OMG-OCEB2-FUND100 OMG-Certified Expert in BPM 2 - Fundamental Question and Answers

In Six Sigma and statistical process control, which are often referenced within Object Management Group (OMG) Business Process Management practices for performance measurement and process capability analysis, variation in a process is categorized into two types:

Common cause variation (natural variation)

This is the inherent, stable variation built into the process.

It reflects the normal, expected fluctuations when the process is operating in a state of statistical control.

On a control chart, data points that reflect only common cause variationremain within the control limits (UCL and LCL)and do not exhibit specific non-random patterns.

Special cause variation (assignable variation)

This arises from specific, identifiable factors not normally part of the process (e.g., equipment failure, operator error, unusual input material).

On a control chart, it is typically indicated by pointsoutside the control limitsor by defined abnormal patterns (runs, trends, cycles) even if still inside the limits.

In the diagram shown:

The horizontal center line represents theprocess average.

The upper and lower horizontal lines representUCL (Upper Control Limit)andLCL (Lower Control Limit), typically set at ±3σ from the mean.

Zones A, B, and C mark bands of 1-sigma increments from the mean but are allwithinthe control limits.

From a standard Six Sigma / SPC standpoint, and consistent with how OMG-based BPM measurement and control concepts are applied:

All data points inside the UCL and LCLare considered to be a result ofcommon cause variation, provided they do not exhibit specific rule-violating patterns.

Data points outside the UCL or LCLare not common cause; they are indications ofspecial cause variationthat must be investigated and corrected.

InFragment A,Run Candy Productionis a subprocess with aboundary eventlabeledExtruder Stuck Onattached to it.

According to BPMN 2.0:

A boundary event attached directly to an activity/subprocess is evaluatedwhile that activity is executing.

When it triggers (here, when the “Extruder Stuck On” condition occurs), itinterruptsthe subprocess (for an interrupting boundary event) and the normal internal flow stops. Control is redirected along the boundary-event’s outgoing sequence flow (toward the alarm/handling path).

So, in Fragment A, the first time the extruder gets stuck during the execution ofRun Candy Production, that subprocess is interrupted and the alternate flow (e.g., cease production alarm, possibly skipping remaining steps inside the subprocess) is taken.

InFragment B, the “Extruder Stuck On?” is modeled as anExclusive Gatewayafter the internal tasks (afterConsume Excess and Substandard Candies). That means:

The condition ischecked only when the token reaches that gateway, i.e., after finishing the last internal task.

If “Yes”, we follow the alarm/cease path; if “No”, we continue to the normal completion/cleaning path.

This is exactly what optionDstates.

Options A and C say the fragments have the same or inverted behavior, which contradicts the execution semantics of boundary events vs. gateways.

Option B incorrectly assumes the boundary event is specifically an Error Event and misstates the validity of Fragment A. The fragment is valid BPMN; the key difference iswhen and howthe stuck-extruder condition is handled, captured correctly only by optionD.

BPMN (Business Process Model and Notation), as defined by the Object Management Group, is specifically agraphical notation for specifying business processes with well-defined execution semantics.

The standard describes how flow elements (events, activities, gateways, sequence flows, etc.) behave and how tokens move through a process – that is itsexecution semantics.

Strategy models, organization models, and business rules modelsare explicitlyout of scopeof BPMN itself, though BPMN models can be related to such artifacts through other OMG standards (e.g., BMM for motivation/strategy, or DMN for decision logic).

Therefore, among the options, onlyExecution semanticsis within BPMN’s defined scope.

In BMM,Influencersare factors—internal or external—that caninfluence an organization’s ability to achieve its Ends. They can be trends, events, conditions, or stakeholders.

The observation“Younger customers buying more Chilean wine”is a description of amarket trend/conditionin the environment.

That is exactly the role of anInfluencer: a situation or trend that may positively or negatively affect goals and strategies.

If the winery evaluates that trend (for example, calling it anOpportunity), that evaluation would be modeled as anAssessment. The raw trend itself is the Influencer.

Option A (Threat) is atypeof Assessment (negative evaluation of an Influencer).

Option C (Assessment) would be something like “The increased Chilean-wine preference among younger customers is an opportunity for our brand,” which adds judgment.

