Scrum Masters are Glue Roles

A while ago, John Cutler described the Scrum Master, Agile Coach, and other similar roles (which I can’t recall anymore) as glue roles. It caught my attention, and I made a mental note to explore the idea further when I had more time.

A quick search led me to this definition: "A glue role connects different parts of an organization, ensuring smooth team communication, collaboration, and integration. These roles are essential for implementing change and solving systemic issues that impact multiple departments."

It’s easy to see the connection to the purpose of a Scrum Master or Agile Coach. Let’s stick with the glue metaphor a little longer. 😉

Here are a few thoughts it sparks:
🎈 Without glue, it’s difficult to connect parts.
🎈 If you don’t use enough glue, things won’t stick.
🎈 Low-quality glue might work in the short term but fails over time.
🎈 Removing strong glue can be tricky—and might cause damage.
🎈 Some glue requires patience; things need time to set correctly.
🎈 Beware of super-glue promises—they have their limitations.
🎈 When the glue is invisible, its value can be overlooked.

These ideas map directly to the roles of a Scrum Master and Agile Coach. But how do you become an effective glue in your organization? Here are a few practical ways to make your impact stick.

🛠 Use the right glue for the situation
Not every challenge requires the same kind of support. Sometimes, teams need fast-drying glue (decisive action and clear guidance), while other times, a more flexible adhesive (facilitation and patience) is the best fit. Adapt your approach based on the context.

⏳ Give things time to set
Change doesn’t happen overnight. High-performing teams don’t magically form after a single retrospective or workshop. Support their growth without rushing the process, and allow trust and collaboration to develop naturally.

📏 Apply the right amount
Too much "glue" (micromanagement) can create resistance, while too little (hands-off coaching) might leave teams disconnected. Find the balance between stepping in when needed and giving teams the space to self-organize.

🕵️‍♂️ Make the invisible visible
One of the challenges of being the glue is that people often don’t notice it—until it’s gone. Find ways to highlight your impact without making it about you. Share success stories, showcase team improvements, and help leadership see the long-term value of your role.

🔄 Check for wear and tear
Even strong glue weakens over time. Team dynamics shift, priorities change, and external pressures evolve. Regularly inspect how well things are holding together and reinforce where necessary. Proactive coaching prevents cracks from turning into full-blown fractures.

Scrum Masters and Agile Coaches often work behind the scenes, but their impact is undeniable when they play their role effectively.
