Like any new relationship, there's a lot of initial awkwardness. For example, some marketing and IT executives may have trust issues and may not want to share responsibilities equally. According to “CMOs and CIOs Can Accomplish the Extraordinary Together,” a presentation by Gartner Inc.'s VP of Research Laura McLellan during the Direct Marketing News Marketing&Tech Partnership Summit 2013 (sponsored by Bizo), 71per cent of those surveyed said marketing determines the need for marketing technology, compared to 14per cent who cited IT; and 67 per cent said marketers set the marketing-tech strategy (versus 13 per cent who claimed this responsibility falls on IT. Likewise, 65 per cent of respondents said IT is responsible for managing marketing technology or services, compared to 30 per cent who listed marketers as the lead.

But perhaps, one of the biggest hurdles any couple has to overcome is learning how to balance a budget together. According to McLellan, marketing budgets were expected to grow by 6 per cent in 2013 and 10.4% of the average share of revenue is spent on marketing, compared to just 3 to 6% for internal IT. So, where is all this marketing budget going? According to the presentation, the dollars are being dedicated to more digital forms of marketing. For instance, 12.5% of respondents said their 2012 marketing budget went to digital or online advertising, 11.6% claim it went to content creation and management, and 10.7% cited search marketing. But IT is getting a small piece of the pie. While 64% of respondents said their company's marketing function has its own capital budget, respondents also noted that 14% of their company's marketing capital budget is owned by internal IT.

If relationships are all about give and take, some marketing and IT roles are beginning to fuse. For example, 70per cent of enterprise companies have hired a chief marketing technologist. And although 80% of these hybrid roles reside in the marketing department, nearly two thirds of them have an IT background. Almost all of them are being hired from outside their organizations, McLellan said.

So, what will it take to get marketing and IT to live happily ever after? McLellan said that “marketing and IT need to focus more on what they have in common than on their differences.” According to McLellan, both teams love new technology, think big, deliver results without the budgets they should have, and believe in the future of digital.