Option D (Course of Action) would be a response, such as “Launch a Chilean-style product line,” which is a Means, not the trend itself.

So the element“Younger customers buying more Chilean wine”is modeled as anInfluencerin BMM

Traditional (functional) work managementorganizes people and work bydepartments or specialties(e.g., Sales, Finance, HR, Operations). From an OMG BPM and value-chain perspective, the mainweaknessof this traditional model is that it:

Focuses onoptimizing individual functionsrather than optimizing theend-to-end processthat delivers value to customers.

Encourageslocal optimization(department KPIs) at the expense of global optimization (process performance, customer experience).

Createssilosand coordination issues across boundaries.

This is captured inOption D:

Lack of end-to-end focus

Why the other options are wrong:

A. Clear definition of roles and responsibilities– That is typically astrengthof functional management; roles are clearly defined within each department.

B. Functional excellence– Functional organizations often deliverstrong specialist expertise; again, that’s a strength, not a weakness.

C. Bad vision and mission– Vision and mission areenterprise-level strategic artifacts, not intrinsic to functional vs process structure.

Thus, the key structural weakness of traditional functional management is itslack of end-to-end focus, soDis correct.

===============

In BPMN,Activityis a generic term that covers:

Task– an atomic unit of work.

Sub-Process– a compound activity that contains a process within it.

AProcessisnotan Activity; it is a container of flow elements. “Action” is not a BPMN element at all. Therefore, the only correct list that consists solely of BPMN Activities is:

Task, Sub-Process

So the correct answer isB.

In the second diagram:

TheSurvey Processlane shows activities such asEmail RecipientsandOpen Email, encapsulated in a subprocess responsible for managing the survey.

TheCandidateslane showsReceive(getting the email) andNotify(sending back their response).

In theBPMSlane there is a “Business Rules for Survey” element linked (typically via an association) to the decision logic inside the subprocess, indicating that the evaluation of responses is governed by explicitbusiness rules.

Inside the subprocess, the “Survey Decision” gateway uses those rules to assess each response. There is a loop/counting mechanism (implicit or explicit) that repeats until anadequacy conditionis met. That adequacy is modeled as a combination ofnumber of responsesandwhether those responses satisfy the business rules, after which the process reaches its end event.

Now compare the options:

A.Mentions adequacy defined by business rules but says nothing about thenumberof acceptable responses.

B.Only tracks completion as responses arrive; no role for business rules or a target count.

C.Uses a predetermined number of responses, but doesn’t require that theysatisfy business rules.

D.Requires all responses to be filtered, not apredetermined numberof qualifying responses.

E.Explicitly states:

Email survey is sent to candidate recipients.

The survey is completed when apredetermined number of answers that satisfy business ruleshave been received.

That matches the BPMN model: responses are evaluated using business rules, counted, and the process ends when enoughacceptable(rule-compliant) responses have been collected.

Therefore,Eis the correct description of the process.

The left-hand diagram shows asub-process(container) that includes several activities (A, C, B) and hasone outgoing sequence flowto activity D. From the parent process’ point of view, this whole container behaves like asingle step that is complete only when all contained work is finished, after which control passes to D.

OptionBshows activities A and B executed inparallel(via an AND-gateway) and thenjoinedbefore proceeding to D. This has the same execution semantics from the outside:

All required internal activities must complete

Only then can the flow continue to D

The other alternatives represent different semantics:

Aimplies a particular loop/order between A, B, and D.

Cuses an exclusive gateway (only one branch executes).

Duses an event-based gateway (waiting for events, not all branches).

Thus,Option Bis the only diagram that executes identically from the perspective of when D is allowed to start.

In BPMN,Data Objectsare artifacts that show what data isusedorproducedby activities. They are connected usingData Associations, which are drawn asdashed/dotted lines with arrowheads:

Arrowfrom Data Object to Activity= the data is aninputto that activity.

Arrowfrom Activity to Data Object= the data is anoutputproduced by that activity.

Looking at the options:

Option AshowsTask Awith:

A dashed association arrow fromData Object 1 to Task A(Data Object 1 is input).

A dashed association arrow fromTask A to Data Object 2(Data Object 2 is output).This matches BPMN rules exactly and is a canonical textbook example of input and output data objects for a task.

