The first sentence on page 171 states:
The User Task inherits the attributes and model associations of Activity (see Table 10.3), but does not have any
additional attributes or model associations.

I think that in the mentioned sentence "User Task" should be replaced by "Manual Task".
The sentence is still in the section of the Manual Task and the User Tasks starts afterwards also providing its own statement stating that the User Task inherits the attributes and model associtations of Activity.

It says:
“Both Sub-Choreographies can have standard loops and multi-instances. Examples of Choreography Activities with the appropriate markers can be seen in Figure 11.12 and Figure 11.22.”

The purpose of this paragraph is to explain that both Choreography Task and Sub-Choreography can have loop markers. Figure 11.12 shows Choreography Task Markers, and Figure 11.22 shows Sub-Choreography Markers

Then, it should say:
“Both Choreography Activities can have standard loops and multi-instances. Examples of Choreography Activities with the appropriate markers can be seen in Figure 11.12 and Figure 11.22.”

“Sub-Choreographies” should be replaced by “Choreography Activities”

The following text is from page 280:
There are three (3) variations of None
Events: a Start Event, a catch Intermediate Event, and an End Event (see Figure 10.91).

The catch None Intermediate Event MUST only be used in normal flow and, thus, MAY NOT be attached to the boundary of an Activity.

However, according to Table 10.93 and the former text, a None-Trigger is allowed for a Start Event, End Event and for a throw Intermediate Event but not for a catch Intermediate Event.

I was going through the BPMN 2.0 Specifications and found some conflicting
content regarding choreographies. In section 7.4 Use of Text, Color, Size,
and Lines in a Diagram, the third indented point of the bullet "The fills
that are used for the graphical elements MAY be white or clear" states
that "Participant Bands for Choreography Tasks and Sub-Choreographies that
are not the initiator of the activity MUST have a light fill. This does
not seem to be consistent with what is depicted in Figure 7.7 An example
of a stand-alone choreography diagram. It is also not consistent with the
discussions on Choreography in the same document in Section 11.4.1
Choreography Task.

Page 203, Table 10-26, multiInstanceLoopCharacteristics: I believe that the motivation behind having events thrown in coordination with the completion of instances of multiInatnce activity is to have non-interrupting boundary events to carry out some desired ackownledgements (or other defined activites), but if the catching boudnary event is interrupting, the alternate flow will be followed potentially resulting in un-expected or suspected behavior.

What is the intended use case if the catching boudnary event is interrupting?

The design of the MI activity was done with the use case in mind that the catching boundary event is non-interrupting.
However, we do not see a strong reason to rule out that the catching boundary event could be interrupting.

The Beta-1 CMOF files on the server (spec/BPMN/2.0/20090501/cmof.xmi <http://www.omg.org/spec/BPMN/2.0/20090501/cmof.xmi>, spec/BPMN/2.0/20090501/Infrastructure.xmi <http://www.omg.org/spec/BPMN/2.0/20090501/Infrastructure.xmi>, spec/BPMN/2.0/20090501/Semantic.xmi <http://www.omg.org/spec/BPMN/2.0/20090501/Semantic.xmi>) are invalid in several ways:

(1) The schemaLocation for the UML Infrastructure schema is an EMF URI that returns Error 404. The only elements actually used in the BPMN model are the primitive types. It is preferable to provide only the standard UML URI and assume that any CMOF implementation will have a known source for it.

(2) The modularization of the Infrastructure Package makes no sense.
The Infrastructure Package must import Core::Foundation in order to define the associations from Definitions to RootElements, Relationships, and Extensions. Otherwise those data types are undefined. And in the current model, only the association ends owned by Definitions are in the Infrastructure Package; the associations themselves and the non-navigable ends are owned by the Foundation Package.
[It is not clear what religious motive caused Infrastructure to be removed from the Core Package in the first place. It is documented as part of the Core in the specification. Definitions is a subclass of BaseElement and inheriting the identifier documentation is important.
If you really want to separate Definitions (and Imports) for some reason, then you need to split Definitions into an Infrastructure version containing only the properties that are wholly contained in the Infrastructure package and a Core version that has the properties that bind Definitions to Foundation elements, including the generalization, and then packageMerge Infrastructure into Core. But then the "reusable" thing in the Infrastructure package has neither a formal id, nor any associated text.]

(3) Foundation should import the "cmof" Package (which should really be the OMG standard reference) to define Element, for external Relationships and Extensions.

