'''Business process modeling''' ('''BPM''') is the action of capturing and representing [[business processes|processes]] of an enterprise (i.e. [[modeling]] them), so that the current business processes may be analyzed, applied securely and consistently, improved, and automated.

BPM is typically performed by business analysts, with subject matter experts collaborating with these teams to accurately model processes. It is primarily used in [[business process management]], [[software development]], or [[systems engineering]].

[[File:Fife-Disciplines-Of-The-BPM.png|thumb|The five disciplines of business process management and their relationships]]

According to the Association of Business Process Management Professionals (ABPMP), business process modeling is one discipline of the five key disciplines within [[business process management|Business Process Management]] that comprises the following five disciplines:(BPM).<ref name="EABPM">Association of Business Process Management Professionals ABPMP (publisher): ''Guide to the Business Process Management common body of knowledge - BPM CBOK®'' in the translated and edited German edition of → European Association of Business Process Management EABPM (publisher): ''Business Process Management Common Body of Knowledge - BPM CBOK®'', 2nd version, Verlag Dr. Götz Schmidt, Gießen 2009, ISBN 978-3-921313-80-0</ref> ^{(Chapter 1.4 CBOK® structure) ← automatic translation from German} The five disciplines are:

* Process modeling : Creating visual or structured representations of business processes to better understand how they work.

* Process modeling

* Process analysis (: understanding the as-is processes and their alignment with the company's objectives -– analysis of business activities).

* Process design (: redesign -– business process reengineering -– or redesign of business processes -– business process optimization).

* Process performance measurement (: can focus on the factors of time, cost, capacity, and quality or on the overarching view of [[Kaizen#The seven Muda|waste]]).

* Process transformation (: planned, structured development, technical realization, and transfer to ongoing operations).

However, athese completelydisciplines separatecannot consideration of the disciplinesbe isconsidered notin possibleisolation: Business process modeling always requires a ''business process analysis'' for modeling the as-is processes (see section [[#Analysis of business activities|Analysis of business activities]]) or specifications from ''process design'' for modeling the to-be processes (see sections [[#Business process re-engineering (BPR)|Business process reengineering]] and [[#Business process optimization|Business process optimization]]).

The focus of business process modeling is on the [[#Representation type and notation|representation]] of the flow of [[Action (philosophy)|actions (activities)]], according to Hermann J. Schmelzer and Wolfgang Sesselmann consisting "of the cross-functional identification of value-adding activities that generate specific services expected by the customer and whose results have strategic significance for the company. They can extend beyond company boundaries and involve activities of customers, suppliers, or even competitors."<ref name="SCHMELZER">Hermann J. Schmelzer and Wolfgang Sesselmann: ''Geschäftsprozessmanagement in der Praxis'', 9th edition, Hanser, Munich 2020, ISBN 978-3-446-44625-0</ref> ^{(Chapter 2.1 Differences between processes and business processes) ← automatic translation from German}

Line 27:

But also other [[Quality (philosophy)|qualities]] (facts) such as [[data]] and [[business object]]s (as inputs/outputs, [[formal organization]]s and [[Actor (UML)|roles]] (responsible/accountable/consulted/informed persons, see [[Responsibility assignment matrix|RACI]]), [[resource]]s and [[application software|IT-systems]] as well as [[guideline]]s/instructions ([[Means of labor|work equipment]]), [[requirement]]s, [[Performance indicator|key figure]]s etc. can be modeled.

"To reduce complexity and improve the comprehensibility and transparency of the models, the use of a view concept is recommended."<ref name="GADATSCH">Andreas Gadatsch: ''Management von Geschäftsprozessen / Methoden und Werkzeuge für die IT-Praxis: Eine Einführung für Studenten und Praktiker'', 2nd revised and expanded edition, Vieweg, Braunschweig/Wiesbaden 2002, ISBN 978-3-528-15759-3</ref>^{(Chapter 2.4 Views of process modeling) ← automatic translation from German} There is also a brief comparison of the view concepts of five relevant German-speaking schools of [[business informatics]]: 1) August W. Scheer, 2) Hubert Österle, 3) Otto K. Ferstl and Elmar J. Sinz, 4) Hermann Gehring and 5) Andreas Gadatsch.

The term ''view''s ([[August-Wilhelm Scheer|August W. Scheer]], Otto K. Ferstl and Elmar J. Sinz, Hermann Gehring and Andreas Gadatsch) is not used uniformly in all schools of business informatics -– alternative terms are ''design dimensions'' (Hubert Österle) or ''perspectives'' (Zachman).

M. Rosemann, A. Schwegmann, and P. Delfmann also see disadvantages in the ''concept of views'': "It is conceivable to create information models for each perspective separately and thus partially redundantly. However, redundancies always mean increased maintenance effort and jeopardize the consistency of the models."<ref name="ROSEMANN">Michael Rosemann, Ansgar Schwegmann and Patrick Delfmann: ''Vorbereitung der Prozessmodellierung'' in Jörg Becker, Martin Kugler and Michael Rosemamm (publisher): ''Prozessmanagement: Ein Leitfaden zur prozessorientierten Organisationsgestaltung'', 2nd corrected and expanded edition, Springer, Berlin/Heidelberg/New York 2002, ISBN 978-3-540-00107-2</ref> ^{(Chapter 3.2.1 Relevant perspectives on process models) ← automatic translation from German}

According to Andreas Gadatsch, ''business process modeling is understood as a part of business process management alongside process definition and process management''.<ref name="GADATSCH" /> ^{(Chapter 1.1 Process management) ← automatic translation from German}

Business process modeling is also a central aspect of holistic company mapping -– which also deals with the mapping of the [[Mission statement|corporate mission statement]], corporate policy/[[corporate governance]], organizational structure, process organization, [[enterprise architecture|application architecture]], regulations and interest groups as well as the [[Market (economics)|market]].

[[File:Core_process_(quality_management).gif|thumb|Typical breakdown of a '''process map''' into management, core and support processes]]

According to the European Association of Business Process Management EABPM, "there are three different types of end-to-end business processes:

* Leadership processes;

* Execution processes and

* Support processes."<ref name="EABPM"/> ^{(Chapter 2.4 Process types) ← automatic translation from German}

These three process types can be identified in every company and are used in practice almost without exception as the top level for structuring business process models.<ref>Knowledge database: [https://der-prozessmanager.de/aktuell/wissensdatenbank/prozesslandkarte ''In 6 einfachen Schritten zur Prozesslandkarte''], DER PROZESSMANAGER GmbH (last accessed: January 25, 2024)</ref> Instead the term ''leadership processes'' the term ''[[management process]]es'' is typically used.

In the field of [[software engineering]], the term ''business process modeling'' opposed the common [[software process]] modeling, aiming to focus more on the state of the practice during [[software development]].<ref>Brian C. Warboys (1994). ''Software Process Technology: Third European Workshop EWSPT'94'', Villard de Lans, France, February 7–9, 1994: Proceedings. p. 252.</ref> In that time (the early 1990s) all existing and new modeling techniques to illustrate business processes were consolidated as 'business process [[modeling language]]s'{{Citation needed|date = April 2014}}. In the [[Object Oriented]] approach, it was considered to be an essential step in the specification of business application systems. Business process modeling became the base of new methodologies, for instance, those that supported [[data collection]], data flow analysis, process flow diagrams, and reporting facilities. Around 1995, the first visually oriented tools for business process modeling and implementation were presented.

== Objectives of business process modeling ==

[[File:Influencing-factors-on-the-business-process-model.png|thumb|Influencing factors on the business process model]]

The objective of business process modeling is a -– usually graphical -– representation of end-to-end processes, whereby complex facts of reality are documented using a uniform (systematized) representation and reduced to the substantial (qualities). Regulatory requirements for the documentation of processes often also play a role here (e.g. [[document control]], [[Requirements traceability|traceability]], or [[integrity]]), for example from [[quality management]], [[information security management system|information security management]] or [[Information privacy|data protection]].

Business process modeling typically begins with determining the environmental requirements: First, the [[goal]] of the modeling ([[#Applications of business process modeling|applications of business process modeling]]) must be determined. Business process models are now often used in a multifunctional way (see above). Second the model addressees must be determined, as the properties of the model to be created must meet their requirements. This is followed by the determination of the business processes to be modeled.

Line 96:

* [[Modularity|Modularization]] of company processes

* [[Benchmarking]] between parts of the company, partners and competitors

* Performing [[activity-based costing]] and [[simulation|simulations]]s

** to understand how the process reacts to different stress rituals or expected changes

** to evaluate the effectiveness of measures for ''business process optimization'' and compare alternatives

* Finding the [[best practice]]

* Accompanying organizational changes

** such as the sale or partial sale

** such as the acquisition and integration of companies or parts of companies

** such as the introduction or change of IT systems or organizational structures

* Participation in competitions (such as [[European Foundation for Quality Management|EFQM]]).

== Applications of business process modeling ==

Since business process modeling in itself makes no direct contribution to the financial [[Profit (economics)|success]] of a company, there is no motivation for business process modeling from the most important goal of a company, the [[For-profit corporation|intention to make a profit]]. The motivation of a company to engage in business process modeling therefore always results from the respective purpose. ''Michael Rosemann, Ansgar Schwegmann und Patrick Delfmann'' listlists a number of purposes as motivation for business process modeling:

* Organizational ''documentation'', with the "objective of increasing transparency about the processes in order to increase the efficiency of communication about the processes"<ref name="ROSEMANN"/> ^{(Chapter 3.2.1 Relevant perspectives on process models) ← automatic translation from German,}<ref name="GADATSCH"/> ^{(Chapter 2.5.4 Areas of application for process modeling in practice) ← automatic translation from German} including the ability to create process templates to relocate or replicate business functions or the objective to create a complete company model

* Process-oriented ''re-organization'', both in the sense of "(revolutionary) [[business process re-engineering]] and in the sense of [[Continual improvement process|continual (evolutionary) process improvement]]"<ref name="ROSEMANN" /> ^{(Chapter 3.2.1 Relevant perspectives on process models) ← automatic translation from German} with the objective of a [[vulnerability assessment]]<ref name="GADATSCH"/> ^{(Chapter 2.5.4 Areas of application for process modeling in practice) ← automatic translation from German}, ''process optimization'' (e.g. by controlling and reducing total cycle time<ref name="MILTENBURG-SPARLING">John Miltenburg, David Sparling: ''Managing and reducing total cycle time: models and analysis'' in Elsevier ''International Journal of Production Economics'', December 1996, Pages 89-108</ref> (TCT), through [[Kaizen]], [[Six Sigma]] etc.) or ''process standardization''

Line 165:

* Retain documented information for correct implementation

The implementation of the standard requirements for the ''processes needed and their interactions'' and, in particular, proof of the implementation of the standard requirements with adequate documentation (business process modelling) is common practice. This also means that the standard requirements for ''documented information'' are also relevant for business process modelling as part of an ISO management system.

==== Specific standard requirements for management systems with regard to documented information ====

Line 181:

* To ensure suitable and available at the place and time as required;

* To ensure protection (e.g. against loss of confidentiality, improper use or loss of integrity);

* To consider distribution, access, retrieval, and use;

* To consider filing/storage and preservation (including preservation of readability);

* To perform monitoring of changes (e.g. version control); and

Line 204:

When examining Kaizen tools, initially, there is no direct connection to business processes or business process modeling. However, Kaizen and business process management can mutually enhance each other. In the realm of business process management, Kaizen's objectives are directly derived from the objectives for business processes and sub-processes. This linkage ensures that Kaizen measures effectively support the overarching business objectives."<ref name="SCHMELZER" /> ^{(Chapter 6.3.3 KAIZEN) ← automatic translation from German}

Six Sigma is designed to prevent errors and improve the [[Process capability index|process capability]] so that the proportion of process outcomes that meet the requirements is 6σ -– or in other words, for every million process outcomes, only 3.4 errors occur. Hermann J. Schmelzer and Wolfgang Sesselmann explain: "Companies often encounter considerable resistance at a level of 4σ, which makes it necessary to redesign business processes in the sense of business process re-engineering (design for Six Sigma)."<ref name="SCHMELZER" /> ^{(Chapter 6.3.4 Six Sigma) ← automatic translation from German} For a reproducible measurement of process capability, precise knowledge of the business processes is required and business process modeling is a suitable tool for design for Six Sigma. Six Sigma, therefore, uses business process modeling according to [[SIPOC]] as an essential part of the methodology, and business process modeling using SIPOC has established itself as a standard tool for Six Sigma.

=== Inter-company business process modeling ===

Line 217:

The analysis of business activities determines and defines the framework conditions for successful business process modeling. This is where the company should start,

* define the relevant ''applications'' of business process modeling on the basis of the [[business model]] and where it is positioned in the [[value chain]],

* derive the ''strategy for the long-term success of business process modeling'' from the [[business strategy]] and develop an approach for structuring the business process models. Both the relevant ''purposes'' and the ''strategy'' directly influence the [[process map]].

