    Given the impact of IT, many companies are starting

    to think differently about their IT investments and

    strategies. Rather than grudgingly viewing IT as a

    set of tools necessary for doing business and

    sometimes as an expensive and cumbersome set of

    tools many companies are looking instead to gain

    value from their IT investments. They are focusing

    on reengineering and optimizing their support

    processes and on driving IT to enable their

    businesses and improve their operations as well as

    their bottom lines.

    A recently completed ASUG/SAP Best Practices

    study (see sidebar for study details) shows thatcenters of excellence (COEs) are the primary vehicle

    for delivering industry-led project and program

    excellence. Centers of excellence provide a

    standardized approach across an entire organization,

    with strategies and templates designed to facilitate

    and enhance project management processes and

    approaches. Staffed with knowledgeable business

    and IT teams, these centers are company resources

    for current practices, technologies, and emerging

    trends, and they are designed to enable joint IT and

    business solutions with greater value, consistency,and efficiency.

    The study identified three main factors that inspire

    companies to institute centers of excellence: the

    desire to manage and lower total cost of ownership

    (TCO), the need to increase the value of their IT

    investments, and a drive to focus on customer

    satisfaction.

    The study also found that among well-integrated,

    mature COEs, certain best practices winning

    strategies, approaches, and processes that produce

    superior performance in an organization correlate

    with success. The best-performing companies

    minimize TCO by optimizing their COEs,

    centralizing the organization, standardizing ITsystems across the enterprise, managing

    performance, and focusing on customers. Finally,

    the study found that cooperation between business

    operations and IT is crucial to the successful

    implementation and operation of COEs.

    EXECUTIVE AGENDA

    6/20

    A centers of excellence (COE) best practices

    survey conducted by SAP and the Americas

    SAP Users Group (ASUG) from March to April

    of 2006 covered a wide sampling of businesses

    across several disparate industries. Fifty-nine

    companies took part in the study and came from

    a broad range of industries, including retail and

    wholesale, public sector, manufacturing,

    banking, and health care. Participants spanned

    the globe, with operations in Asia, Africa, the

    Middle East, Europe, South America, the United

    States, and Canada.

    Businesses also varied in size as measured in

    terms of the number of full-time equivalent (FTE)

    employees dedicated to their centers of

    excellence. The smallest, representing 25% of

    those surveyed, had from 1 to 10 FTEs, and the

    largest, 8% of the companies surveyed, had

    more than 150 FTEs. The number of years of

    operation of the COE was surveyed as well: 44%

    of companies had COEs in operation for less

    than 1 year; 15% for 1 to 2 years, 12% for 3 to 4

    years, 15% for 5 to 6 years, 6% for 7 to 8 years,

    and 8% for more than 8 years.

    Survey respondents were given scores based on

    responses to questions about their individual

    level of best practices adoption in five key areas:

    total cost of ownership, organizational level,

    systems standardization, performance

    management, and customer focus. Companies

    were then assigned a level from one to five,corresponding with the maturity level of their

    COE best practices adoption score: level one,

    marginal; level two, implementing and refining;

    level three, repeating performance; level four,

    excellent and quantifiable performance; and level

    five, optimal performance.

    ASUG/SAP CENTERS OF EXCELLENCE SURVEY

  • 8/6/2019 Centers of Excellence Optimize Your Business and IT Value

    7/20

    In looking in detail at centers of excellence, our

    recent ASUG/SAP Best Practices study found it is of

    paramount importance for successful centers of

    excellence (COEs) to ensure that business

    operations and IT are fully aligned and in synch.

    Such cooperation harmonizes business processes

    and corporate strategy with IT investments and

    strategy, maximizing effectiveness, success, and

    efficiency. This theme occurs again and again

    throughout the study results and has a profound

    impact on all aspects of COE operations.

    Indeed, its crucial to directly involve business

    operations in the design and scope of a center of

    excellence. After all, the business is and should be

    the main beneficiary of the work performed,

    enabled, and enhanced by a COE. The study clearly

    demonstrates the need for a balanced perspective

    between the overall business organization and IT in

    developing the center. And finally, a strong business

    focus is key to meeting and exceeding customer

    expectations.

    FACTORS DRIVING COE IMPLEMENTATION

    The best practices study found that three crucial

    needs initially drive companies to implement

    centers of excellence:

    Managing and lowering total cost of ownership

    (TCO)

    Enhancing value

    Focusing on customer satisfaction

    Moving beyond these three initial needs, key

    objectives of COEs include enhancing IT investment

    value, improving governance, managing change,

    improving support, and managing and loweringTCO.

    The study revealed that as centers of excellence

    become more mature, more accepted, and fully

    integrated into the operational fabric of the

    organization, these initial drivers evolve and become

    part of the core of its operation. As we will see in

    more detail later, this leads to the development of

    the right skills and talents to support the needs of

    the business in a cost-effective and efficient manner.

