Which Methodologies for Which Projects?
Choosing the right way to deliver in complex IT environments
By Duncan Sinclair
Most IT projects don’t fail because of bad people or bad tools.
They fail because the wrong methodology was applied to the wrong context.
Cloud migrations, ERP rollouts, data platforms, AI pilots, cybersecurity programmes, multi-country deployments… each type of project comes with its own mix of risk, uncertainty, regulation, and organisational politics. Asking “Agile or Waterfall?” is no longer enough.
This book helps you ask a much better question:
“For this project, in this organisation, what is the smartest way to deliver?”
What this book will help you do
Instead of selling a single “universal” framework, Which Methodologies for Which Projects? gives you a practical decision-making toolkit to match delivery methods to real project situations.
Inside, you will:
Understand the true strengths and limits of the main approaches:
Waterfall, Scrum, Kanban, Hybrid models, Lean, Six Sigma, DevOps and scaled Agile.
Learn how to analyse your project context: risk, uncertainty, dependencies, compliance, suppliers, team maturity, geography, and politics.
Use a Methodology Selection Matrix to compare options and justify your choice to sponsors, PMO and auditors.
See how different methodologies behave on real projects:
ERP & finance systems, cloud migration, data/BI programmes, integration projects, regulated environments, and multi-vendor landscapes.
Combine and tailor methods in hybrid setups that actually work in large organisations (instead of “textbook Agile” that collapses after the first steering committee).
Reuse concrete tools and templates:
– comparison tables
– decision grids
– governance patterns
– examples of how to present methodology choices in slides and reports.
Who is this book for?
This book is written for professionals who live in the real world of constraints, legacy systems, and conflicting stakeholders:
IT Project and Programme Managers
PMO leaders and analysts
Product Owners, Scrum Masters, Agile Coaches
Enterprise and Solution Architects
CIOs, IT Directors and transformation leaders
Whether you work in a global corporation, a mid-sized company, or a complex multi-supplier environment, this book will help you turn methodologies from ideology into a strategic lever for project success.
