Look the problem is with the Hitachi Japan, It is hiring /approving/promoting executives without doing any proper background check of their merits and accomplishments.
The problem is wide spread in industry today. It is difficult, even for a technical Genius to say his/her product/achievement is making $ billions to the company in linked in profile where as a sales/ marketing executives ( like GK) can say "Increased run-rate from $160 million annually to more than $1 billion in three years". see the other Hitachi executives profiles for better jokes.
Without a proper tools to check credibility of these executives and their individual worth instead of their claim of collective worth of the group they head, driving the good company to dust.
To all the good, struggling companies like Hitachi Vantara here is my humble request to Japan
1) Hire executives and give benefits/compensation/raises to the executives based on their individual merit than the collective claims.
2) A wrong direction of an individual employee is less expensive than an executive, So evaluate the performance of every executive quarterly instead of giving them a blanket time of 2/4 years.
hire them on a term basis.
3) Put your managers/executives to test, by putting their direction/accomplishment in a 360 degree peer review of all their employees & peers and provide them raises only after 100% agree.
4) Change all your executives to persons from an engineering background not an MBA and see the change. A non engineering executives making an engineering decision is the cause of demise of many good companies.
Thanks,