(4) Infrastructure should import the "interchange" Package that "defines" Diagram, and the "interchange" module should define the class Diagram, not the class NotInSpec. I realize that this is a fudge, but the existing nonsense causes Definitions:diagrams to be a model inconsistency when loading the XMI file into a CMOF repository.

Yes, it is difficult to get a correct CMOF file out of the EMF libraries, or any UML tool. But it is the only form on the OMG server that can be loaded into a model library for integration with other cmof:Element objects (e.g., from UML or UPDM or SysML or BMM models).
The XML schemas are worthless for this purpose. So, if you want Extension to work, fix the CMOF file.

When a single semantic element has multiple depictions (e.g. DataObjects), this forces the requirement for the target and source information to be duplicated in the DI schema in oder to know where to draw the association (i.e to which instance).

In the case of DatStore, the solution was to have only one semantic element dataStore and have dataSoreRefs as depictable duplicate elements.

Maybe the same could be explored for DataObjects

When a Depictable element does not have a semantic element to reference, this forces the DI to duplicate target and source information in the schema in order to properly depict such elements.

The example is provided to showcase human performers.

Figure 10-22 incorrectly depicts a pool in a process diagram. It should be a lane named: Buyer. (i.e. remove the line seperating the label Buyer from its content)

Table 10-19 provide an incorrect serialization. There should be a laneset element with a single lane named : Buyer.

The use of the string Buyer as process id is also very misleading.

This example should be completly revalidated for correctness....critical because it is the only example of a serialization of the semantic of a process.

Currently, a Business Rule Task has only an "implementation" attribute that is used to identify the technology used to interact/communicate with a rule engine (e.g. Web Service or any other protocol).

However, there is no possibility to identify to which rule engine the data should be sent nor which rule set should be processed. I believe that this information is crucial from a vendor perspective.

My suggestion is to add an anyURI-attribute called "ruleSet" (perhaps there is more generic term). The attribute's value can be resolved at runtime/deployment time by BPMS to identify both, rule engine and ruleset or other rule engine specific settings.

Since the business rule task is underspecified, vendor specific extensions are needed anyway. So there is no real value in adding any additional attribute, since
interoperability will not be possible.

The spec has two confusing statements for Terminate End Event:

In section 10.4.3: Terminate: This type of End indicates that all activities in the Process should be immediately ended. This includes all instances of Multi-Instances. The Process is ended without compensation or event handling.

In section 14.4.6: Sub-process level end events: For a “terminate” End Event, the Sub-Process is abnormally terminated. In case of a multi-instance Activity, only the affected instance is terminated.

Terminate End Events only interrupt the specific instance of a given Process level (Process or Sub-Process). Any other parallel instances or higher-level instances are
not affected.

a choreography task is associated with more than two message flows, or with two message flows that are in the same direction (i.e. same sending and receiving participants), then the ordering of the message flows is ambiguous.

If the choreography is ambiguous, and process models associated with each participant in the choreography are independently developed, it may mean that the resulting process models may not be able to interact correctly.

There are a couple of possible solutions:

1) Only permit a choreography task to have a max of two message flows. If two are defined, then they must be in opposite directions.

2) If more than two message flows are defined, then an MEP (and possibly other additional supporting information) needs to be specified that makes the ordering explicit. For example, request/response/fault MEP could be specified, where only one message flow could be in one direction (i.e. the request), and all others are in the opposite direction - and the semantics would be that only one of the 'response' message flows could occur. Note: not sure whether it would be necessary to distinguish those flows as one normal response and remaining being fault responses - may be necessary to map to standard rpc pattern.

Does a CallActivity own data inputs, outputs, etc? And when you draw a data association to/from a CallActivity, is the data association connecting to/from data inputs and outputs of the CallActivity or data inputs and outputs of the CallableElement?

PDF pg 196 states that "Call Activities must not define their own data inputs, InputSets, and outputs, OutputSets but use the data inputs, InputSets, and outputs, OutputSets defined in the referenced CallableElement"

This reads like CallActivities don't own data inputs/outputs of their own.

But then PDF pg 225 states that "... the data inputs and outputs of the Call Activity must match with the data inputs, inputsets and outputs, outputsets defined in the callable element".

