Y’all… I did it! On December 4th, I defended my dissertation and passed with no revisions. After a long stretch of grit, determination, and hard work, this chapter is finally complete.
I put together this reflection for anyone curious about the study, what I learned, and why it matters for leaders, teams, and organizations trying to make real, lasting change.
What My Study Was All About
My research explored how transformational leadership behaviors influence employee buy-in and the long-term sustainability of change initiatives—specifically within Lean Six Sigma (LSS) projects.
Lean Six Sigma gives organizations the data-driven tools to solve problems… but tools don’t create buy-in. People do.
What my study revealed is that the human side of change can make or break a change initiative and determines if the change initiative is sustainable.
My study included:
- A quantitative survey measuring transformational leadership, employee buy-in, and sustainability
- One focus group that offered real-world stories and insights
- Triangulation of both sets of data to strengthen conclusions
My Key Findings
After analyzing the data, running the stats, and coding the focus group transcript (plus collapsing 36 themes into 10, and then down to the 4 strongest ones), here’s what rose to the top:
1. Transformational Leadership Strongly Predicts Sustainability
Leaders who communicate clearly, build trust, recognize their people, stay visible throughout change, and model the behaviors they expect are the leaders whose projects sustain over time.
In short: You can’t “set it and forget it.”
Ongoing leadership presence matters.
2. Employee Buy-In Matters… But It Isn’t Enough Alone
This one surprised me.
Even when employees supported the change, buy-in by itself did not guarantee long-term success. Projects fizzled without systems of accountability and continued leadership support.
Buy-in opens the door, but leadership walks the team through it.
3. Trust and Visibility Are the Glue
Both quant and qual data pointed to this truth:
Teams follow leaders they can see, hear, and trust.
People were more willing to adopt new processes when leaders:
- Showed up in the workspace
- Explained the “why” behind decisions
- Checked in regularly
- Celebrated quick wins
Visibility isn’t micromanagement; it’s relationship building.
4. Communication and Clarity Keep Projects Alive
When goals, expectations, and responsibilities were unclear, sustainability suffered.
When leaders communicated frequently and in simple, consistent language, teams stayed aligned.
Good communication is oxygen for success.
The takeaway?
Even the best tools can’t overcome persistent organizational barriers without leadership commitment.
What Does All This Mean for Organizations?
Here’s the big message my study drives home:
To make change initiatives sustainable, organizations must integrate strong, relational leadership behaviors within the change management framework.
It’s not an either/or.
It’s people + process.
It’s relationship + rigor.
It’s human leadership + analytical discipline.
When leaders combine those two worlds, change sticks.
What This Journey Taught Me Personally
Beyond the academic findings, the whole process reminded me:
- Leadership is personal.
- Trust can’t be automated.
- Data might tell us what is working, but people tell us whether it will keep working.
After plenty of moments where I wondered if I’d finish at all, this study taught me something else: Perseverance works.
Supportive people matter.
And dreams don’t have deadlines.