    Maturity

    Levels of

    Centers of

    Excellence

    The study shows that a number of factors influence

    the success of centers of excellence. The COE

    organization model, the IT system landscape,

    performance management processes and strategies,

    and sharpness of customer focus all contribute to

    the success or failure of a COE.

    In addition to these factors, study findings indicate

    that companies with more mature COEs achieve

    higher levels of value by implementing best

    practices.

    LEVELS OF COE MATURITY

    The survey assessed the maturity of participants

    COEs, ranking each into one of five levels, as shown

    in Figure 2.

    The study paints a picture of organizations by the

    level of maturity their COEs have reached.

    In the marginal or initial stage, level one, companies

    identify business processes and establish a COE

    organizational structure. IT generally uses a whats

    available instead of a whats best approach to

    systems implementation. Companies identify

    business processes, but they do not generally

    standardize or establish business processes across the

    organization, and they perform work on an ad hoc

    basis. Companies define process ownership only

    minimally, and they do not share documentation.

    They fail to establish performance measurement

    practices, and they do not define key performance

    indicators (KPIs). Project teams often follow

    informal practices, measuring only the basics, such

    as costs and schedules. Level one companies do not

    establish a customer focus as a primary driver, track

    and report on customer satisfaction, or report on

    performance management. Leadership is usually

    aware only of key milestones. Finally, these

    companies communicate with customers

    informally and in an unstructured way, and they

    lack clearly defined issue resolution practices.

    As COEs develop and mature (levels two and three),

    they make improvements across the board. TheCOE organization tends to centralize. IT systems

    evolve, instituting more definition and planning of

    functional and technical work. Business processes

    become standardized and documented, and process

    ownership is held by both the business units and the

    COE.

    At the highest levels of maturity (levels four and

    five), study findings showed companies reporting

    excellent COE performance. Organizations follow

    resource management plans. IT has centralized andstandardized systems. Business processes are

    standardized with the enterprise, shared,

    documented, and measured. A dedicated

    performance team ensures that the company reaps

    the expected value. Formal performance

    management practices, training, and

    COE MATURITY MATTERS

    communications are in place, and KPIs are refined,

    targeted, managed, monitored, and analyzed. A

    clear user governance structure is in place, and a

    transformation in thinking means that users are

    treated like partners. Most important, major

    changes are implemented through the lessons

    learned throughout the development and

    deployment of the COE.

    As COEs become more mature and optimize the

    adoption of best practices, making them core to

    COE operations, companies discover a need to

    develop talent to sustain the changing needs of the

    business in the most cost-effective manner. By thetime a company has reached level five, it has fully

    adopted and internalized a center of excellence

    culture that helps optimize the IT systems, overall

    organizational performance, and customer

    satisfaction.

    GREATER COE MATURITY =

    INCREASED BEST PRACTICES

    ADOPTION

    Nearly 36% of the companies in the survey

    demonstrated a high level of maturity in their

    COEs. These companies have adopted best practices

    that improve acceptance of IT systems across the

    organization, shorten project times, control project

    costs, improve strategic management decision

    making, and increase return on investment.

    According to the study, companies that have

    adopted the most COE best practices have COEs that

    are:

    Centralized, either with or without satellite

    offices, a clear key contributor to a lower TCO

    Implemented during the initial adoption and

    installation of their SAP solution

    Organized to include a key user program in

    which lines of business employees take the lead

    on facilitating the COE in their departments

    Aligned with a high level of standardization bothwithin business units and across the entire

    enterprise

    Less likely to permit undue customization of

    systems

    Focused on the customer and adhering to the

    overall corporate mission and strategy

    Companies ranked by the survey at the highest level

    of maturity earned many key and valuable results.

    With a mature and fully integrated COE, a company

    can realize a higher level of acceptance of its ITsystem, faster project completion, controlled

    project costs, and improved strategic management

    decision making all benefits that contribute to an

    improvement in ROI.

    Tellingly, study findings showed that 62% of level

    four and five companies incorporate continuous

    improvement practices and programs into their

    business approach, whereas for 72%, COEs drive a

    strong alignment between the business and IT and

    ensure equal participation with the business.

    11/20

    The study found five key actions in which the

    adoption of best practices has been shown to enable

    companies to optimize processes, meet their

    business needs and improve their bottom lines.

    These five actions are:

    Minimize TCO with an optimized COE

    Centralize the organization

    Standardize IT systems across the enterprise

    Manage performance

    Focus on the customer

    MINIMIZE TCO WITH AN OPTIMIZED

    COE

    The study identified a number of key benefits

    realized by adopting COE best practices. The first

    benefit is a reduced TCO the cost of

    implementation, execution, and maintenance

    directly due to the enablement of centers of

    excellence.

