These six case studies show how organizations used a shared language, self-awareness, and practical development processes to strengthen collaboration, navigate change, and improve business outcomes.
In short
- Six real-world leadership and team development case studies, created by Insights, DEVELOR’s strategic partner
- Examples from healthcare, travel, retail, construction, and food
- Practical lessons on change, team effectiveness, inclusion, and commercial performance
What makes leadership and team development effective?
Effective development is not a one-off workshop. It connects individual insights with real business challenges, provides a shared language, and creates opportunities to practice new behaviors.
The cases below show several principles that HR and L&D leaders can apply:
- Start with a clearly defined organizational or team challenge
- Help people understand their own preferences and impact
- Connect self-awareness with communication, leadership, and collaboration
- Build internal capability so learning can scale
- Reinforce learning through action plans, team routines, and follow-up
- Measure both behavioral and business outcomes where possible
6 leadership and team development case studies
Each case study demonstrates a different application of behavioral awareness, from supporting relocation and global transformation to developing apprentices and improving financial performance.
Navigating organizational change at Danone
When Danone relocated its Early Life Nutrition business, the organization needed to manage both logistics and the human side of change. Insights Discovery helped employees understand their reactions, adapt their working styles, and form effective new teams. The language of color energies became embedded in everyday communication, supporting a more agile organization.
Building high-performing global teams at Expedia Group
Expedia Group was transforming into a platform business while more than 18,000 employees across 50 countries navigated reorganization, remote work, and new team identities. A bespoke Team Effectiveness solution helped teams challenge assumptions, identify collective strengths, and create clearer agreements for working together across cultures and functions.
Developing cross-stream collaboration at Northumbria Healthcare
As Northumbria Healthcare’s Public Health team grew, separate workstreams needed a stronger shared identity and clearer collaboration. Two development days combined Insights Discovery, team reflection, and action planning. The result was greater trust, shared ownership, and a practical roadmap connecting individual roles with the wider Public Health strategy.
Maximizing workforce potential at Specsavers
Specsavers introduced Insights Discovery across Northern Europe to strengthen collaboration and bring its values of curiosity, compassion, and collaboration into everyday behavior. Personal profiles, workshops, and internal accredited practitioners helped geographically dispersed teams reduce friction, communicate more openly, and appreciate different working styles.
Tackling the skills shortage at Travis Perkins
Travis Perkins transformed a successful internal apprenticeship program into an industry-wide solution. Insights Discovery became the “red thread” supporting communication, adaptability, and leadership development. The program reached employees in more than 20 organizations, while 40% of new recruits were female and 85% achieved a merit or distinction.
Improving branch leadership and financial performance at Wolseley
Wolseley co-developed the Leading Yourself program for first-line branch managers across its national network. The initial ten-manager pilot generated a £172,000 return on a £29,440 investment, yielding a 484% ROI. The program later expanded to around 200 managers and helped position L&D as a strategic contributor to commercial performance.
What can HR and L&D leaders learn from these examples?
The six organizations faced different business problems, but their development journeys shared a consistent logic: awareness was connected to action.
Danone used it to support change. Expedia Group and Northumbria Healthcare used it to rebuild collaboration. Specsavers connected it to organizational values. Travis Perkins embedded it in early-career development. Wolseley linked leadership behavior directly with financial outcomes.
The Insights Discovery Personal Effectiveness program creates the individual foundation, while Insights Discovery Team Effectiveness helps teams apply that awareness to shared performance.
Insights has been DEVELOR’s strategic partner for more than 25 years. Together, we help organizations turn behavioral awareness into stronger leadership, collaboration, and measurable workplace impact.
Frequently asked questions about leadership and team development case studies
Leadership development case studies show how learning is applied to real organizational challenges. They can demonstrate changes in manager behavior, team relationships, customer experience, operational performance, or financial results. They are most useful when they explain the initial problem, the intervention, and the outcomes. HR and L&D teams can use them to identify practices that may transfer to their own organization.
Start by linking the program to a measurable business need before development begins. Relevant indicators may include employee retention, customer satisfaction, productivity, sales, costs, or team effectiveness. Behavioral evidence should also be collected through observation, feedback, and follow-up.
Self-awareness helps people understand their preferences, strengths, triggers, and impact on others. Other-awareness helps them recognize that colleagues may communicate, decide, and respond differently. A shared language makes these differences easier to discuss without judgment. This can reduce friction, improve collaboration, and help teams adapt their collective behavior.
Scalability often requires internal capability. Accredited practitioners can deliver workshops, support teams, and reinforce a common language without relying solely on external facilitators. Specsavers, Wolseley, and Danone used internal practitioners to embed development across locations and over time. Consistent tools and flexible applications also make expansion easier.
Yes. Team development can help people understand their reactions to change, rebuild trust, and create new working agreements. This is especially important when roles, structures, or team identities are changing. The Danone and Expedia Group cases show how a shared behavioral framework can give people continuity and practical language during transformation.
Sustainable programs continue beyond the original workshop. They include action planning, regular reflection, manager involvement, and opportunities to revisit personal or team insights. Learning should become part of meetings, feedback, and daily communication. Internal facilitators and a clear connection to business priorities also increase long-term relevance.
