HAHAHAHHAHA close legs
i get what you are trying to say but let me add color to your comment.
the skills change ?? in what ? i guess you imply people ??? well that not a big deal really as ibm and other companies have active programs to keep skills up to date and in the case of IBM they lead the way in skills (they have the most patents)
Management looks at the company from the point of view to make good on shareholder promises so they can get rich with their incentive compensation. Management uses what they call LEVERS to get to the PPS they need. the levers are Employees, R&D, Pricing of current products & Services, Bring new products & services to market, Stock buy backs.
By adjusting the levers to market conditions they can get the PPS they want. The real problem with IBM is the size - they have to grow so much due to the size which is tough. The other problem IBM is facing is competition (which they always have). IBM can beat the new competition by providing a complete solution as opposed to a single product or service.