    Optimal COE performers, the survey found,

    significantly reduce TCO by centralizing to a highdegree; standardizing system landscapes and

    business processes; minimizing software

    installations; and following a strategy of managed,

    limited systems customization.

    Make no mistake: managing TCO is important. But

    lowering TCO at the expense of the other four

    actions would clearly be shortsighted. The

    companies surveyed all recognize that COEs are

    instrumental in improving the return on IT

    investments. The study also found that SAP-certifiedCOEs perform better than noncertified COEs.

    Successful centers are found in companies that

    implement strong lessons-learned approaches and

    that have a well-documented knowledge

    management process in place. Returning to an

    essential point, centers of excellence were shown

    not to be successful in companies without an equal,

    well-established partnership between the CIO and

    the business organization.

    However, even when a companys IT plan makes

    sound strategic and tactical sense, with a clear and

    compelling business case for the investment, several

    key barriers to achieving optimal value from an IT

    outlay still exist. Our survey revealed typical barriers

    whose effects can be ameliorated with an optimized

    COE:

    Unclear program value imperatives

    Executive disconnects on key business case

    assumptions

    Lack of value readiness due to entrenched

    organizational culture and technological factors,

    such as legacy systems

    Lack of program metrics keeping the focus on

    budget and deadlines

    Lack of ongoing value reviews to ensure that new

    IT capabilities deliver measurable value

    These barriers can lead to prohibitive costs and lost

    time due to IT changes, and they are a direct resultof a lack of alignment between business and IT

    strategies. Quick fixes then result in higher long-

    term costs and decreased functionality, with more

    and more of the budget up to 80% according to

    our survey spent on simply maintaining the

    technological status quo. This leaves a company

    caught in a spiral of spending without achieving the

    results and return on investment it needs.

    The lack of an effective COE organization and

    processes leads to a failure to achieve businessresults, excessive TCO, and delayed realization of

    the value of IT investments. The study indicated

    that COEs enabled companies to reduce the TCO of

    their system applications. Indeed, survey

    participants achieved significant reductions, as

    shown in Figure 3.

    KEY APPROACHES TO COE BEST PRACTICES

    Total cost of ownership is one of the most difficult

    metrics to benchmark. Even when using the most

    common metrics cost per user, full-time support

    employees per 100 users companies often dont

    obtain adequate results, or the results of their

    analyses are misleading. For example, consider the

    often-used TCO metric of lowest cost per user. Well-

    designed IT solutions often decrease the number of

    users needed to support business processes. But this

    highly favorable outcome typically creates a higher

    cost per user. The same is true of the converse. If a

    company has too many users, perhaps because of

    poor process structures or training, it achieves a low

    cost per user but this low value is misleading

    because it is due to undesirable factors. This does

    not imply that per-user metrics lack value; it merely

    suggests that companies require multiple metrics to

    make valid, balanced business decisions.

    The survey identified specific best practices crucial

    to clearing these barriers to reducing total cost of

    ownership:

    Certification of the center and equal partnership

    between the business organization and the COEregarding daily operations

    The institution of value checkups that ensure

    value is being achieved and that lessons learned

    are being adopted and incorporated

    Strong continuous improvement practices

    Strong alignment between business and IT and an

    equal partnership in the business

    CENTRALIZE THE ORGANIZATION

    Organizations with centralized COEs, the survey

    found, have better consistency and coordination,

    leading directly to less duplication of effort. These

    organizations configure and develop their IT

    systems by process or functional area instead of by

    business unit, leading to more efficient, more

    streamlined systems operations. The survey results

    are clear on this subject: 87% of all respondents

    COEs are centralized, and this percentage climbs to91% for the best-performing companies. A higher

    percentage of these mature companies address the

    full solution life cycle in the scope of their COEs.

    Furthermore, 46% of COEs address the full solution

    cycle, from business case development to

    continuous improvement and support.

    These best-in-class COEs evaluate the impact of

    changes on all areas of the business and efficiently

    allocate support services across their areas of

    responsibility. Organizations that have aligned

    resources with either new projects or support

    initiatives are more likely to contribute directly to

    lower staff turnover, ensuring that they retain talent

    and mitigate the risk of knowledge loss.

    This concept, understandably, applies to system

    upgrades as well. Over 70% of companies that

    reported late or over-budget projects did not have a

    COE in place. Simply put, COEs help ensure on-

    budget, on-time upgrades by facilitating the clear

    definition of an upgrade plan and path.

