Sikka, a former Board member of German software giant SAP, took over as the CEO of Infosys last week. He is the first outsider and non-founder CEO of the country's second largest software services firm.
"The news of Sikka's announcement is extremely important for Infosys since it ends the uncertainty that was the main enemy of Infosys. The new CEO will have to move very quickly to first calm the three key stakeholders, employees, customers and the investors, in that order," Gartner Research India Country Manager Partha Iyengar told PTI.
Infosys cannot afford any more resource departures especially at senior levels, he added.
Sikka, 47, previously headed technology and innovation at SAP and created analytics product HANA.
Once the IT bellwether, Infosys in the last couple of years has been reporting laggard performance, facing harassment allegations by overseas employees, top level exists, among others.
Its employee attrition hit a record high of 19.5 per cent in the April-June quarter of 2014-15, up from 16.9 per cent in the year-ago period.
For 2014-15, Infosys retained its conservative revenue guidance of 7-9 per cent in dollar terms and 5.6-7.6 per cent in rupee terms, much below Nasscom's industry growth outlook at 13-15 per cent in dollar terms.
All this at a time when its peers like TCS and HCL Technologies are reporting stellar performances.
"He will have to establish credibility with those stakeholders again, in a fairly short period and then energise them in the medium to long term. The medium term strategy will have to be fairly close to the knitting of the IT services industry, anything else will create a level of confusion and uncertainty again," Iyengar said.
Greyhound Research CEO Sanchit Vir Gogia feels though the firm is showing signs of recovery, it's still too early to say if it is in full swing and the new CEO has a lot on his hands.
"Vishal Sikka is stepping in at a time when Infosys is at a crossroads. The company has lost a lot of key people at the senior management. There are signs of recovery but we cannot say that the recovery is in its full swing yet. It's a tough position to hold and a tough job at hand. Vishal has got lots of ground to cover," he added.
UK-based research firm Tech Market View Managing Partner Anthony Miller also feels Sikka should focus on employees.
"In my view, Sikka should rather be spending that disproportionate amount of focus on the core bread and butter businesses and address Infosys' rampant attrition, because until those are fixed the rest is really just a sideshow," he said in a post.
