I think Randy made couple of mistakes in insourcing in GM, and it might collapse. I got a strange feeling he is building a typical IT company across GM, forgeting he's a CIO of the automotive coorporation, with business spread across the globe. People insourced on new positions are not having any experience in automotive industry at all, nor the experience with other regions outside of the US. This is leading to much stronger separation between GM business and GM IT and at the end it might destroy all relations that have been already built between IT and business. This is a point where Randy and his ex-HP and ex-DELL guys forgot that business owns the company, not IT. Business rates IT as well. Somebody mentioned about Shadow IT. According to me, Shadow IT was an answer on a weak performance of an IT organization in general. If business couldn't get from IT what they want, they are going to suppliers leaving GM IT and all is done, working without issues, without tons of documents, processes, analysis. I think Randy's organization will be hit again with Shadow IT, when the business will get angry about delayed projects, non-working apps, forced centralized apps with a limited business engagement lead by typical IT PMs with no idea about markets and business needs. That will be the first step the system is failing. Additionally when those projects or apps will have errors and for another year IT will be fixing it up, the level of business aggression which is quite high today will reach the top and the transformation will be over.
I think the general idea of Randy's strategy is worth trying, but not in the automotive industry, but he's doing too many things in one time in huge organization where the intertia between top and bottom might be even 1 year. I can belive he was an expert 30 years ago knowing the Walmart business across US, but I doubt if he's experienced automotive person across all the globe with multi-continental automotive regulations. Cars are not the same as a pop-corn, and I think he's treating this business this way. HP is still returning to the model before transformation. Have no idea about DELL, but I keep the fingers crossed. I'm giving personally 1 year - big success or failed transformation with huge mess... 3rd time in a row?
