The present invention generally relates to process analysis systems, and particularly to systems and methods for integrating financial models into workflow software.
In a business organization, Activity Based Costing (ABC) is a method of assigning the organization's resource costs through activities to the products and services provided to its customers. ABC is generally used as a tool for understanding product and customer cost and profitability. As such, ABC has predominately been used to support strategic decisions such as pricing, outsourcing, identification and measurement of process improvement initiatives.
ABC was developed as an approach to solve the problems of traditional cost management systems. These traditional costing systems are often unable to determine accurately the actual costs of production and related services. Consequently managers were making decisions based on inaccurate data especially where there are multiple products. Instead of using broad arbitrary percentages to allocate costs, ABC seeks to identify cause and effect relationships to objectively assign costs. Once costs of the activities have been identified, the cost of each activity is attributed to each product to the extent that the product uses the activity. ABC often identifies areas of high costs per unit and so directs attention to finding ways to reduce the costs or to charge more for costly products.
ABC is generally viewed as a desirable management tool to make informed decisions about business optimization, value of individual products, and the cost of servicing specific customers. However the collection of data and continual validation of the assumptions surrounding ABC can make the cost of ABC itself prohibitive.
Business Process Management (BPM) is an emerging field of knowledge and research at the intersection between management and information technology, encompassing methods, techniques and tools to design, enact, control and analyze operation business processes involving humans, organizations, applications, documents and other sources of information. BPM covers activities performed by organizations to manage and, if necessary, to improve their business processes. While such a goal is hardly new, software tools called business process management systems have made such activities faster and more cost effective. BPM systems monitor the execution of the business processes so that managers can analyze and change processes in response to data, rather than just a hunch.
In brief, BPM, or more simply, electronically enabled workflow, is used to model, automate, and optimize the flow of information and work in many key business processes. The activities analyzed in a typical workflow using BPM, such as the approval of a lending application, may be the same activities that are analyzed to perform ABC. However, BPM and ABC are usually performed independently. As a result there may be some duplication of effort when ABC and BPM are performed on the same subject matter. Further, because ABC and BPM are conducted separately, information and tools developed using BPM may not be available to the ABC process and information tools developed using ABC may not be available to the BPM process.
Another problem with ABC is the maintenance of the financial model when processes undergo process re-engineering. This is frequently a breaking point for ABC, as the assumptions underlying ABC must be revisited in detail when the process changes. Prevailing opinion has been that process re-engineering is costly and rarely performed, and that, once automated, business processes remain stable. However advances in BPM tools, including process simulation and analysis, have placed process re-engineering capabilities in the hands of the business users, resulting in far more frequent process changes.
Another consequence of the advances in BPM tools is that it has become far easier to design, deploy, and maintain a large number of automated business processes. Consequently, the number of activities that are automated and tracked is growing, and is no longer confined to a small number of the highest value business processes in an organization.
Accordingly, there is a need for systems and methods that improve on existing ABC and BPM systems and to reduce the duplication of effort when both techniques are employed on the same subject matter. Also, there is a need for ways in which information and tools gained from ABC may be utilized in BPM processes. In addition, there is a need for ways in which information and tools gained from BPM may be utilized in ABC processes. Further there is a need to provide a mechanism for maintaining the financial model in ABC when processes undergo routine or even large scale re-engineering.
To overcome the limitations in the prior art briefly described above, the present invention provides a method, computer program product, and system for integration of financial models into workflow software to enable Activity Based Costing (ABC).

Various advantages and features of novelty, which characterize the present invention, are pointed out with particularity in the claims annexed hereto and form a part hereof. However, for a better understanding of the invention and its advantages, reference should be made to the accompanying descriptive matter together with the corresponding drawings which form a further part hereof, in which there are described and illustrated specific examples in accordance with the present invention.
The present invention is described in conjunction with the appended drawings, where like reference numbers denote the same element throughout the set of drawings:
The present invention overcomes the problems associated with the prior art by teaching a system, computer program product, and method for integrating financial models into workflow software to enable Activity Based Costing (ABC). The invention involves the introduction of financial tools into a Business Process Management (BPM) system. As a result, the model of the workflow also models the cost drivers of the system. In addition, process analysis tools can be applied to generate ABC financial outputs. In the prior art, ABC and BPM were performed separately and resulted in some duplication of processes as information and tools from ABC were not available to BPM and information and tools from BPM were not available to ABC.
