Quick Lessons
Short, focused lessons you can apply today.
AI-Assisted IT Support & Automation
AI will not replace your service desk. It will quietly hand the keys to whoever forgets to keep a human in the room.
AI Tutors & Personalized Learning
For forty years we have known one-to-one tutoring works almost magically well, and we could never afford it. Large language models change the math - but only if we remember that the model was never the teacher.
AI Tools for Project Managers
I was skeptical that an AI could help me run a project. A year later it drafts half my paperwork - and I trust it less than ever, in the best possible way.
Supporting Hybrid & Remote Workforces
The office help desk assumed it could walk over and fix things. When the users scattered, the service desk had to be rebuilt around a single uncomfortable truth - you can never touch the device.
Backup, Recovery & Data Protection
Everyone has backups. Almost nobody has restores. Here is the difference, and why it decides whether a bad day becomes a catastrophe.
Coaching & Mentoring Engineers
The senior engineer's hardest promotion isn't to staff - it's from being the person with the answers to the person who grows the people who have them.
Measuring Training Effectiveness (ROI)
Most training is measured by accident - attendance, smile sheets, hours delivered. Here is how to prove what learning is actually worth, and why the conservative number wins.

Most teams don't lack ambition - they lack a finish line. Here's what changed when mine started writing goals we could actually score.
Leading Remote & Distributed Teams
The hardest part of leading people you never see is unlearning everything the office quietly did for you.

Every support engineer hits a ceiling doing things by hand. Scripting is how you break through it, and you only need two shells to start.
ITSM & the Service Desk (ITIL)
The service desk is the most underrated team in IT. Run it as a service, not a switchboard, and it quietly makes the whole organisation better.
Building an Online Course
Most online courses fail not because the teaching is bad, but because they were never designed to be finished. Here is how to build one that is.
Recording Great Video Tutorials
The gear matters less than you think. Here is what actually separates a tutorial people finish from one they abandon.
Hybrid Agile + Waterfall Delivery

A Comprehensive Guide to Hierarchical Planning in Production and Supply Chain Management
Production and supply chain management require a structured, multi-level approach to planning that ranges from strategic decisions to daily scheduling.
Project Budgeting & Cost Control
Why the question "how much have we spent?" is the least useful thing you can ask about a project budget - and what to ask instead.
