When a technical system breaks, you don’t just look for bugs in the application layer; you debug the whole stack.
The Leadership Stack applies that same idea to teams: It’s a way to reframe squishy human problems as system bugs.
How it Helps
Even though people problems show up in the application layer, debugging them there rarely works. At best it leads to short-term results. It also creates team friction that slows you down. At worst, it leads to disengagement, burnout and a toxic team culture.
The Leadership Stack helps you find where the bug originated. Then you and your team can work together to solve the problem for good, instead of wasting your energy pushing against each other.
Debugging the Leadership Stack
Each layer of the Leadership Stack builds on the layer below it. Bugs higher in the stack are easier to identify, but are often rooted by more subtle bugs deeper in the stack. Visualizing where a bug originates helps leaders decide where to focus their debugging efforts.
Application Layer
Sometimes referred to “the real work.”
This is the layer where Individual Contributors most commonly work, but very few human systems problems can be debugged directly from this layer.
Bugs in this layer include:
- Missed deadlines
- Buggy releases
- Functional misalignment
Interface Layer
Instead of stitching bits of code together to form a cohesive code base, leaders create systems and processes that connect the efforts of each team member so they are working together toward a common goal.
Bugs in this layer include:
- Miscommunication
- Dropped or duplicated work
- Poorly distributed workloads
- Neglected administrative or maintenance work
Data Layer
Unlike the normalized databases you worked with as a software developer, the data layer of the leadership stack is comprised of the information stored in the brains of your team members. Leaders ensure the necessary data is available, accurate, and up-to-date.
Bugs in this layer include:
- Over or under engineered solutions
- Difficulty transitioning to new procedures or priorities
- Proposed solutions fail to meet business requirements
Permissions Layer
In codebases and in life, complex systems have elements you can see but not change (read access), elements you can see and change (read/write access), and elements that are totally invisible to you (unless you are a sys admin). When your team doesn’t have the permissions required to do their work, leaders find ways to bridge the gap.
Bugs in this layer include:
- Team lacks the information or resources required to meet its goals.
- Effort spent focusing on what others need to change blocks progress the team could make on their own.
- The team is responsible for an outcome they don’t have the power to influence.
Security Layer
This is where all the emotional stuff lives. Each member of your team (including you) runs their own private security network that automatically responds to real and perceived threats to psychological safety. Leaders help team members identify when their security system has been triggered, what triggered it, and what is needed to clear the threat.
Bugs in this layer include:
- Reluctance to share bad news
- Resistance to feedback
- Focus on blame/ CYA behaviors
- Miscalibration around risk
- Oversharing
- Lack of proactive action
Operating System Layer
Operating systems dictate what gets prioritized, what is allowed, and what gets blocked. In human systems there are documented rules (like the employee handbook) and undocumented ones (like if you say it’s an AI project, your budget will be approved). Effective leaders learn to navigate both so their team gets the support and resources needed to achieve their goals.
Bugs in this layer include:
- Organizational goals change faster than projects can be completed
- Objectives are interpreted differently across the organization
- Expectations are enforced inconsistently
- Institutional knowledge is shared primarily by oral tradition
- Organizational documentation and operational reality contradict each other
