Most technology projects in our markets do not fail on specification. They fail somewhere between the purchase order and the loading bay.
A specification is the easy part. What decides whether a project lands on time is whether the paperwork matches the goods, whether the vendor understands the documentation the destination requires, and whether somebody is accountable when a container sits at a border for a fortnight.
The practical lesson we keep relearning: treat customs documentation as part of the technical specification, not as an administrative afterthought. Get the HS codes, the certificates of origin and the end-user documentation agreed before the order is placed, not after the shipment moves.
