Ongoing research has formed the foundation for the development of some of the most widely used models worldwide, which are applied in SHL’s methodologies such as:
- Universal Competency Framework (UCF)
- Contextual Business Challenges
- Enterprise Leadership Model
- High Potential Model
- Sales Transformation Model
One of the most widely used and scientifically backed competency frameworks globally. Validity studies confirm a high correlation (0.86) between 125 occupational profiles from the O*NET database and the corresponding profiles created using the UCF. The UCF serves as a reliable foundation for designing assessment and development programs with high predictive validity.
Based on award-winning research (SIOP 2018), the model covers 27 critical professional challenges that any leader in any organization must navigate. Integrated into the SHL Insights platform, it provides real-time data on each leader's selected challenges, boosting the validity of internal talent decisions up to 4x, for example, in succession planning and talent mobility programs.
Developed through extensive research involving 4,000+ employees and nearly 200 HR Directors from 300+ organizations worldwide. The model captures the modern leadership competencies linked to increased organizational performance and sustainable growth, with strong impact in areas such as innovation, customer satisfaction, organizational commitment, and revenue growth.
The result of multi-year research by SHL and Gartner, the HIPO model focuses on the three key factors that together predict successful long-term advancement (up to the most senior levels): Ambition – Ability – Commitment. Specialized tools are provided to assess the relevant potential within an organization's existing talent pool.
SHL's research across 14,000+ B2B sales professionals identified 3 mega-trends and shaped the SHL Sales Transformation model, which focuses on the key competencies for success in relevant roles and delivers: 3x the likelihood of achieving sales targets, 2x revenue through sales, and a 33% increase in the probability of exceeding sales targets.