This explicitly states that a CallActivity does own data inputs, etc. So then what's the meaning behind the statements on PDF pg 196?

a) in section 10.2.6 Call Activity, replace the following paragrah:
"Since Call Activities rely in the CallableElement being invoked (see Figure 10.40), Call Activities must not define their own data inputs, InputSets, and outputs,
OutputSets but use the data inputs, InputSets, and outputs, OutputSets defined in the referenced CallableElement."
with this one:
"A CallActivity must fullfil the data requirements, as well as return the data produced by the CallableElement being invoked (see Figure 10.40). This means that the
elements contained in the CallActivity's InputOutputSpecification must exactly match the elements containes in the referenced CallableElement. This includes
DataInputs, DataOutputs, InputSets and OutputSets."
b) in section 10.3.1 Data Modeling (Call Activity Mapping) replace the following paragraph:
"Since Call Activities rely in the callable element being invoked, the data inputs and outputs of the Call Activity must match with the data inputs, inputsets and outputs,
outputsets defined in the callable element. The data inputs and outputs of the Call Activity are mapped to the corresponding data inputs and output of the Callable
Element without any explicit data association."

How are correlation key property values pulled from a process instance?
Correlation Property Retrieval Expression only maps the contents of the
message instance to a key instance, not to the process instance.

• Added improved description as part of 14703.
• Correlation key properties are only pulled from a message, on behalf of a process instance (via the associated conversation that the send/receive task or message
  event belongs to), and thus assigned as a key to the process instance. Thus nothing needs to be added.

While tokens may help explain behavior, the specification should not rely on the concept of tokens to define the normative behavior of model elements.

Sequence flows represent temporal constraints requiring that an "incoming" constraint be satisfied before a flow element can be executed. The specification should refer to the sequence of execution or the flow of control rather than the flow of tokens.

While the specification explicitly says that tokens are a theoretical concept for explanation of behavior, the specification refers to the flow of tokens in many places. For example, the end event behavior is described as "The Process will be in a running state until all tokens are consumed."

Since tokens are not required for compliance, the normative definitions of behavior should not be specified in terms of token flows but in terms of satisfaction of temporal constraints.

Consistent use of temporal constraint semantics is importnant for specialization of processes (addition of intervening elements) and analysis of processes such as validation of compliance with a choreography.

The names Call Conversation and Call Choreography are confusing and incorrect. Conversations and Choreographies are not elements that can be "called."
Also the Call Activity may be technically correct, it is a term not oriented for business modelers. It would be best to change the terminology for all elements that "call."

Reason:

• The change will cause a lot of instability in the spec as it touches so much.
• As the CallActivity in Orchestration keeps the term "Call" the spec becomes inconsistent.
• Even if "Call" is a technical term, it seems to be accepted by the BPMN community at least for the Orchestration case. Why should it be inaceptable in the
  Choreagraphy area?

The XML Schemas BPMN20.xsd and Semantic.xsd define lots of global elements. This allows the elements to be used as XML file root. I don't think that this is intended: BPMN 2.0 files should be always rooted with "bpmn:definitions", and only a few elements are allowed as sub elements (including imports, diagrams and all root elements).

The current design would e.g. make a file be a valid BPMN 2.0 file which consists of a single activity only.

Include the following text to chapter 16.2. For details see attachment (use newer version).
Document Structure
A domain-specific set of model elements is interchanged in one or more BPMN files. The root element of each file MUST be <bpmn:definitions>. The set of files must
be self-contained, i.e. all definitions that are used in a file MUST be imported directly or indirectly using the <bpmn:import> element.
Each file must declare a "targetNamespace" which MAY differ between multiple files of one model.
BPMN files MAY import non-BPMN files (such as XSDs and WSDLs) if the contained elements use external definitions.
Example:
main.bpmn
<?xml version="1.0" encoding="UTF-8"?>

In 14.1, process instantiation is described. The possibilities described there are message start events and an event based gateway with out incoming sequence flow. However, on page 139, the receive task is described to be capable to instantiate process instance as well. Also the metamodel describes the "instantiate" attribute for that task.

I suggest to add a paragraph to 14.1 that describes the instantiating behavior of a receive task.

In addition, is it intentional that in "In order for the Task to Instantiate the Process it must meet one of the following conditions" on p139, "Instantiate" is written with a capital I?

Collaborations and Choreographies have a large degree of overlap in underlying capabilities--basically being a collection of Participants and Message Flow. Choreography only adds the sequencing of the Message Flow. It would be useful to be able to take the same interaction model and display it as either a Collaboration or a Choreography. The definition of those views would determine what should be displayed and how they are displayed.
A merger of the two diagrams in the metamodel would greatly simplify the implementation, add flexibility, and improve BPMN support of other specifications, such as SoaML.

