Strengthening internal coaching capability and demonstrating its organizational value

T-Mobile engaged CEC Global to provide coaching supervision for its internal sales enablement coaches and consultants.

Coaching within a large organization brings particular professional and ethical complexities. In supervision, coaches worked on how to balance confidentiality and transparency with clients and managers, and work effectively across long-term coaching relationships and situations where clients could have more than one coach.

The team was also supporting clients working through difficult and sometimes HR-adjacent conversations, questions around resistance and readiness for change, and an increasingly important organizational question: how to demonstrate the ongoing value of coaching to the business.

Alongside these day-to-day challenges, the coaching function itself was evolving. Organizational restructures contributed to broader roles combining coaching, training and consulting, alongside a move toward group and team coaching to support greater scale.

The requirement was therefore broader than individual coach development. T-Mobile needed a confidential, professionally rigorous space in which coaches could strengthen judgment and practice, while the team continued to evolve its capability and consider how the value of coaching could be understood across the organization.

CEC provided regular virtual group supervision, serving the normative, developmental and restorative purposes of supervision in a confidential forum where coaches could reflect on their work, explore live case consultations and examine difficult professional and ethical questions together.

“Our supervisor was particularly instrumental in helping our team navigate complex coaching scenarios and difficult client situations. Her nuanced understanding of coaching ethics, human behavior, organizational dynamics, and coaching best practices enabled her to help us think through challenges with greater confidence and professionalism. Time and again, I left our supervision sessions with practical insights that immediately improved my coaching effectiveness.”

Frameworks including the 7-Eyed Model helped coaches step outside individual coaching conversations and consider cases from multiple perspectives. Sessions were grounded in situations the team was encountering in practice, enabling supervision to respond directly to the realities of coaching inside a large organization.

Structured peer approaches were also used to deepen collective learning. In one “From the Balcony” session, a coach brought a live case for structured peer commentary, with facilitation and reflection helping the group examine the situation from different perspectives.

Group supervision was complemented by regular individual consultation with the team leader, who held responsibility for coaching and consulting strategy as well as the quality and development of the internal coaching team. Supervision supported the broader development of the team, including conversations about the value of accreditation for internal coaches.

As the organization and team evolved, CEC adapted the supervision accordingly, supporting coaches as their roles broadened and their work expanded into group and team coaching.
