Infosys problem is that they have built a strong corporate culture and no leadership chain to pass the baton.
I will explain in detail:
In the book "In Search of Excellence" Tom Peters and Robert Waterman explain that strong corporate culture imbibed with ethics makes the recipe for top companies. In such companies because of inbuilt culture, outsiders do not survive. One classic failure is Carly Fiorina who could not handle HP successfully despite being a great leader and competent decision maker. Infosys built such a culture which is good. But those companies need a steady stream of CEO supply from inside. This is where Infosys failed. Although Narayana Murthy always claimed that his company is not a family enterprise and is a professional company blah blah blah., the founder team never let the next rung leadership grow. The founders are always publicity hungry and media savvy. Since they ran out of managerial talent, they brought in Vishal Sikka. The guy is competent, but Infoscions do not like to report to him because he brings in a different culture. Our publicity hungry Narayana Murthy lent credence to the team with its antics and they booted Vishal Sikka out. Till date they could not prove Vishal Sikka guilty of corruption. A retired founder who is equally publicity hungry steps in to douse the fire. ( This is similar to a national party bringing back an old lady as its president.) Then they hire Salil who comes from a different corporate culture. And the story repeats. Our media savvy promoters invoke God and his capabilities regarding fudging of Infy's accounts. This has become a comedy show with the company. I look at this as a serious leadership problem. If this is not fixed, it could weaken the company and eventually it may get absorbed (merged) in a competitor company and then the moles causing trouble will finally be booted out. Though the promoters will try to see that this does not happen, they are responsible for this situation, Every retired promoter pokes his nose into the corporate affairs of this company emboldening the subordinates to challenge the CEOs. The only way promoters can save their investment in this company is to let it merge with another similar company. Retired guys should step aside and settle down to watching the grass grow.
On a side note, TCS is not so media savvy, and, they do not make tall claims on corporate ethics, and, they are silent performers.
