A common response is to hire a consultant and generate documentation to create better storage-related processes that fix capacity misallocations, improper storage configurations, lax change control and poor troubleshooting practices. But these efforts rarely address the root causes of process breakdowns.
Business-unit executives are increasingly favoring another approach and pressuring their IT departments to implement International Standards Organization (ISO)-compliant procedures and policies. These process frameworks are supposed to be applied across all departments within IT, so they're moving to the front burner for storage managers. Storage professionals need to know the trends in storage process improvement, the key frameworks and how to justify their implementation, and how to improve their chances of success during rollout.
Process improvement is a broad topic with a rich history. A series of process-oriented management trends (including reengineering, Total Quality Management, Theory of Constraints and Six Sigma) have typically addressed departments other than IT, such as sales or manufacturing. Process frameworks, however, are focused directly on IT departments.
The first step is to choose a framework. Most American firms turn to the U.K.-developed IT Infrastructure Library (ITIL). ITIL offers a superstructure of best practices, governing processes and documents in the form of "books." But such frameworks don't include all the necessary "piece parts" to implement standard processes--certainly not storage-related operational procedures--in a data center. Out-of-the-box implementations of ITIL simply don't exist.
Users need to take a framework and see its expression in a standard, of which there are several. Some, like BS15000 certification and Control Objectives for Information and related Technology (COBIT), encompass all the IT disciplines and try to capture the ITIL spectrum; others are more specific to a technology stack, such as the Microsoft Operations Framework (MOF) or the SEI Capability Maturity Model for software development. There are even storage-specific implementations, such as the Storage Management Lifecycle (SML), a proprietary approach offered by GlassHouse Technologies Inc., Framingham, MA.
Two ITIL books, Service Support and Service Delivery, from the Infrastructure Library Series published by Stationery Office, contain the processes of most interest to storage managers. Service Support describes an effective help-desk function and covers five processes that provide IT service stability and flexibility. Service Delivery encompasses five additional processes that help to deliver quality, cost-effective IT services. The distinction between the two may seem subtle, but the former focuses on internal IT activities while the latter focuses on how technology is provisioned to the user. These two books are grouped under the ITIL concept of Service Management. The spotlight on SLAs (a component of Service Management) has resulted in the creation of IT Service Management (ITSM), which has its own governing body (The IT Service Management Forum), certifications, coursework, media outlets, conferences and so on.
Lisa Huston is assistant vice president, network operations at Raymond James Financial Inc., a St. Petersburg, FL-based financial services company with 2,100 locations worldwide. "For our organization, the key challenges begin with changing the behavior of our storage administrators, as well as our customers, in regards to following new processes," she says. Formal processes are becoming much more important, she notes. "Prior to Sarbanes-Oxley, a phone call or an e-mail requesting action be taken would often suffice. Now, a more formal request process, complete with documentation, has become a requirement."
|Process, procedure and policy|
"We have good procedures, isn't that enough?" That's a frequent reaction of IT managers upon hearing about process frameworks. In the current environment of service-oriented infrastructure delivery, the answer is "No." Many storage departments don't understand the differences between process, procedure and policy. Accordingly, when they try to document their internal disciplines, they end up confusing the terms. The result is a jumble of documents that don't fit together well, don't establish common operating methods or offer the opportunity for continuous improvement.
The 10 ITIL Service Management processes, such as change management and configuration management, are generic and applicable to every IT department. ITIL advocates typically refer to Proctor & Gamble, which implemented an ITIL-based initiative that has purportedly saved the firm $500 million over four years. There's gold in the hills of operational process improvement; the trick is finding it.
Process improvement is realized in tangible and intangible benefits. CheckFree Corp.'s Electronic Commerce Division, an electronic billing and payment service, hasn't "quantified the exact cost savings associated with [storage process] formalization, as the benefits, particularly around provisioning, are fairly intuitive," says John Michelone, director of storage systems. But even when benefits are measurable (such as reducing cycle times or improving provisioning speed), they're often attributed to a technology implementation or claimed by other corporate initiatives. Any documented savings (that accrue only at the end of the project) have to be balanced against the internal resource and external consultancy costs necessary to conduct a successful implementation (which are incurred at the beginning of the project).
Some benefits of a successful ITIL implementation can be directly measured, such as a reduction in SLA penalties. Others involve cost avoidance, such as reducing outages due to human error and limiting the impact of loss of service on revenue. The bulk of tangible savings, however, come from one source: labor. This is because process improvement brings higher productivity to operational tasks, which may allow for reductions in support staff.
