TMS Development International (TMSDI)

Individual, team and leadership development
 
Stronger teams, smarter leaders, sustained success

TMSDI was founded over 35 years ago with a simple purpose: to help people and teams work better together. Based in York, we’ve built a reputation for providing practical, research-based development tools that enable individuals, teams and leaders to understand themselves, collaborate effectively, and deliver real results.
 
Feedback profiles developed with, and for, managers

We specialise in tools that focus on real workplace behaviours and preferences:

• Team Management Profile (TMP) - explore personal work preferences and team contribution
• Opportunities-Obstacles Quotient (QO₂) Profile - understand how people respond to change, risk and uncertainty
• Linking Leader Profile (LLP|360) - develop leaders who connect, perform and inspire
• Window on Work Values (WoWV) Profile - reveal the personal values that drive motivation and workplace behaviour
• Leadership Behaviours Profile (LBP) - enhance leadership effectiveness for emerging and established leaders
   

These profiles are widely used in leadership development, team building, coaching, organisational change and cultural alignment. Each provides clear insights and practical strategies that can be applied straight away, delivering impact across sectors.
 
Valuing diversity

At the heart of our approach is a development framework that recognises and values different perspectives. It encourages an environment where people feel heard, contributions aren’t overlooked, and leadership potential is identified at every level.
 
Supporting clients across the public sector

We’re proud to work with central and local government, the NHS, utilities and a wide range of agencies. Wherever teams need to perform under pressure, our tools provide the clarity and shared language to build trust, reduce conflict and focus energy on what matters most.
 
Develop your in-house capability…

Our flexible accreditation programmes equip L&D professionals with the knowledge, confidence and practical skills to use our feedback profiles effectively.

…or let us deliver for you

For organisations that prefer direct support, our in-house team can design and deliver tailored programmes built around your specific goals and challenges.
 
Why TMSDI?

Big impact doesn’t require a big team. We work closely with clients as an extension of their own, combining proven tools with expert, responsive support to help leaders and teams unlock potential, manage change and deliver lasting results.
