2 Introduction Research Objectives Research Report: Remote Office/Branch Office Technology Trends In order to determine the IT priorities and challenges currently faced by remote office/branch office (ROBO) locations, and how organizations plan to address those challenges, ESG recently surveyed 454 North American senior IT professionals representing midmarket (100 to 999 employees) and enterprise-class (1,000 employees or more) organizations. All respondents worked at headquarters locations or other centralized corporate sites and were responsible for ROBO IT operations and/or strategy, including the delivery of IT services to these locations, authorization of expenditures, or establishment and enforcement of corporate IT policies for remote/branch offices. Respondent organizations were required to have at least two ROBO locations to qualify for the survey. The survey was designed to answer the following questions: How many ROBO locations do organizations currently support? What is the average number of employees that work at each ROBO location? What is the largest ROBO in terms of number of employees? What percentage of ROBO locations has dedicated on-site IT staff? How do organizations determine which locations qualify for on-site resources? What percentage of an organization s total IT budget is dedicated to supporting ROBOs? What are the top ROBO IT priorities? What are the top networking and security challenges when it comes to supporting the IT needs of remote/branch offices? How are the majority of corporate applications and/or IT services delivered to users at ROBO locations? What benefits do organizations derive from delivering corporate applications and/or IT services to its ROBO locations? What challenges do organizations face in delivering corporate applications and/or IT services to its ROBO locations? What steps have they taken to address these challenges? How many servers do organizations have deployed at a typical ROBO location? How does this vary by the average number of employees per ROBO? How extensive is server virtualization usage at ROBO locations? What benefits has the technology yielded? On average, approximately how much data storage capacity is deployed at the typical ROBO location? How does this vary by the server count or number of employees at the typical ROBO location? What type of external disk storage system is the most widely used at ROBO locations? How does this vary by average ROBO storage capacity levels? What is the primary data protection process organizations deploy at their ROBO locations? For those organizations performing on-site backup operations at ROBOs, is disk or tape the preferred storage media? Who is typically responsible for backup operations and media management at these locations? Do these organizations have any plans to centralize their backup processes? If yes, why? For those organizations backing up their data to a central location, what drove them to this model and what challenges if any have they experienced? Survey participants represented a wide range of industries including manufacturing, financial services, communications and media, health care, retail, government, and business services. For more details, please see the Research Methodology and Respondent Demographics sections of this report.

3 Research Methodology To gather data for this report, ESG conducted a comprehensive online survey of IT managers from private- and public-sector organizations in North America (United States and Canada) between April 19, 2011 and May 2, To qualify for this survey, respondents were required to be senior IT managers working at headquarters locations or other centralized corporate sites and personally responsible for or familiar with the IT operations and strategies at their organization s remote/branch offices. All respondents were provided an incentive to complete the survey in the form of cash awards and/or cash equivalents. After filtering out unqualified respondents, removing duplicate responses, and screening the remaining completed responses (on a number of criteria) for data integrity, we were left with a final total sample of 454 IT managers. Please see the Respondent Demographics section of this report for more information on these respondents. Note: Totals in figures and tables throughout this report may not add up to 100% due to rounding.

4 Respondent Demographics The data presented in this report is based on a survey of 454 qualified respondents. The figures below detail the demographics of the respondent base, including organizations total number of employees, primary industry, and annual revenue. Respondents by Number of Employees The number of employees in respondents organizations is shown in Figure 1. Figure 1. Survey Respondents, by Number of Employees How many total employees does your organization have worldwide? (Percent of respondents, N=454) 20,000 or more, 22% 100 to 249, 12% 250 to 499, 9% 500 to 999, 9% 5,000 to 19,999, 18% 2,500 to 4,999, 13% 1,000 to 2,499, 18% Source: Enterprise Strategy Group, Respondents by Annual Revenue Respondent organizations annual revenue is shown in Figure 2.

5 Respondents by Industry Research Report: Remote Office/Branch Office Technology Trends Respondents were asked to identify their organization s primary industry. In total, ESG received completed, qualified respondents from individuals in 19 distinct vertical industries, plus an Other category. Respondents were then grouped into the broader categories shown in Figure 3. Figure 3. Survey Respondents, by Industry What is your organization s primary industry? (Percent of respondents, N=454) Other, 19% Manufacturing, 22% Retail/Wholesale, 7% Business Services (accounting, consulting, legal, etc.), 7% Communications & Media, 9% Health Care, 9% Government (federal/national, state/province/county /municipal/other local government), 10% Financial (banking, securities, insurance), 16% Source: Enterprise Strategy Group, Respondents by Area of Technology Responsibility Respondents current area of technology responsibility is shown in Figure 4.