Organizations skittish about labor savings may prefer to focus on the intangible benefits, which are even greater, but not directly attributable to the bottom line. These include:
- Improved availability, reliability and security of mission-critical apps, yielding increased customer satisfaction.
- With IT better aligned with business, the risk of not meeting business requirements is reduced.
- Services provided in accordance with documented and auditable procedures.
- Better communication among IT staff and users through a common language.
- Information can now justify IT services and establish criteria for monitoring SLAs.
Overall, expected savings from ITIL-like process improvement projects may be difficult to document. Even so, these initiatives are proliferating as storage managers realize they need more standardization. "This [process improvement] is something that must be done," notes Huston at Raymond James. "We can't afford not to have formal procedures."
In addition to the challenges of cost-justification, process frameworks are hard to implement. One drawback to framework-oriented solutions is that they're based on a complete set of formal and interdependent processes. However, most organizations start from ground zero, typically having a patchwork of storage-related procedures, some of which are formal. It's important to understand that frameworks don't provide a "path" on how to move from an undocumented and processless environment to a smooth-running and disciplined shop.
But there are viable paths to a successful ITIL implementation. For many companies, a good place to begin is with an assessment that compares actual practices with best practices. The assessment can be done by a third party or even with the use of online tutorials. Executive buy-in is also critical; such support is needed to protect critical resources and provide momentum for lasting behavioral change.
Organizations that can provide help for those contemplating framework implementations include:
- American ITIL (www.americanitil.com)
- ITIL Survival (www.itilsurvival.com)
- ITSM Watch (www.itsmwatch.com)
- ITIL Portal (www.itilportal.com)
- IT Governance Institute (www.itgi.org)
Some advocates of process frameworks imply that if all the techniques/structures aren't adopted by the book, the effort won't be successful. But many organizations aren't comfortable with the rigor and formalism of ITIL, so they try to "bootstrap" their way into process improvement without fully adopting a formal framework. This approach can work provided the project plan is sound, success is well-defined and executive support is unswerving. No matter the approach used, implementations usually last for years. With an effort of such magnitude, organizational resistance, budget pressures and changing priorities can all conspire to hinder progress.
Here are 10 ways to improve your chances of successfully implementing process frameworks:
- Run the implementation as an organization change initiative, not an IT project. IT projects tend to be technology focused with limited goals, while this effort is more broad-based.
- Avoid the temptation to create the perfect process document on the first go-round. Because you'll be continuously measuring progress, start with the basics. Be practical and don't try to leap to a mature process.
- Count smaller wins along the way. Leverage micro-successes to help build and sustain momentum.
- Develop a complete service management book, not just one or two processes. Releasing processes incrementally is fine, as long as everyone knows that the end state is a set of interconnected processes.
- Focus on the complete portfolio of IT departments, not just on one IT group. It's OK to have the storage, server or database group serve as lead implementers, absorbing the lessons learned and acting as an internal corporate guinea pig. It's not advisable, however, to allow this group to remain isolated.
- Measure the rollout. The success of process improvement initiatives, like most projects, can and should be tracked. In its first year of implementation, CheckFree's program had 10 metrics. "I believe [last year] we were measuring 58 metrics," says the firm's Michelone, "all stated in terms of the customer's point of view."
- Avoid making the process document itself the goal. Writing a long and detailed document capturing every nuance of a process shouldn't be the objective; instead, define measurable attributes and design a process to exceed those metrics.
- Welcome external assistance. Consulting help is almost mandatory. It's difficult for IT organizations to retain staff skilled in organizational transformation, so it pays to hire a third party; consultants can serve as change agents.
- Dedicate the "right" internal resources. Staffers directly involved in the project need to have sufficient skill, passion and expertise to thrive in an organizational change role.
- Link the success of the effort with people's pay. Michelone says CheckFree "tied incentives and bonuses to internally set Sigma goals, which overcame any initial challenge there might have been in terms of getting everyone on the same page."
Like any major cross-functional initiative, a process framework implementation can get sidetracked and fall short of expectations. Storage managers can get caught too far out in front or lag too far behind such IT-wide efforts. A realistic approach is needed, one that focuses on the art of what's possible in the data center in establishing greater process discipline, particularly within storage operations.
One way to ensure that necessary improvements to operational governance are made visible to management is to incorporate them into an overall storage strategy. Such a strategy should define the what, when and why of process improvement.
Developing a storage strategy has become a necessity for some. A draft of Raymond James' first formal storage strategy document was published recently and was scheduled to be released during the summer. "In this document, we address governance by describing the state of our process documents, formal policies and procedures," says the firm's Huston. "We expect to develop and/or improve these in the coming year, and to continue to explain why these changes are necessary."