On page 180 begins the serialized XML example (table 10.19) of the process model shown in figure 10.23 . The definition of a sequence flow is missing in the serialized XML.

The process model has 11 flows, but in the XML example there are only 10 sequence flows defined. So one is missing.

The missing flow is that one between AND - Join (called "OrderAndShipmentMerge") and the user task "Review order".

Use Case: When using BPMN 2.0 in systems management environments many tasks will be implemented as scripts. Especially, a huge amount of scripts already exist in these environments and BPMN 2.0 should support an easy and straightforward way to allow making use of them as script activity implementations.

Issue: Scripts to be performed must be copied to the already defined @script attribute to make it inline to the script task. In practice, this is not only redundant but also introduces a lot of potential consistency problems because the proper script might be subject to change; in that case, all copies in all script tasks must be found and adapted accordingly.

Prososed resolution: Add a new attribute @scriptRef (of type URI or QName) to the scriptTask element. This allows to point to the script to be executed.

Minor comments: There is no need to introduce the script separately as an operation of some (artificial) interface. This should be clarified.

The script task refers to a NONE task which has been renamed into Abstract Task: needs to be fixed.

How can one address (in an <assignment>, for example) a particular instance of a multi-instance data object, i.e. a data object with attribute isCollection value set to "true"?

It is unclear why the ioSpecification must be defined with isCollection=true to result in multi-instance execution of the task. Why isn't it sufficient to refer (via the dataInputAssociation/sourceRef element) to a multi-instance data object to trigger multi-instance exection of the task. Is the attribute isCollection needed as attribute of dataInput and dataOutput at all? [Multi Instance Tasks controlled by loopDataInput (Section 10.2.8)]

I assume that defining a data object with isCollection=false based on an itemDefinition with isCollection=true is not allowed, correct? But the reverse is allowed as shown in the document. The question is why supporting isCollection as attribute of an item definition at all; supporting isCollection with elements using the item definition would suffice. [Item Definition as multi-instance (Section 8.3.12)]

A corresponding document (BPMN Script invocation.DOCX) with more background has been sent to Tammo van Lessen.

Section 8.3.12 properly describes the behaviour in the case the data object is a collection.

Filed for soaML: It should be possible to link hexagons (conversations /
communications) to activities. This would mean messages flow from
within the activity, which could be calls or subs. The hexagon can be
expanded to show message flow connected to the activity, including calls
and subs.

Conversation links are groupings of message flows, so they can be linked
to activities and events just as message flow can. The resolution
supports conversation links to activities and events, but not message
flow to conversation nodes a requested by the issue. This restriction
is only by textual constraint, if a future RTF would like to loosen it.
Conversation Link is added to the metamodel to simplify implementation
of this resolution. The notation for conversation links is changed to a
double lines, to distinguish them from sequence flows when used with
activities and events. The forked line end notation for conversation
links ("crow's feet") is removed to simplify usage and implementation,
since it is redundant with participant multiplicity notation.
The resolution assumes the resolution of 14654.

Callable elements can be simplified. For example, a Global Choreography Task can be a sub-type of Choreography. It would be defined as an "empty" Choreography. A Global Task could be a sub-type of Process, with the same restriction.
By doing this, then calling elements within the diagram can be more specific about what kind of element they can reference. Thus, a CallActivity can reference a Process and a Call Choreography can reference a Choreography, instead of both referencing Callable Elements with an text based restriction as to what kind of callable element can be referenced.

The XSD schema supports mixed-content text within Documentation or Text Annotations. This allows for formatted content (e.g. html tags for bolding or italics).

The problem occurs when interchanging the XML, since a consumer of the XML has no way of telling what format was used for the text (i.e. to tell that it was html rather than plain text).