    The survey highlighted the importance of several

    best practices regarding systems standardization:

    Align noncore business with best practices to

    minimize customization

    Manage road maps and strategies, making sure

    they are in place and updated periodically

    Standardize system setup, applying it across the

    enterprise to the greatest extent possible

    Minimize the use of third-party applications

    Implement and follow system upgrade plans

    MANAGE PERFORMANCE

    Where performance management is concerned, thestudy found top performers consistently track

    operating costs and COE investments according to

    plan. This must be accompanied by consistent and

    frequent reporting so that companies can take

    corrective actions to avoid overruns.

    The survey reported that 37% of respondents have a

    formal process in place to measure COE

    performance and that most reviews are conducted

    quarterly or twice yearly. Top-performing

    companies demonstrated a clear advantage here,

    with 58% of level four and five companies reporting

    that they have a formal performance management

    plan in place.

    It is also important to be selective and keep a sharp

    focus in performance measurements measuring

    too many metrics can be counterproductive. One

    third of companies in the survey said that they

    measure four to six KPIs per project.

    FOCUS ON THE CUSTOMER

    Both COEs and the IT group must keep their focusever on the bottom line. This essentially means that

    a project must achieve high customer satisfaction

    ratings to be deemed successful.

    The survey findings showed a seemingly obvious

    correlation, but one that is important and

    sometimes missed: frequent communications with

    customers contribute to improved customer

    satisfaction levels.

    The ability to track and report on customer

    satisfaction is also a contributor to ensuring thatfeedback is made available to the COE and that

    corrective actions can be taken in an appropriate

    and timely manner. Most companies reported a very

    high level of customer focus, but, perhaps

    surprisingly, only 54% of companies surveyed

    explicitly report on customer satisfaction. Even

    among those that do report explicitly, very few

    involve customers in the review and feedback

    communication cycles.

    We found that while 83% of companies reported

    that their COE meets or exceeds their customer

    focus requirements, COEs are not generally well

    connected with business customers. Limited

    business involvement at all levels leads to lower

    customer satisfaction. Only a third indicated

    business involvement in the steering committee,

    and bimonthly stakeholder participation is even

    more limited at only 17%.

    The survey identified a number of customer focus

    best practices adopted by top-performing COEs. Top

    performers:

    Achieve high customer satisfaction by ensuring

    active business involvement with the core team,

    steering committee, and stakeholders

    Establish a user governance structure

    Use SLAs to facilitate communication with

    customers

    Your company can derive many direct benefits from implementing a certified center of excellence,including the following: Providing a proven approach for the effective implementation, maintenance, and improvement of

    business solutions A familiar and clearly defined starting point for business users, providing assistance with application

    and support issues and supplying up-to-date product and business process information Management and easy availability of experience and expertise to every corporate unit in equal

    measure Fast adoption of the business solution to meet changed market requirements or internal changes Roll out of best business processes in the corporate units Increased COE competence and expertise through training and experience Close, individualized end-user support through the in-depth knowledge of COE staff about customer-

    specific situations and the position within the group Clear definitions of measurable expectations that are then communicated and monitored to ensure

    consistency in standards of quality and customer focus

    The Benefits of a Certified COE

    CONCLUSION: KEY BEST PRACTICES

    The ASUG/SAP survey made three overriding

    factors abundantly clear. First, companies with more

    mature COEs can keep their eyes constantly on the

    prize of managing customer satisfaction without

    losing focus on TCO. Second, COE models that are

    formed in a spirit and atmosphere of collaboration

    and cooperation, aligning business and IT, can

    better address issues of continuous improvement,

    leading to an effective COE with optimized

    operation. And third, companies that deploy centers

    of excellence realize a lower TCO of their enterprise

    IT system.

    OVERALL KEY BEST PRACTICES

    Several critical best practices emerged among the

    highest ranked companies (level five). The

    performance drivers that have the highest impact

    on COE value achievement are the following:

    Centers of excellence affect on-target, on-value

    performance when they manage all processes and

    functions from problem definition to resolution

    including support-level functions and roles,

    escalation procedures, corrections, interface

    handling and error correction procedures, help

    desk training, performance metrics definition and

    problem analysis, road map strategy, and design.

    A documented knowledge management process

    drives on-time and on-budget performance and

    needs to include knowledge repository build,

    documentation requirements for support and

    knowledge packaging, training and help desk

    routing, and resolution certification.

    A centralized COE design drives effective delivery.

    This centralized structure is a key contributor to

    lower TCO.

    Limiting the amount of customization

    contributes to a faster time to market because it

    simplifies and shortens the testing and

    implementation phases.

    Centers of excellence are most effective when

    enacted during the initial system implementation

    phase.

    Business-owner involvement in decision making

    drives on-time, on-budget performance. All

    optimal COEs have adopted a business process

    owner model.

    Formal power user programs significantly

    influence programs achieving their expectedgoals and value. All organizations with optimally

    performing COEs have a power user program in

    place. Staffed by the business unit outside of the

    COE, power users provide the first line of support

    to the business user community.