Option Bshows both data objects associated as outputs only (arrows from Task A to both), which would not reflect the typical input–output pattern and is generally not the intended “correct” example for demonstrating BPMN data object usage.

Options C and Dinvolve attaching a data object to a sequence flow. While BPMN allows associating a data object to a sequence flow as shorthand, the official specification states that when associating an artifact with asequence or message flow, the association is normallynon-directional(no arrowheads), because the flow itself already shows direction. One of these options uses directional arrows incorrectly, and thus these are not preferred as the “correct” representation in a strict exam context.

Given the OMG specification and common BPMN teaching examples,Option Ais the clearly correct and standards-compliant diagram for data objects and data associations.

In the BMM,Directives(i.e., Business Policies and Business Rules) are used togovern how the enterprise actsto achieve its Ends.

BMM breaks down:

Meansinto:

Mission

Courses of Action(Strategies and Tactics)

Directives(Business Policies and Business Rules)

The specification states thatBusiness Policies (a type of Directive) exist to govern – control, guide, and shape – Strategies and Tactics, which together are theCourses of Action. Business Rules, derived from these policies, provide precise, enforceable guidance for their execution.

Thus,Directives govern Courses of Action, not Goals, Assessments, or Business Policies (Business Policies themselves are a type of Directive).

So the correct answer isCourses of Action.

In OMG BPM terminology,process complexityis driven by the number ofdecision points, dependencies, and paths the process may take.

Thenumber of branches(e.g., gateways, conditional flows) directly increases structural complexity since it multiplies possible execution paths.

OptionBmatches this exactly.

OptionA(steps) increases length, not necessarily complexity.

OptionC(instances) relates to workload, not structural complexity.

OptionDrefers to user volume, unrelated to process model complexity.

Thus,branches are the main structural complexity driver in BPMN models.

Process topology refers to thesequence and structureof activities—the flow of tasks.

The only option that directly discoversprocess flow and orderingis:

✔C: Discovering the previous and next tasksfor each task.

This is a classic method in BPM to reconstruct the end-to-end process and map dependencies.

Other options focus on metrics, decisions, or data—not thestructural topology.

The diagram shows:

ActivityA, then

Aparallel gatewaythat fans out to three branches (B, C, D), and

Aparallel gatewaythat joins all three beforeE.

This means:

After A, the process may carry outB,C, andDin parallel (or at least independently).

All active branches must complete before moving toE.

Scenario C fits this pattern:

A = enter primary recipients

B = optionally add cc-recipients

C = write the email text

D = optionally add attachments

E = send email

The optional activities (cc and attachments) can be done in any order while writing the text, but all work is complete before sending. The other scenarios are essentially linear or don’t naturally occur in parallel like this.

The diagram shows:

ActivityA

Followed by agateway(a plain diamond – the defaultexclusive data-based gatewayin BPMN)

With two outgoing flows, one toBand one toC, and no join afterward.

Anexclusive gateway(XOR) means:

Exactly oneoutgoing branch is taken based on a condition.

So the semantics:

First doA,

Then evaluate a condition,

Then executeeither B or C (but not both)depending on that condition.

Mapping to the choices:

A. Wait for an event→ would require anevent-based gateway, not shown.

B. B and C in any order→ would require aparallel gateway.

C. B or C depending on a condition→ matches anexclusive data-based gateway.

D. B or C or both→ that is aninclusive (OR) gateway, which uses a circle marker, not shown here.

Thus, the correct scenario isC: First do A, then B or C depending on a condition.

In BPMN, aText Annotationis anartifactused purely to add explanatory comments to elements in a diagram. Itnever affects the process flow or execution semantics. OMG specifies that artifacts, including Text Annotations, are connected to flow objects (activities, events, gateways, sequence flows, etc.) usingAssociations, which are dotted (or dashed) lines. The association may be directional or non-directional, but it is still anAssociation, not a Sequence Flow or Message Flow.

Therefore:

Option A is false because Text Annotations donotaffect process flow.

Option B is false because a Text Annotation may be connected toanyflow object (and even to flows), not only to pools, lanes, or groups.

Option C correctly states that a Text Annotation is connected by anAssociation.

Option D is about its graphic shape, but the question asks for adescriptionthat is true in general, which is precisely captured by Option C.

