Consultancies know less than they claim and cost more than they seem to
You can see this in all areas of life.<p>NYC has huge problems with transit capital projects because they basically have zero in-house expertise, from project planning down to digging the tunnels.  This despite having decades of multiple continuous projects going since the 90s and onwards.  It&#x27;s all outsourced, and the state gets ripped off because they don&#x27;t have the capacity to plan, or to cross check the outsourced plans, etc.<p>In tech you see this all the time when senior management wants to move into some area that isn&#x27;t a core competency and brings in their buddies outsourcing consulting body shop.  The POC period skates by because everyone implicitly understands the consultant was brought in from the top.  They then outsource the actual work to a 24 year old in a shiny US office to project manage 10 offshore 24 year olds.  No one has any idea what they are doing, nothing gets done, and a few million go out the door.
