Whoever thinks that a CIO's job is easy has no idea of the challenges that trouble the IT department. With the ever-changing technology landscape and increasing expectations from LoBs, these challenges are hanging like a sword over CIOs' head.

According to the State of the CIO 2015 survey, 49 percent of Indian CIOs, across verticals, are grappling with inadequate in-house skillsets in areas like cloud computing, virtualization, mobility, BI and analytics, and security. Forty-three percent worry about delayed decisions from business. And funding of new IT projects is another cause of concern for 39 percent of CIOs. These are the top three challenges of Indian CIOs.

But when you drill this down sector-wise, you'll find that different verticals are facing different challenges. For example, the biggest challenge for CIOs in the BFSI sector is governance, risk and compliance (GRC). A majority--59 percent--of BFSI CIOs say GRC is a challenge. However, for CIOs in the auto sector, offering hard, tangible ROI for every new IT project is the biggest challenge.

On the other hand, 48 percent of CIOs in the manufacturing sector say delayed decisions from business is their biggest challenge. Apart from this, funding new IT projects and a lack of in-house skillsets trouble 44 percent and 43 percent of manufacturing CIOs respectively.

The CIOs in the IT/ITeS vertical aren't spared either. Mobility and cloud computing are the trends earmarked by CIOs for 2015 but a lack of skillsets in these areas upset 54 percent of them. Additionally, finding funding for new IT projects is a daunting challenge for 46 percent of IT/ITeS CIOs.

Do you still believe that IT departments' job is a cake walk? Well, think again.
