Case Study

A leadership team, reconnected.

Major Australian Retailer

Connected Leaders Program

The Challenge

A Major Australian Retailer had run leadership training before. What they wanted this time was different: a development experience that would fundamentally reshape how their people lead, innovate and build high-performance cultures. Their emerging leaders were operating in silos, capable individually but disconnected across functions. The business needed an aspirational pathway that would embed new frameworks and peer support systems, and lift capability across successive cohorts rather than in one-off bursts.

The Approach

We built an annual program around the Connected Leaders System. Immersive Learning Labs delivered content customised to each leadership group. Targeted Coaching Clinics provided personalised one-to-one support alongside structured peer accountability. Cross-functional cohort experiences deliberately grouped leaders who wouldn't otherwise work together. Between sessions, Mind Bite videos, individual learning journeys and regular reflection kept the thinking alive at exactly the point where most programs lose people.

The Outcome

Four years and multiple cohorts on, the program has produced measurable capability lift across every cohort, mentoring relationships and peer support networks that have outlasted the program itself, and stronger cross-functional collaboration. It has become the development pathway leaders across the business ask to join.

AGL

Culture Change & Leadership Program

The Challenge

A pending de-merger required AGL to bring a 1,400-person contact centre together with a 300-person customer operations team — two functions with separate identities, ways of working and expectations, now expected to operate as one. It called for more than a restructure: a re-alignment on purpose, a clear-eyed view of the culture they had against the one they needed, and leaders capable of taking 1,700 people through significant change toward a more customer-focused, innovative approach.

The Approach

We designed a multi-year program. It began with a clear shared vision and purpose, and a new strategy underpinned by a success scorecard and strategic roadmap. We then defined and measured both current and aspirational culture and leadership capability, giving the business a baseline to work from. Culture change and leadership development programs ran across the executive and senior leadership teams to bring the strategy and the behaviours to life, alongside targeted work to increase cross-functional collaboration and co-design communication plans.

The Outcome

Employee engagement reached 75%, organisation-leading. Contact centre engagement hit 83%, sustained through the 2022 pandemic period. Customer complaints fell 60% over three years.