Workflows, such as BPM, include a number of steps and actions that are to be taken at each step. ABC also involves the reduction of a complex task or process into financially relevant steps such that the cost drivers for the process can be determined, and costs can be attributed to various products, groups, customers, and so on. In accordance with embodiments of the invention, by introducing a financial aspect to workflow modeling, steps in the workflow can be related to cost drivers. Cost drivers that do not relate to a step in the workflow can be modeled within the system as finance-only steps. These steps would perform no work, but would accumulate costing information for later analysis.
By using the teachings of the invention, steps that involve a person performing an action can be timed such that the labor hours of performing the step can be more accurately modeled, and variations in the labor hours (and thus cost) can be attributed accurately to the cause of that variation. For example, an analysis could be performed to determine which customers require the greatest number of labor hours of post-sales support. Costs associated with initiating support incidents with other agencies could also be tracked and attributed to the customer and product that drove that activity.
The financial model of work may operate in parallel and, in many cases, would simply follow the physical movement of the work item. Thus it would be a simple matter to maintain the financial model when processes undergo process re-engineering. This is frequently a breaking point for ABC, as the assumptions underlying ABC must be revisited in detail when the process changes. By modeling ABC within the workflow system in accordance with the invention, process changes would be immediately reflected in the costing reports.
Also, the present invention enables the user to define and maintain a global cost model, and to distribute those costs over a large number of deployed workflows. Another feature of the present invention is the ability to integrate cost and resource consumption data with the workflow, so that a business user who is modifying the workflow will automatically be updating the cost data as well. Furthermore, the invention provides the ability to roll up actual costs from a large number of workflows and review that at a global level. This could drive changes to the global cost model described above. Changes to the global cost model, such as the estimated cost of a given resource, would then automatically be reflected in the cost data accumulated for all workflows that consume that resource.
Referring now to
In more detail, in step 1, workflow design 12 and activity-based cost design 14 are performed. The workflow design and activity-based cost distributions may be designed independently. Alternatively, the two are built together in a single tool. That is, in some embodiments of the invention, workflow modeling tools also include cost modeling tools. Costs can be assigned to work steps based on fixed cost, calculated from data in the workflow, based on durations, and so on. Costs can also be allocated on the workflow map between steps where real costs are incurred but are not reflected in the workflow. For example, there might be storage costs for in-process materials between steps. The storage of material is not a work item that is modeled in the workflow, so a new idea has to be added to the workflow for modeling costs outside of the work directly performed. The result is a unified workflow and financial cost model 16, which may reflect a plurality of workflows and financial models.
In step 2, the unified workflow model and financial cost model 16 has been deployed to a functional application and is executed by a workflow execution module 18. Each execution accumulates a workflow audit trail as well as detailed cost information. This information, consisting of workflow audit data 20 and cost data 22, can be routed simultaneously to two types of monitoring/controlling tasks, which are usually performed by different groups in the enterprise or company. In particular, in step 3, the workflow audit data is used in workflow monitoring and controlling applications 24 and cost data is also fed to financial monitoring and controlling applications 26. First, the workflow tools are used to evaluate the performance of the workflow, to see if any adjustments are required or if the work is proceeding optimally. In one embodiment, these tools present statistics such as number of executions, number of times each step is performed, step durations, delays, and so on, as well as summary data gathered in the workflow (data items used for decision-making in the workflow).
Also, in some embodiments in step 3, the workflow monitoring and controlling applications can present not just number of executions, but also real cost data. This would allow the business process owner to make evaluations and adjust the workflow based on the real cost of the work. For example, a business process (BP) owner might see that a certain step is performed 2× more frequently than another, and take action to reduce the number of times the more frequent step is executed. However, if the BP owner saw cost information, it might be revealed that the cost of the first step is only 0.4× the cost of the second, per execution, and thus the second step actually costs 25% more. Cost data presented in the workflow monitoring tool makes analysis, simulation, and optimization of the workflow far more relevant to the company.
Additionally, if the unified workflow and financial model 16 includes resource behavior such as the ability of the company to usefully absorb surpluses, then the simulation and analysis tools will be able to provide better information about the possible impact of changes. For example, a proposed change to the workflow might reduce the need for a particular resource, but if the surplus resource cannot be utilized productively elsewhere or efficiently reduced, then there is no actual financial benefit to the change. In another example, a proposed change to a workflow might require slightly more of a particular resource. If that resource is already utilized at capacity, then the change cannot be implemented, or must be implemented with a higher cost (outsourcing, or the cost of ramping up that resource).
