1. No pre-engagement interview process for engineers Thoughtworks operates a policy of not allowing clients to interview engineers before they join an account, on the basis that all their people meet a consistent standard. In practice, this did not hold up. We found ourselves with individuals who were not the right fit for the account, with no prior opportunity to identify that. Replacing people mid-engagement is disruptive and costly, and the policy felt like it prioritised Thoughtworks' operating model over the client's needs. 2. Value for money across the full delivery team Thoughtworks commands premium pricing and, at the senior consultancy level, that premium is justified. However, a significant portion of the engineering delivery is resourced from India, and while there were standout individuals in that team, overall performance at that level did not consistently match the standard we achieve with near-shore alternatives at comparable or lower cost. When you are paying for the Thoughtworks brand, you reasonably expect that standard to hold across the engagement. It does not consistently do so. 3. Day-to-day delivery challenges Delivery was competent but not without friction. There were enough recurring challenges during execution to prevent us rating this area any higher than average. None were catastrophic, but the cumulative effect was that the delivery experience felt no different to working with a standard supplier, which is a missed opportunity given the premium positioning and the strength of their consultancy work.
