Description

FIELD OF THE INVENTION

This invention relates generally to service oriented architecture (SOA) shared service lifecycle management and more specifically to the identification of SOA shared service opportunities.

BACKGROUND OF THE INVENTION

In the past, software architectures have attempted to deal with increasing levels of software complexity. As the level of complexity continues to increase, traditional architectures are reaching the limit of their ability to deal with various problems. At the same time, traditional needs of information technology (IT) organizations persist. IT organizations need to respond quickly to new requirements of the business, while continuing to reduce the cost of IT to the business by absorbing and integrating new business partners, new business sets, etc.

Deconstructing and understanding business architectures to successfully deliver enterprise services is a complex undertaking for all businesses. Many prior art approaches delay identification of business opportunities for service orientations, which has a negative impact on project delivery and budget. Further, the longer the delay in identification of business opportunities for service orientation, the more difficult it becomes to change the course of portfolio planning activities.

SUMMARY OF THE INVENTION

In one embodiment, there is a method for identifying a service oriented architecture (SOA) shared service opportunity. In this embodiment, the method comprises: identifying a plurality of projects from each of a plurality of lines of business; selecting a set of projects common to more than one line of business from the plurality of lines of business; and evaluating the set of projects common to more than one line of business from the plurality of lines of business to identify a SOA shared service opportunity.

In a second embodiment, there is a system for identifying a service oriented architecture (SOA) shared service opportunity. In this embodiment, the system comprises at least one processing unit, and memory operably associated with the at least one processing unit. An opportunity tool is storable in memory and executable by the at least one processing unit. The opportunity tool comprises: an identification component configured to identify a plurality of projects from each of a plurality of lines of business; a selection component configured to select a set of projects common to more than one line of business from the plurality of lines of business; and an evaluation component configured to evaluate the set of projects common to more than one line of business from the plurality of lines of business to identify a SOA shared service opportunity.

In a third embodiment, there is a computer-readable medium storing computer instructions, which when executed, enables a computer system to identify a service oriented architecture (SOA) shared service opportunity, the computer instructions comprising: identifying a plurality of projects from each of a plurality of lines of business; selecting a set of projects common to more than one line of business from the plurality of lines of business; and evaluating the set of projects common to more than one line of business from the plurality of lines of business to identify a SOA shared service opportunity.

In a fourth embodiment, there is a method for deploying an opportunity tool for use in a computer system that identifies a service oriented architecture (SOA) shared service opportunity.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of this invention are directed to identifying a service oriented architecture (SOA) shared service opportunity. In these embodiments, an opportunity tool provides this capability. Specifically, the opportunity tool comprises an identification component configured to identify a plurality of projects from each of a plurality of lines of business; a selection component configured to select a set of projects common to more than one line of business from the plurality of lines of business; and an evaluation component configured to evaluate the set of projects common to more than one line of business from the plurality of lines of business to identify a SOA shared service opportunity.

FIG. 1 illustrates a computerized implementation 100 of the present invention. As depicted, implementation 100 includes computer system 104 deployed within a computer infrastructure 102. This is intended to demonstrate, among other things, that the present invention could be implemented within a network environment (e.g., the Internet, a wide area network (WAN), a local area network (LAN), a virtual private network (VPN), etc.), or on a stand-alone computer system. In the case of the former, communication throughout the network can occur via any combination of various types of communications links. For example, the communication links can comprise addressable connections that may utilize any combination of wired and/or wireless transmission methods. Where communications occur via the Internet, connectivity could be provided by conventional TCP/IP sockets-based protocol, and an Internet service provider could be used to establish connectivity to the Internet. Still yet, computer infrastructure 102 is intended to demonstrate that some or all of the components of implementation 100 could be deployed, managed, serviced, etc., by a service provider who offers to implement, deploy, and/or perform the functions of the present invention for others.

Computer system 104 is intended to represent any type of computer system that may be implemented in deploying/realizing the teachings recited herein. In this particular example, computer system 104 represents an illustrative system for identifying a SOA shared service opportunity. It should be understood that any other computers implemented under the present invention may have different components/software, but will perform similar functions. As shown, computer system 104 includes a processing unit 106, memory 108 for storing an opportunity tool 153, a bus 110, and device interfaces 112.