As shown in block 28 and in step 4, when analysis of workflows may result in changes 28 to that workflow that rearrange the use of existing resources, the financial model that is connected to the workflow can be adjusted automatically. That is, those changes 24 may simultaneously update the unified workflow and financial model 16, so cost data continues to flow uninterrupted and with high quality. This allows the sometimes frequent changes to a workflow in production to continuously reflect current cost data to the monitoring and controlling tools.
In this embodiment, there is a feedback loop of cost distribution. This allows the financial group in the company to monitor the cost outputs of the workflow systems and make global changes to the distribution of costs. The idea is that there are a great number of different workflows operating in the company, and each one contributes costs and consumes resources. In this embodiment, the system 10 should have a facility for rolling up and distributing down the various costs and resource constraints. From a global financial perspective, a model of costs, activities, and distributions can be built. This global financial model 11 can be used in the development of the individual workflow/financial models. The output of each workflow is a set of costs that can be rolled up and then compared with the global model 11. A financial analyst can review the data and make changes to the global financial model. This would then automatically be distributed into each workflow, and so on.
In more detail, in step 3, the cost data generated in the workflow are provided to financial monitoring and controlling tools 26. These are typically consumed by the financial side of the company, and used to monitor the business as a whole. As shown in step 5, financial analysis of the company may result in changes to multiple workflows and to business process, shown as block 30, as well as changes to the global financial model 11. Both types of changes are instantly reflected in the unified workflow and financial model 16 that is already deployed. A benefit of this embodiment is that data is current and cost modeling is continuously updated based on changes to workflow or to business processes, block 30, at the business unit or departmental level.
Referring now to
In particular, the workflow monitoring and controlling applications 24 are used to analyze results and propose changes to the workflow, shown in block 28. These workflow changes 28 are implemented, tested and employed. The unified workflow and financial model 16 is updated in tandem. One advantage of this feature is that cost data is continuously accumulated and the financial model remains valid without deep analysis of each change to the business process.

A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices) can be coupled to the system either directly or through intervening I/O controllers.
Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modems and Ethernet cards are just a few of the currently available types of network adapters.
The computer system can include a display interface 42 that forwards graphics, text, and other data from the communication infrastructure 40 (or from a frame buffer not shown) for display on a display unit 44. The computer system also includes a main memory 46, preferably random access memory (RAM), and may also include a secondary memory 48. The secondary memory 48 may include, for example, a hard disk drive 50 and/or a removable storage drive 52, representing, for example, a floppy disk drive, a magnetic tape drive or an optical disk drive. The removable storage drive 52 reads from and/or writes to a removable storage unit 54 in a manner well known to those having ordinary skill in the art. Removable storage unit 54, represents, for example, a floppy disk, a compact disc, magnetic tape, optical disk, etc. which is read by and written to by removable storage drive 52. As will be appreciated, the removable storage unit 54 includes a computer readable medium having stored therein computer software and/or data.
In alternative embodiments, the secondary memory 48 may include other similar means for allowing computer programs or other instructions to be loaded into the computer system. Such means may include, for example, a removable storage unit 56 and an interface 58. Examples of such may include a program cartridge and cartridge interface (such as that found in video game devices), a removable memory chip (such as an EPROM, or PROM) and associated socket, and other removable storage units 56 and interfaces 58 which allow software and data to be transferred from the removable storage unit 56 to the computer system.
The computer system may also include a communications interface 60. Communications interface 60 allows software and data to be transferred between the computer system and external devices. Examples of communications interface 60 may include a modem, a network interface (such as an Ethernet card), a communications port, or a PCMCIA slot and card, etc. Software and data transferred via communications interface 60 are in the form of signals which may be, for example, electronic, electromagnetic, optical, or other signals capable of being received by communications interface 60. These signals are provided to communications interface 60 via a communications path (i.e., channel) 62. This channel 62 carries signals and may be implemented using wire or cable, fiber optics, a phone line, a cellular phone link, an RF link, and/or other communications channels.
In this document, the terms “computer program medium,” “computer usable medium,” and “computer readable medium” are used to generally refer to media such as main memory 46 and secondary memory 48, removable storage drive 52 and a hard disk installed in hard disk drive 50.
