Sikka, who looked prepared for his next assignment, said: "As I write this, I am looking forward to taking leadership responsibility on August 1, and looking forward to a great transition that must follow my little transition. A great transition and its set of challenges and opportunities that await my new company, as well as every company in our industry, and indeed as software reshapes the world around us, every company in the world."

Sikka said he has been through two "transitions" in the last eight weeks, which have been "surreal".

"I've been through two extraordinary transitions within a period of time that feels like an instant. And at the same time, these two transitions happened amid the backdrop of much bigger transitions and transformations, that organisations go through, from companies to countries," he added.

Transformations they must go through, to survive, to continue to be relevant, when the circumstances and contexts around them change dramatically, Sikka said.

Fining similarities between his journey and India's (the country has voted Narendra Modi-led BJP to power in May) Sikka said his homeland has also witnessed a transition.

"And at the same time, my maternal homeland India has just seen a great transition of its own, and more than a billion citizens find themselves hopeful and looking ahead to a great transformation under a new transformative leadership," Sikka noted.
