An intranet is cheap to launch. It's expensive to keep alive.
Every Microsoft 365 update sends an unannounced bill for whatever was built custom on top of it. According to Deloitte's latest technology leadership study (2026), technical debt absorbs between 21 and 40% of an organization's total IT spend. This webinar, run with Avanade, isn't about the intranet you build. It's about the one you maintain, and what it really costs over three years.
What you'll walk away with
- How to calculate the real TCO of an intranet, beyond the initial quote
- An unfiltered comparison of the three approaches on Microsoft 365: off-the-shelf, custom-built, turnkey
- The warning signs of an unplanned maintenance bill
- A three-move method for exiting a competing technology, without a prolonged double run
- A scoping method to take away, not just a product pitch
Who this webinar is for
This webinar is for:
- CIOs and CISOs running an M365 environment
- Heads of Communications and digital workplace leads
- Any organization in growth or transformation (merger, new tenant, exit from a competing solution)
👉 A webinar to move past the off-the-shelf-versus-custom debate, and look at what an intranet really costs over three years, with Aimery Thomas and Jean-Baptiste Wirth (Avanade) and Antoine Billard (Jint).