Processing unit 106 collects and routes signals representing outputs from external devices 115 (e.g., a keyboard, a pointing device, a display, a graphical user interface, etc.) to opportunity tool 153. The signals can be transmitted over a LAN and/or a WAN (e.g., T1, T3, 56 kb, X.25), broadband connections (ISDN, Frame Relay, ATM), wireless links (802.11, Bluetooth, etc.), and so on. In some embodiments, the signals may be encrypted using, for example, trusted key-pair encryption. Different external devices may transmit information using different communication pathways, such as Ethernet or wireless networks, direct serial or parallel connections, USB, Firewire®, Bluetooth®, or other proprietary interfaces. (Firewire is a registered trademark of Apple Computer, Inc. Bluetooth is a registered trademark of Bluetooth Special Interest Group (SIG)).

In general, processing unit 106 executes computer program code, such as program code for operating opportunity tool 153, which is stored in memory 108 and/or storage system 116. While executing computer program code, processing unit 106 can read and/or write data to/from memory 108, storage system 116, and a SOA shared services registry 117. SOA shared services registry 117 stores a plurality of potential SOA shared services and associated metadata, as well as rules against which the metadata is compared to locate, update, and store SOA shared services from decomposed business architectures, as will be further described below. Storage system 116 may also comprise a plurality of projects (e.g., business initiatives, goals, plans, etc.) from each of a plurality of lines of business of an enterprise 120. Storage system 116 and services registry 117 can include VCRs, DVRs, RAID arrays, USB hard drives, optical disk recorders, flash storage devices, or any other similar storage device. Although not shown, computer system 104 could also include I/O interfaces that communicate with one or more external devices 115 that enable a user to interact with computer system 104.

Implementation 100 and opportunity tool 153 operate within a broader SOA shared services and lifecycle management process (not shown), which identifies, evaluates, implements, and manages SOA shared services. SOA SSLMP provides guidance for decomposing a business architecture of an enterprise and managing the entire lifecycle of a shared service(s) within the enterprise. Specifically, SOA shared services and lifecycle management process (SSLMP) includes new and distinct roles, governance checkpoints, increased collaboration requirements, and new decision control points. SOA SSLMP takes an extended view in identifying the various touch-points inside and outside of the organization to plan, build and manage shared services within a SOA shared services portfolio. SOA SSLMP defines a framework for shared services governance and lifecycle management that provides a formal approach and structure to enable the decomposition of business architectures to define, design, implement and manage an enterprise services portfolio. This framework allows enterprises to define or leverage existing processes and methodologies to decompose business architectures to deliver a comprehensive portfolio of enterprise services.

Referring now to FIG. 2, a more detailed view of opportunity tool 153, which identifies SOA shared service opportunities (i.e., components/areas with the potential for re-use within the enterprise to minimize duplication of resources) will be provided. As shown, opportunity tool 153 comprises an identification component 155 configured to identify a plurality of projects 136 from each of a plurality of lines of business (LOB) 132 (e.g., a business component, unit, or group within enterprise 120). Typically, as part of an annual planning process within enterprise 120, each LOB 132 identifies the various business projects they plan to undertake for the year. The LOBs 132 prioritize the projects in terms of impact, resources, budget, etc., and conduct a high-level business case for each project. It is typical that each of plurality of LOB 132 will have overlapping projects common to multiple LOBs, which are then discussed and analyzed at larger meetings held within enterprise 120.

In an exemplary embodiment, opportunity tool 153 comprises a selection component 160 configured to select a set of projects 140 common to more than one LOB from plurality of lines of business 132. To assist with this, as shown in FIG. 2, a SOA governance unit 122 provides input to identify plurality of projects 136 from each of plurality of lines of business 132 and to select set of projects 140 common to more than one LOB from plurality of LOB 132. In the present invention, SOA governance unit 122 works with each LOB 132 during the planning phase to identify the impact of each business project from a SOA/IT perspective. It will be appreciated that SOA governance unit 122 described herein may represent a committee or group of individuals within an organization, or may represent a module, segment, or portion of code, which comprises one or more executable instructions for evaluating and managing the SOA shared service.

