PROCESS IS THE MAIN THING

ADD TO BOOKMARKS: BPMNTRAINING.RU/NEWS

For those who miss posts on this blog: for certain reasons now I publish more at
bpmntraining.ru.

For the convinience of my English-speaking readers I’ll translate the most
popular posts here, like this one.

HOW TO DEPICT SOFTWARE INTERNALS IN BPMN

This post was originally published at bpmntraining.ru.

Typical BPMN use cases are:

1. create a process-based operations manual (let’s call this “analogue” process
modeling)
2. create a BPMS-executable model (let’s call this “digital” process modeling)
3. create process-based software requirements for application developers

Let’s define the analogue/digital divide first and then proceed to use case #3.

MESSAGE, SIGNAL OR CONDITIONAL?

Bruce Silver shared his thoughts about the conditional event in the recent post.

For those not deeply immersed into BPMN 2.0, the conditional event pauses a
process until specified logical expression becomes true (changes its value from
false to true, to be precise). I’m writing this post in October, so the good
conditional start example would be:

Fig. 1. Conditional start event example.

Here the process starts when the logical expression becomes true, i.e. when
winter comes. (BTW, this is the real rule in effect here in Moscow.)

The typical conditional intermediate example:

Fig. 2. Conditional intermediate event example.

Here the process waits until the invoice record stored in some unspecified
system would be marked as paid. (This is overly simplistic version - please be
patient, the more robust will follow.)

Bruce says that he prefers not to use conditional events and excluded it from
the “Method and Style” - the collection of best practices he created, supports
and promotes by his famous book (the best BPMN guide in my opinion).

With all respect to Bruce as my BPMN teacher, I have a different opinion on the
matter: I believe that conditional event is the best solution for certain quite
common process collaboration scenarios. (To be more specific, it’s the
conditional intermediate event; the conditional start event doesn’t have much
value so it won’t be discussed here.) » read the rest

BPMN NONE INTERMEDIATE - THROW OR CATCH?

The BPMN 2.0.2 specification is ambiguous regarding the subject.

Please compare:

1) Table 10.89 at p. 250 says:

The None Intermediate Event is only valid in normal flow, i.e., it MAY NOT be
used on the boundary of an Activity. Although there is no specific trigger for
this Event, it is defined as throw Event. It is used for modeling methodologies
that use Events to indicate some change of state in the Process.

2) Table 10.93 at p. 259 also clearly shows that None intermediate is a Throw
event.

3) However the text at p. 271 says the opposite:

There are three (3) variations of None Events: a Start Event, a catch
Intermediate Event, and an End Event

Here is what other authoritative sources say -

4) Bruce Silver, “BPMN Method & Style”:

Omission of eventDefinition signifies a throwing None event, which is allowed;
it can be used in the diagram to indicate a particular state of the instance.

5) Tibco:

Intermediate None event indicates an unspecified change in the process.

6) Camunda:

Intermediate none events (throwing) can be used to indicate some state achieved
in the process.

Looks like the text at p.271 should be corrected to -

There are three (3) variations of None Events: a Start Event, a throw
Intermediate Event, and an End Event

PS. Thanks to my colleague Julia Wagner for pointing to this issue.

UPDATE: Bruce Silver’s comment -

Anatoly, Yes I agree with your post - (3) is incorrect, along with 400 other
errors reported since 2009.

INTERPROCESS COLLABORATION USING CONDITIONAL EVENT

I wrote here already that it’s common for what business considers a business
process to become several process pools in BPMN - look at process patterns
“internal order” or “incoming processor”. In both examples the “client” process
posts a task into DB and process to wait message from the “server” process that
the task is completed.

The diagrams are valid but here is the caveat: server should know the client
internals - namely the event on the client side. It’s ok if the server deals
with a single client but what if not?

WHY BPM LAGS BEHIND

This is yet another attempt to answer the damned question about BPM: why, albeit
being successful in so many projects, it never matched the analysts’ growth
predictions and still haven’t become mainstream?

There must be something wrong deep in the core. It can’t be just prospects’
ignorance, non-perfect software products or greedy consultants. Nobody would say
that BPM methodology is inadequate or unusable (well, except ACM proponents but
their voices aren’t loud nowadays).

I blogged on the matter already… well, it was 8 years away: 10 Reasons Why BPM
Market Doesn’t Meet The Expectations. It wasn’t a final explanation obviously -
10 answers means one doesn’t have the killing answer.

What turned me back to the matter is a thought that I’ve read recently. It was
about the real value delivered by a good business consultant. It’s not a
specific business receipt or advice; ultimately, it’s about making complex
business issues simple.

Now what do we BPM professionals offer in this respect, do we simplify business
issues? I’m afraid not.

BPM software isn’t an issue here (IT people love complex toys) but we proudly
bring a full-blown discipline, we suggest extensive training programs and
introduce new roles to the organization. We create process diagrams. They turned
out to be rather complex but we rightfully assure that they are as complex as
business is - no more, no less.

This is all true, but… does it make a customer happy? Well, it does - those who
are paranoid to do more with less, be more efficient today than yesterday etc.
Are they majority of business leaders? I don’t know the big picture but for the
selection that I observe the answer is negative.

And what is decision maker’s best alternative? Sweeping garbage under the
carpet: keep it as-is, more or less. Imitate a BPM initative by purchasing BPMS
software is OK but pulling out business processes from employee’s brains and
making them explicit is way too hard, creates too much tension on the way and
too much complexity at the end.

Indeed, implicit processes have numerous hidden weak points and hence are less
effective, less efficient and way less agile… but who cares, as soon as the
majority of organizations around operate this way. See no evil, hear no evil.
Not that efficient but simple and manageable from C-level perspective.

Current Digital Transformation trend should break this modus operandi because
digital business models implies digital business processes. So hiding processes
complexity by delegating them to performers shouldn’t be an option any more.

MORE ON ESSENTIAL AND REDUNDANT BPMN: EVENTS

Last time we found out that only two of five BPMN gateways are absolutely
necessary: XOR and AND.

Now let’s consider events. BPMN events are categorized by type (13 variants) and
position (8 variants). Let’s consider event types:

1. None

THE THIN LAYER CALLED PROCESS

It’s a paradox but the term “process” remains the most ambiguous in BPMN, as the
recent discussion on the BPM.com forum has shown.

* In our day-to-day life we call “process” almost anything from digestion to
the formation of galaxies.
* Many consultants are comfortable with the process definitions that cover any
orderly set of activites aimed at certain result. It makes sense when we
focus on business performance but when we get into details it becomes hard to
ignore the difference e.g. between processes and projects. One may treat a
project as special case of a process indeed but the fact is that we manage
projects and processes substantially differently so a definition that makes
no difference between processes and projects would be counter-productive.
That’s why I like the term “business capability” - it provides an umbrella
term for different kinds of business activities yet it doesn’t merge them all
into “process” treated too widely.
* Process definition narrows even more in BPMN context. First, there is a clear
difference between a process and subprocess in BPMN: the former is triggered
by external event (e.g. a message, timer or free will of process initiator)
while the latter is called from overarching process or subprocess. Secondly,
the entities more abstract than a single process are beyond BPMN scope
completely. There is no element to model process groups in BPMN so one can’t
depict things like “value chain”, “supporing processes” or “product
promotion”.

Thus, if we look at the process hierarchy through the prism of BPMN, we’d find
several levels of process groups at the top, several levels of subprocesses at
the bottom and a thin layer of what BPMN calls a process in the middle:
