Building fitness for change in organizations that live with uncertainty
Adaptive Ways explores how organizations build fitness for change.
Through the Adaptive Fitness System (AFS), essays, and field reflections.
The AFS is a way of thinking about fitness, a system for noticing when it no longer holds, and a toolbox for turning evidence into purposeful adaptation.
Most organizations don’t struggle because they lack methods or ambition. They struggle because change rarely enters a stable environment. Purpose shifts, constraints tighten, and context moves faster than plans. What matters then is not strength but fitness: the ability of a system to adapt without losing coherence.
I’m Mario Aiello, and Adaptive Ways is where I work out how that fitness can be understood, tested, and sustained, drawing on years of working inside large organizations in the middle of change.
The idea
At the center is the Adaptive Fitness System, an approach built on one rule, the Governing Law: fitness is proven, not presumed. Before installing a solution, we should understand whether it can survive the system it is entering. The Fitness Sequence puts that into practice through the Four Questions: is the change Fit for Purpose, Fit for Context, Fit for Execution, and Fit for Improvement?
AFS isn’t something to roll out. It’s a lens that helps leaders and practitioners ask better questions about change, adoption, and organizational health.
Where to start
New here?
Start here is a short introduction to the thinking behind Adaptive Ways.
The AFS lays out the approach itself and how its components fit together.
If you’d rather meet the idea before the theory, The AFS Casebook is forty-five illustrated scenes, four familiar characters, and one inconvenient idea.
Once you have the shape of it, The AFS Library is where the approach is tested against real cases, other methods, and its own claims, series by series: the Governing Law, the Four Questions, Presumed Fit, Borrowed Fitness, Hidden Misfit, and the Critical papers.
The Archive (former agileways.blog) holds the earlier reflections that shaped this work, from when the site was still agileways.blog.
Open for Review
Self-critique isn’t the same as being critiqued. I’ve spent the past year writing papers that try to break AFS, and Open for Review collects them, along with the foundational material you need to know what’s being critiqued. It’s there so that someone with no reason to go easy on the approach can tell me where it doesn’t hold.

Adaptive Ways is not a finished doctrine. It’s an evolving exploration of how organizations remain viable in motion. The ongoing essays live on Adaptive Ways on Substack; this site holds the canon.
