prediction of future leadership performance. With two different assessments designed for completely different purposes it is not surprising that the research dimensions and domains are different.

Please educate me on the ELI.
How culture-free are the executive leadership performance predictors?Does ELI factor in differences brought about by nature of business,existing challenges at executive's entry, on-boarding/transition management process,etc? What do current research data say about their ability to actually predict successful executive performance.

Joven, here is an answer to your question above. The ELI is an in-depth, structured interview comprising questions with researched, psychometric properties that in combination provide a prediction of future leadership performance. Initial research and subsequent validation studies have been conducted cross-culturally within client organizations revealing minimal cultural bias. The ELI provides effective insights into how leaders will adapt to and perform in different business scenarios. We do not change the assessment dependent on these scenarios, or to reflect them, because doing so would remove the predictive ability of the tool - these are factors that highly skilled analysts with a deep knowledge of a business are qualified to navigate. Research has shown the ELI to be a remarkably strong predictor of leadership performance both in client based and broader meta-analytical studies. If this is an area of greater interest then please contact your nearest Gallup Office (http://www.gallup.com/corporate/1276/Global-Offices.aspx) and they will be happy to provide more detailed information.