You cannot add elements to the subclass without violating the Unique Particle Attribution (UPA) rule in XML Schema (http://www.w3.org/TR/2004/PER-xmlschema-1-20040318/structures.html#non-ambig)

(a) Update tBaseElement and tBaseElementWithMixedContent in the XSD (see Semantic-Snippet.xsd attached to this issue)
(b) Update the XSD snippets (Table 8.17) in the spec

Taking Figure 10.121 as an example, it’s unclear what the outer box represents in the diagram – is it a graphical Pool representing a Participant named Supplier linked to a PartnerEntityRole also named ‘Supplier’ in turn linked to a Process also called Supplier? Or is it merely a Process called Supplier (in which case it could be better named ‘Supply Process’)? I would have thought the latter, but that does not tie in with my reading of 13.2.3 which states that “A Lane is a sub-partition with a Pool” and “A Pool is the graphical representation of a Participant in a Collaboration (see page 146). It is also acts as a graphical container for partitioning a set of Activities from other Pools, usually in the context of B2B situations.” Likewise Figure 13.4 provides only one interpretation – as Lanes within a Pool not within a Process.

Though Table 13.1 states that a Process Diagram has at least one LaneCompartment (which is inconsistent with 13.2.3 which states that Lanes are only within Pools) this is inconsistent with the serialization (in Table 10.19) of Figure 10.23 which has no instance of Lane at all. And Figure 10.23 appears to use the Pool notation shown in Figure 13.3

The CorrelationKey element is currently an abstract element in the metamodel. Since it has no concrete sub-classes, it should made a concrete class

It is not precisely defined what definitions must be made in order to specify that a particular executable is to be invoked as an implementation of an operation of a service task (for example).

The specification should clearly spell out which definition are mandatory in order to capture the major scenarios, e.g. using an operation of WSDL port; using a java class;...

I submitted a document with more details on the problem area to issues@omg.org, without any response since weeks. I am happy to send this document to the person assigned to this issue, and discuss it.

• To "Table 8.80 - Interface attributes and model associations", add the following row:
  implementationRef: Element[0..1] This attribute allows to reference a concrete artifact in the underlying implementation technology representing that interface, such as
  a WSDL porttype.
• To "Table 8.81 - Operation attributes and model associations", add the following row:
  implementationRef: Element[0..1] This attribute allows to reference a concrete artifact in the underlying implementation technology representing that operation, such as
  a WSDL operation.
• Update the UML meta-model and XSD schema accordingly.

Bullet items for Start Event Message Flow Connections refers to the "Trigger" attribute of the Start Event. The name of this attribute was changed to "eventDefinitionRefs."
These items, and other similar uses of the word Trigger, should be corrected.

The statements of those bullets is actually wrong, the trigger attribute do not have a value of "Message" or "Multiple", they are EventDefinition elements. Also they do
not add any value since the connection rules are properly described in Section 7.5.2 Mesage Flow Connection Rules
So the proposed fix is to remove these 2 bullets:
• The Trigger attribute of the Start Event MUST be set to Message or Multiple if there are any incoming Message Flow.
• The Trigger attribute of the Start Event MUST be set to Multiple if there are more than one incoming Message Flow.

Consider a process with a Data Object and a Subprocess. The subprocess has an activity. Can you draw a data association from the data object (in the process) directly to the activity (in the subprocess).

• The introduction of Data Inputs/Outputs for subprocesses implies you should always go through the Data Inputs/Outputs. That is, you must draw the data association from the Data Object to the subprocess Data Input, and then draw another data association from the subprocess Data Input to the Activity inside the subprocess.

• But then page 216 states that the data object is 'visible' to the subprocess and the activity inside the subprocess, which implies the activity can access it directly without necessarily going through the subprocess data input.

So, two different means of doing the same thing, with likely different tools assuming/supporting one or the other or both.

This issue has the same resolution as OMG 14817 (14817)

Data Object is a Flow Element because it can apppear in a Flow Element Container (e.g., a Process). Data Inputs, Data Outputs, and Data Stores should also be Flow Elements for the same reason.
These elements would not need there own name attribute in this case.

Table 10.19, the XML serialization of the Buyer process in figure 10.23 (pg. 150) is shown. The process model in figure 10.23 shows a Pool named Buyer. The metamodell provides the possibility to define pools as participants, which have a reference to the process definition. But Table 10.19 doesn’t contain any definition of a participant.

There is a requirement for the “Exporter” of a BPMN 2 file to be identified. Such identification will allow an importing tool to take various appropriate actions to ensure ease of exchange and interchange of BPMN 2 files (for both semantic and diagrams).

There is substantial practical evidence of the benefits of such information. In fact XMI provides support for such information. You can refer to MOF 2.0/XMI Mapping Specification, v2.1.1, section 4.5.2 and section 4.5. in the XMI spec for description of the <documentation> class, which is part of the XMI model. It contains the nested element <exporter>, and <exporterVersion> which serves this purpose.

