My experience after multiple IBM RAs, is that they don't understand, don't care or expect breakage and assume someone will figure it out.
IBM mode of operation for the past 15 years is cut higher paid resources in the US and move jobs to India. Every RA I have been involved in as a manager is a numbers exercise, just like IBM budgeting, each division is given a number. I believe that the big number each division is given is based on the current or projected profit/revenue of that division. Within the division, they make decisions based on their projections/plans and determine project/team cuts and percentages for each org/team. The manager should be the final decision maker on which people, but I have heard of cases where that is not the case. So they cut and see where the pieces fall.
The historical issue is that projections are typically wrong and they look ignorant after the fact. Good examples are stated projected growth in Cloud, AI, Watson Health, etc... Ginni was very proficient at pivoting and twisting failure into a success message and stating a somewhat new, somewhat the same, message of the future. Always in a list of 3 things.
While Arvind is a new CEO, he comes from the IBM culture and the people he is relying on are the same people Ginni worked with. They always go back to the same playbook and add a twist when they can. They DO NOT want to communicate numbers of layoffs, number of people employed in each country, etc... If it truly were a skills shift, than why wouldn't they be willing to do that? As a general rule, if you are doing the right thing, you are willing to share that.
This culture won't change until there is a new board and new executive team, hired externally. The culture is too strong. Jim W may be some peoples hope, but one could argue he is being assimilated.
With IBM's cash and declining revenues, it's not unrealistic to think IBM could be purchased or taken over and split up into smaller companies, including RedHat, and sell off the pieces. In a normal economy it would be worth more that way.