This ''strategy for the long-term success of business process modeling'' can be characterized by the market-oriented view and/or the resource-based view. ''Jörg Becker and Volker Meise'' explain: "Whereas in the market view, the industry and the behavior of competitors directly determine a company's strategy, the resource-oriented approach takes an internal view by analyzing the strengths and weaknesses of the company and deriving the direction of development of the strategy from this."<ref name="BECKER-MEISE"/> ^{(Chapter 4.6 The resource-based view) ← automatic translation from German} And further: "The alternative character initially formulated in the literature between the market-based and resource-based view has now given way to a differentiated perspective. The core competence approach is seen as an important contribution to the explanation of success potential, which is used alongside the existing, market-oriented approaches."<ref name="BECKER-MEISE"/>^{(Chapter 4.7 Combination of views) ← automatic translation from German} Depending on the company's strategy, the ''process map'' will therefore be the business process models with a view to market development, with a viewand to resource optimization or in a balanced manner.

==== Identify business processes ====

Line 233 ⟶ 231:

[[File:Core_process_(quality_management).gif|thumb|Typical breakdown of a '''process map''' into management, core and support processes]]

==== Structure business processes -– building a process map ====

''Timo Füermann'' explains: "Once the business processes have been identified and named, they are now compiled in an overview. Such overviews are referred to as process maps."<ref name="FUEERMANN">Timo Füermann: ''Prozessmanagement: Kompaktes Wissen, Konkrete Umsetzung, Praktische Arbeitshilfen'', Hanser, München 2014, ISBN 978-3-446-43858-3</ref> ^{(Chapter 2.4 Creating the process map) ← automatic translation from German}

Line 281 ⟶ 279:

The scope of a business process should be selected in such a way that it contains a manageable number of sub-processes, while at the same time keeping the total number of business processes within reasonable limits. Five to eight business processes per business unit usually cover the performance range of a company.

Each business process should be independent -– but the processes are interlinked.

The definition of a business process includes: What result should be achieved on completion? What activities are necessary to achieve this? Which objects should be processed (orders, raw materials, purchases, products, ...)?

Depending on the prevailing corporate culture, which may either be more inclined towards embracing change or protective of the status quo and the effectiveness of communication, defining business processes can prove to be either straightforward or challenging. This hinges on the willingness of key stakeholders within the organization, such as department heads, to lend their support to the endeavor. Within this context, effective communication plays a pivotal role.

In elucidating this point, Jörg Becker and Volker Meise elucidate that the communication strategy within an organizational design initiative should aim to garner support from members of the organization for the intended structural changes. It is worth noting that business process modeling typically precedes business process optimization, which entails a reconfiguration of process organization -– a fact well understood by the involved parties. Therefore, the communication strategy must focus on persuading organizational members to endorse the planned structural adjustments."<ref name="BECKER-MEISE" /> ^{(Chapter 4.15 Influencing the design of the regulatory framework) ← automatic translation from German} In the event of considerable resistance, however, external knowledge can also be used to define the business processes.

Line 299 ⟶ 297:

=== Further structuring of business processes ===

[[File:VAC-production-company4.png|thumb|Example of the decomposition of a business process into sub-processes -– supplemented by milestones, business units, data objects and IT-systems]]

The rough structure of the business processes created so far will now be decomposed -– by breaking it down into sub-processes that have their own attributes but also contribute to achieving the goal of the business process. This decomposition should be significantly influenced by the ''application'' and ''strategy for the long-term success of business process modeling'' and should be continued as long as the tailoring of the sub-processes defined this way contributes to the implementation of the ''purpose'' and ''strategy''.

A sub-process created in this way uses a [[Scientific modelling|model]] to describe the way in which procedures are carried out in order to achieve the intended operating goals of the company. The model is an abstraction of reality (or a target state) and its concrete form depends on the intended use (application).

Line 306 ⟶ 304:

A further decomposition of the sub-processes can then take place during [[#Modeling business process|business process modeling]] if necessary. If the business process can be represented as a sequence of phases, separated by [[Milestone (project management)|milestones]], the decomposition into phases is common. Where possible, the transfer of milestones to the next level of decomposition contributes to general understanding.

The result of the further structuring of business processes is usually a hierarchy of sub-processes, represented in value chain diagrams. It is common that not all business processes have the same depth of decomposition. In particular, business processes that are not safety-relevant, cost-intensive or contribute to the operating goal are broken down to a much lesser depth. Similarly, as a preliminary stage of a decomposition of a process planned for (much) later, a common understanding can first be developed using simpler / less complex means than ''value chain diagrams'' -– e.g. with a textual description or with a turtle diagram<ref name="FUEERMANN" /> ^{(Chapter 3.1 Defining process details) ← automatic translation from German} (not to be confused with [[Turtle graphics|turtle graphic]]!).