The intention is that any model that is an instance of MOF and serialized in XMI is able to include an instance of <documentation> nested in the root. As the example given by Pete shows:

More specifically there is the following in the XMI spec :

<xsd:complexType name="Documentation">

<xsd:element name="exporter" type="xsd:string"/>

<xsd:element name="exporterVersion" type="xsd:string"/>

For example:

<xmi:XMI>

<documentation xmi:type=xmi:Documentation>

<exporter>MagicDraw UML</exporter>

<exporterVersion>16.8 Beta</exporterVersion>

</documentation>

This would require changes to section 8.1 and 8.1.3 of the BPMN 2 spec

Proposal:

Add to the tDefinitions xsd complexType:

<xsd:attribute name="exporter" type="xsd:string" />

<xsd:attribute name="exporterVersion" type="xsd:string"/>

This will give two new optional properties (exporter and exporterVersion).

(a) Add to the tDefinitions xsd complexType:
"<xsd:attribute name="exporter" type="xsd:string" />
<xsd:attribute name="exporterVersion" type="xsd:string"/>"
(b) Update Figure 8.4, Figure 8.5, and Figure 8.6 to reflect this change
(c) Update Table 8.1 and Table 8.3 to include these attributes

In the current semantics description of the inclusive gateway:

The Inclusive Gateway is activated if
• At least one incoming sequence flow has at least one Token and
• for each empty incoming sequence flow, there is no Token in the
graph anywhere upstream of this sequence flow, i.e., there is no
directed path (formed by Sequence Flow) from a Token to this
sequence flow unless

• the path visits the inclusive gateway or
• the path visits a node that has a directed path to a non-empty
  incoming sequence flow of the inclusive gateway.

it does not get clear that the latter path is also not allowed to visit the inclusive gateway.

I suggest to reword the entire sentence.

The same applies to the semantics of the complex gateway.

Table 14.3, first row, second column: replace the contents of the column with the following:
"The Inclusive Gateway is activated if
1. At least one incoming sequence flow of the inclusive gateway has at least one Token and
2. for every directed path formed by sequence flow that
i. starts with a sequence flow f of the diagram that has a Token,
ii. ends with an incoming sequence flow of the inclusive gateway that has no Token, and
iii. does not visit the inclusive gateway,
there is also a directed path formed by sequence flow that
iv. starts with f,
v. ends with an incoming sequence flow of the inclusive gateway that has a Token, and
vi. does not visit the inclusive gateway.
If the inclusive gateway is contained in a sub-process, then no paths are considered that cross the boundary of that sub-process.
Upon execution, a Token is consumed from each incoming sequence flow that has a Token. A Token will be produced on some of the outgoing sequence flows.
In order to determine the outgoing sequence flows that receive a Token, all conditions on the outgoing sequence flows are evaluated. The evaluation does not have to
respect a certain order.
For every condition, which evaluates to true, a Token must be passed on the respective sequence flow.
If and only if none of the conditions evaluates to true, the Token is passed on the default sequence flow.
In case all conditions evaluate to false and a default flow has not been specified, the inclusive gateway throws an exception."

Figure 12.4; The Choreography model is not locally enforcable.

In the last interaction the Supplier doesn't participate in the previous interaction.

But in chapter 12.4.6 on page 328 (358) it is said: "The Initiator of a Choreography Activity MUST have been involved (as Initiator or Receiver) in the
previous Choreography Activity."

The lane in the middle of the Collaboration model (Figure 12.3 page 311 (341)) has a wrong name. It should be Supplier not Shipper.

(a) Update the Collaboration model, renaming the name of the lane in the middle of the model into "Supplier".
Figure 12.3 page 311 (341)

(b) Update the Choreography, changing the order of the last interactions. Put the fourth from last interaction "Accept PO and
Delivery Schedule" right behind the last interaction "Finalized PO and Delivery Schedule".
Figure 12.4 page 312 (342)

(c) Update the Collaboration model, changing the position of the interaction between the Retailer and the Supplier about the message "PO & Delivery Schedule". Put the Send Message Task in the lane "Retailer" right behind the last Recieve Message Task in that lane.
Figure 12.3 page 311 (341)

(d) Update the last sentence in the paragraph under the Collaboration model. Exchange the 2 words "Retailer" and "Supplier". The sentence should look like this: "´accordingly, the
Retailer interacts with the Consignee and Supplier for final confirmations."