In one embodiment, SOA governance unit 122 may create a questionnaire having qualification criteria to help prioritize projects within each LOB. Each project may be prioritized using a weighted technique to show the initial priority of each project, and a metric 172 may be created, as shown in FIG. 3. Metric 172 quantifies the project in terms of business, technology and application, in this case, on a scale of 1-10, with 10 indicating full compliance with the business objectives of the LOB. Based on metric 172, SOA governance unit 122 evaluates each of plurality of projects 136 to prioritize set of business projects 140 common to more than one LOB from plurality of lines of business 132. From this, an evaluation component 165 (FIG. 2) evaluates set of projects 140 common to more than one LOB from plurality of LOB 132 to identify a SOA shared service opportunity 145. For example, as shown in FIG. 3, each project may be rated to get an overview of the strength of the project offering in terms of SOA. In this case, metric 172 has a strong business and technology driver, but a significantly lower application score (i.e., strategic importance and leveraging of current assets). This may indicate that the project does not reduce redundancy or increase efficiency, and applications that involve the project may not be ready for SOA shared service integration.

Next, based on the evaluation, SOA governance unit 122 coordinates communication between each of plurality of LOB 132 to help prioritize projects and plan for integration. Specifically, SOA governance unit 122 coordinates meetings between each of plurality of LOB 132 and IT personnel capable of integrating SOA shared services. Typically, results from each of these meetings are input to more comprehensive meetings to evaluate projects on an enterprise-wide scale. The long-term strategies and initiatives are discussed for each of set of projects 140 common to more than one LOB to select projects that will be implemented by enterprise 120.

Next, as shown in FIG. 2, each LOB 132 prepares a high-level business case 148 for the selected projects. In one example, high-level business case 148 could be a document or presentation prepared by each LOB 132, which includes the background of the project, the expected business benefits, the options considered (with reasons for rejecting or carrying forward each option), the expected cost of the project, a gap analysis, and the expected risks. To accomplish this, evaluation component 165 is configured to prepare business case 148 for the SOA shared service opportunity, and prioritize set of projects 140 common to more than one line of business from plurality of lines of business 132 based on business case 148 for SOA shared service opportunity 145. SOA governance unit 122 is involved with these steps as well, assisting with business case 148, project prioritization, project funding, etc.

Referring now to FIG. 4, a SOA services lifecycle management process (SLMP) for identifying a SOA shared service opportunity will be described in further detail. As shown, at point 1, each LOB identifies and prioritizes business projects they will undertake for the year. At point 2, the business projects common to more than one LOB are identified. The SOA governance body assists with the identification of common projects, as shown at point 3. At point 4, the SOA governance body coordinates meetings between the LOBs and IT to identify common projects. At point 5, IT works with the LOBs and the SOA governance body during common project identification, including performing capability planning. SOA core team works with the LOBs to help prepare the business case for shared service opportunities, as shown at point 6. Next, at point 7 the business projects may be re-prioritized, along with the associated funding allocations. At point 8, IT works with the individual LOBs to fund, prioritize, and implement the SOA shared service projects.

It will be appreciated that the approach shown in of FIG. 4 represents one possible implementation of a process flow for identifying a SOA shared service opportunity. SOA SLMP flow illustrates the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each portion of the flowchart may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It will also be noted that each block of flowchart illustration can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.

Further, it can be appreciated that the methodologies disclosed herein can be used within a computer system to identify a SOA shared service, as shown in FIG. 1. In this case, opportunity tool 153 can be provided, and one or more systems for performing the processes described in the invention can be obtained and deployed to computer infrastructure 102. To this extent, the deployment can comprise one or more of (1) installing program code on a computing device, such as a computer system, from a computer-readable medium; (2) adding one or more computing devices to the infrastructure; and (3) incorporating and/or modifying one or more existing systems of the infrastructure to enable the infrastructure to perform the process actions of the invention.

The exemplary computer system 104 may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, people, components, logic, data structures, and so on that perform particular tasks or implements particular abstract data types. Exemplary computer system 104 may be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.

Furthermore, an implementation of exemplary computer system 104 may be stored on or transmitted across some form of computer readable media. Computer readable media can be any available media that can be accessed by a computer. By way of example, and not limitation, computer readable media may comprise “computer storage media” and “communications media.”

“Computer storage media” include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules, or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by a computer.

“Communication media” typically embodies computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as carrier wave or other transport mechanism. Communication media also includes any information delivery media.

The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared, and other wireless media. Combinations of any of the above are also included within the scope of computer readable media.

It is apparent that there has been provided with this invention an approach for identifying a SOA shared service opportunity. While the invention has been particularly shown and described in conjunction with a preferred embodiment thereof, it will be appreciated that variations and modifications will occur to those skilled in the art. Therefore, it is to be understood that the appended claims are intended to cover all such modifications and changes that fall within the true spirit of the invention.