=== Assigning the process responsibility ===

[[File:Pyramid-of-process-responsibility.png|thumb|Sample for a pyramid of process responsibility]]

Complete, self-contained processes are summarized and handed over to a responsible person or team. The ''[[Ownership|process owner]]'' is responsible for success, creates the framework conditions, and coordinates his or her approach with that of the other process owners. Furthermore, he/she is responsible for the exchange of information between the business processes. This coordination is necessary in order to achieve the overall goal orientation.

=== Modeling business process ===

Line 349 ⟶ 347:

They also list five basic principles that have proven their worth in the creation of ''to be'' models:

* Parallel processing of sub-processes and individual activities is preferable to sequential processing -– it contains the greater potential for optimization.

* The development of a sub-process should be carried out as consistently as possible by one person or group -– this allows the best model quality to be achieved.

* Self-monitoring should be made possible for individual sub-processes and individual activities during processing -– this reduces quality assurance costs.

* If not otherwise possible, at least one internal customer/user should be defined for each process -– this strengthens customer awareness and improves the assessability of process performance.

* Learning effects that arise during the introduction of the target processes should be taken into account -– this strengthens the employees' awareness of value creation.

The business process model created by ''as is modeling'' or ''to be modeling'' consists of:

Line 430 ⟶ 428:

For example, direct access to objects in a [[knowledge database]] or documents in a [[Business rule|rule framework]] can significantly increase the benefits of the business process model in everyday life and thus the acceptance of business process modeling. All IT-systems involved can exploit their specific advantages and cross-fertilize each other (e.g. link to each other or standardize the filing structure):

* short response times of the knowledge database; characterized by a relatively high number of auditors, very fast adaptation of content, and low requirements for the publication of content -– e.g. realized with a [[wiki]]

* Legally compliant documents of the rule framework; characterized by a very small number of specially trained auditors, validated adaptation of content, and high requirements for the release of content -– e.g. implemented with a [[document management system]]

* Integrating graphical representation of processes by a BPM system; characterized by a medium number of auditors, moderately fast adaptation of content, and modest requirements for the release of content

Line 494 ⟶ 492:

=== Modelling techniques ===

There are various standards for notations; the most common are:

* Business Process Model and Notation (BPMN), proposed in 2002 by Stephen A. White, published by the Business Process Management Initiative -– merged in June 2005 with [[Object Management Group]]

* [[Event-driven process chain]] (EPC), proposed in 1992 by a working group under the leadership of August-Wilhelm Scheer

* ''Value-added chain diagram'' ([[:de:Wertsch%C3%B6pfungskettendiagrammWertschöpfungskettendiagramm|VAD]]), for visualizing processes mainly at a high level of abstraction

* [[Petri net]], developed by [[Carl Adam Petri]] in 1962

* Follow-up plans (e.g. in the specific form of a [[Flowchart]]), proposed in 1997 by Fischermanns and Liebelt

=== Tools ===

Business process modelling tools provide business users with the ability to model their business processes, implement and execute those models, and refine the models based on as-executed data. As a result, business process modelling tools can provide transparency into business processes, as well as the centralization of corporate business process models and execution metrics.<ref name="NIH07">[http://enterprisearchitecture.nih.gov/ArchLib/AT/TA/WorkflowServicePattern.htm Workflow/Business Process Management (BPM) Service Pattern] {{webarchive|url=https://web.archive.org/web/20090113184950/http://enterprisearchitecture.nih.gov/ArchLib/AT/TA/WorkflowServicePattern.htm |date=2009-01-13}} June 27, 2007.

Usually, a business model is created after conducting an interview, which is part of the [[business analysis]] process. The interview consists of a facilitator asking a series of questions to extract information about the subject business process. The interviewer is referred to as a facilitator to emphasize that it is the participants, not the facilitator, who provide the business process information. Although the facilitator should have some knowledge of the subject business process, but this is not as important as the mastery of a pragmatic and rigorous method interviewing business experts. The method is important because for most enterprises a team of facilitators is needed to collect information across the enterprise, and the findings of all the interviewers must be compiled and integrated once completed.<ref name="SS93"/>

Business models are developed asto definingdefine either the current state of the process, resulting in which case the final product is called the "'as is"' snapshot model, or a conceptvision of what the process should becomeevolve into, resultingleading into a "'to be"' model. By comparing and contrasting "the 'as is"' and "'to be"' models the, business analysts can determine if the existing business processes and information systems are sound and only needrequire minor modifications, or if reengineering is requirednecessary to correctenhance problemsefficiency. orAs improvea efficiency. Consequentlyresult, business process modeling and subsequent analysis can be used to fundamentally reshape the way an enterprise conducts its operations.<ref name="SS93"/>