So,Cis the correct answer in accordance with the OMG BPMN 2.0.2 specification.

The library scenario has these mutually exclusive branches afterCheck Book Availability:

Book available here→ directlyBorrow Book.

Borrowed by other user→Reserve Book→ wait untilBook returned(message) →Borrow Book.

Available at other location→Order Book→ wait untilBook arrived(message) →Borrow Book.

So the BPMN needs:

Anexclusive gatewayafter “Check Book Availability” to choose exactly one of three paths.

Message intermediate eventson the “reserved” and “ordered” paths.

Asimple merge(exclusive gateway) before “Borrow Book” since only one branch will be active.

Among the options,Option Bis the one that uses exclusive branching for the three conditions and merges them correctly before “Borrow Book” while modeling the two asynchronous waits with message intermediate events.

Porter’s Five Forcesis a classicstrategic analysis frameworkfrequently referenced inbusiness architecture and BPMto understand the external environment that shapes processes and strategies.

The five forces are:

Barriers to entry / Threat of new entrants– How easy is it for new competitors to enter the market?

Threat of substitute products or services– Can customers switch to something different that satisfies the same need?

Bargaining power of suppliers– How much power do suppliers have over price, quality, and terms?

Bargaining power of customers (buyers)– How much power do customers have to push prices down or demand more value?

Competitive rivalry within the industry– Intensity of competition among current players.

OMG’sBusiness Motivation Model (BMM)and enterprise strategy views use these kinds of external assessments to drive:

Ends(goals, objectives).

Means(strategies, tactics).

Resultingbusiness processesmodeled in BPMN.

Why the other options are incorrect:

A, C, and Dmix in elements ofstrategic planning steps,value chain analysis, orgoal setting, but none of them match the canonical list of the Five Forces.

Thus, the correct set of Porter’s Five Forces is exactly what is listed inOption B.

AnExpanded Sub-Process without Sequence Flows between its Tasksis interpreted as anAd-Hoc Sub-Process, provided it is marked as such (with the ad-hoc tilde marker). In BPMN / OMG terms, an ad-hoc sub-process:

Hasno predefined execution orderbetween its contained activities.

Allows activities to be performedin any order, possibly

multiple times,

not at all,

or in parallel.

Continues until somecompletion conditionis satisfied or the process decides to end that sub-process.

This is exactly what optionCdescribes.

OptionAandDimpose ordering or “exactly-once” semantics that BPMN doesnotdefine for an ad-hoc sub-process.

OptionBis incorrect because BPMN explicitly allows ad-hoc subprocesses where tasks are not connected by sequence flows.

Therefore,Cis the correct interpretation.

Straight-through-processing (STP)refers toend-to-end automationwhere a process instance flows through the systemwithout any human intervention.

OptionAis the precise definition used in BPM and BPMS literature.

In BPMN, anEnd Eventrepresents the point where a particularexecution pathin the process terminates. A process may have multiple end events, each ending a different path.

It isnotmerely a pointer to the last activity (A).

It isnot necessarilythe last event generated by the entire process (C), because multiple paths can end independently.

It isnotthe connection point between a Sub-Process and its parent (D); that is the role of the Sub-Process’s boundaries.

So the correct conceptual definition is that an End Eventmarks the end of a path through a process.

Chang states clearly thatInformation Technology (IT)is thekey enablerof Business Process Re-engineering (BPR), as it allows radical redesign of processes rather than incremental improvement.

HenceCis correct.

In a Business Process Management System (BPMS), aworklist handler(or worklist manager) coordinates human tasks. It serves as the interface where:

Task assignments are offered

Users select/claim tasks

Work items are distributed based on rules

This aligns with OMG's description of human task management in BPMN and BPMS architectures.

OptionCaccurately represents that a worklist handleroffers work items to participants.

OptionArefers to monitoring/reporting.

OptionBrefers to organizational modeling, not worklist handling.

OptionDdescribes auser’s personal task list, but not the handler’s role.

By BPMN rules,Message Flowsare usedonly between different participants (different Pools). You cannot use a Message Flow between Flow Objects inside the same Pool; inside a Pool you must useSequence Flowinstead. Therefore, optionCstates the valid constraint.
