The total worldwide market is assessed. A range of forecast assumptions are factored in. This study does not contain vendor-specific revenue, market shares, or vendor profiles."Talent shortage coupled with the high interest in adoption of new technologies will continue to drive high growth in business analytics services spending at the worldwide level. In addition, the desire to consume the entire life cycle of business analytics services will drive high spending growth across all business analytics services lines in the near future," said Ali Zaidi, senior research analyst, IT Consulting and Systems Integration Services. "As more business data gets consolidated and is made available to executives, outsourced big data and analytics services will continue to get embedded and pervade deeper into the enterprise. As these services become a key component in ensuring the agility and effectiveness of an enterprise's business processes and vendors are able to provide a diverse range of industry-specific use cases and assist customers in preparing a business case, customer adoption will increase. Vendors will also focus on acquiring or partnering with technology firms that provide unique big data or analytics IP to create differentiated offerings and create additional capabilities including highly skilled talent that will enable them to offer services across the value chain," said Mukesh Dialani, research director, Worldwide BPO and Engineering Services.
