Value Stream Mapping goes ARIS

A couple of days ago, my colleague Eva Klein has given you an introduction into Lean Six Sigma and related modeling activities. Her post showed that modeling flow charts is not only a core BPM-discipline but is widely acknowledged by lean management practices as well.



I have just returned from a value stream mapping workshop on a customer‘s site in the discrete manufacturing sector. We spend three days in the shop floor walking along the actual pathways of material and information flows ourselves and gathering information each process. While we began with rough sketches by hand in pencil right on the shop floor, ARIS was the tool to document the full-fledged value streams electronically. Being very impressed by the power VSM modelling adds on lean process improvement, I decided to share the basics of value stream mapping in ARIS with you.



What is Value Stream Mapping? And, what is a value stream?



Value stream mapping is an essential tool of lean manufacturing that allows for documenting production processes and analyzing them according to lean management practices. A value stream is an end-to-end process that includes all flows of material and information as a product makes its way from raw material into the arms of customers. VSM is typically used in lean manufacturing (production flow), but also apply to product development (design flow), logistics, supply chain, service-related industries, health care and software development.



How does ARIS support VSM?

 

(1) VSM as ARIS model type

Choose VSM as a process modell type in the Model Wizard

ARIS Six Sigma comes with an additional modeling type for value stream maps. You may either choose to use a VSM as a stand-alone model or use it as part of your process architecture linked to other process models of any kind (e.g. EPC, VAC, SIPOC) via assignments, process interfaces, or occurrence copies.

 

 

 

 

(2) Full range of VSM symbols – well-integrated into the ARIS method

 

In its core a value stream map consists of process boxes, external suppliers and customers and arrows indicating the flow of material and information. In ARIS, they are represented by standard VSM symbols while their object types are ARIS generic. For example, the supplier initiating the flow of material is visualized by the symbol “outside source” which again is of the object type “organizational unit”. This allows you to reuse modeling objects among VSM and non-VSM models.

Beyond the basic elements, ARIS provides you with a variety of push- and pull-connections (e.g. FIFO, Supermarkets, Kanban,…) between process flows. They are the key instrument of the constant quest for waste reduction in lean manufacturing.

 

 

 



(3) Maintaining process times and inventories

Value stream mapping is not only about flow structures but also about gathering process data such as times, inventories, etc. ARIS provides you with VSM attributes that can be maintained per modeling object and placed as text boxes in the model.

 

 

 

(4) Calculating timelines automatically

Based on the data collected and maintained, a value stream map is complemented by a timeline. It shows the value-adding processing times (i.e. when the product is actually processed according to customer requirements) of the process boxes as well as the non-value-adding lead times (i.e. when the product accumulates, waits for the next stop, is transported) in between. ARIS draws this timeline by the means of a macro and calculates the final value added ratio (VAR) between overall lead time and value-adding processing time.



 

 

 

 

 

 

 

 

(5)Evaluating VSMs through specific reports



Additional VSM analysis on overall process efficiency, kaizen bursts, etc. can be performed via specific VSM ARIS reports.

 

 

What’s in it for you?



In a nut shell, value stream mapping in ARIS helps you

  • visualize the flow of material and information in your shop floor
  • see the sources of waste in your value stream and envision a less wasteful future state
  • talk about and discuss manufacturing processes in a common language
  • tie together lean concepts and techniques with BPM
  • bring your BPM experts and your Lean experts on a table
  • create a blueprint for lean implementation

Stay tuned for more project experiences with VSM!

Katrina,

Do you have a quick guide to modeling vsm's in ARIS?  Specifically which attributes are required, where.  I struggled to find all of the attributes required to get the timeline macro to work. 

It would be nice if there were a filter which focused on the VSM/Six Sigma related attributes.  Barring this, how about a report for data collection and lists all of the relevant attributes?

 

thanks

donald dillon

Dillon,

thanks for your question. There is a nice entry in the help menu that should provide you with the answers:

We will certainly consider providing a filter that eases the use of VSM modeling.

Regards

Katrina

Katrina,

That is helpful.  Maybe it can be linked to the VSM information in the Method Help section.

thanks

Katrina,

Can you explain the difference in the attributes 'Working time" and 'Processing time'?  If I want to simulate my process do I need to maintain the same info in 2 different attributes?

thanks

donald

Dear Katrina,

ARIS Business Architect comes with a demo database “United Motors Group”.

Is there a Value Stream Model already included?

I could imagine that the virtual demo company UMG leverages already the VSM methodology for its car production processes.

Please share that example with us or let us know when it will become available.

Cheers

Rune

Donald,

"working time" refers to the net working hours (or minutes/seconds) of the operator or resource at this process, i.e. the uptime available

vs.

"processing time" refers to the time it actually takes to perform this process once

For calculating the timeline, you need both.

Cheers

Katrina

Hi Rune,

you are absolutely right: UMG is the perfect lean company!

We will show how they do the value stream mapping for the production line with the next update of the UMG.

I will post it once it is available!

 

Cheers

Katrina

Katrina,

I am getting results reflecting 'Infinity Day(s)' for process Lead time when I run the timeline macro.  Any idea which attribute I am missing?

thanks

donald

Hi Katrina,

In the list of processes, I am not able to find "Value Stream Mapping". The last in the list is VACD. Is this a limitation of the license that I have? Or do I need to install any component for Six Sigma?

Regards

Sandeep

Hi,

yes, Value Stream Map is an integral part of ARIS Six Sigma. Therefore you need to have the corresponding licence key.

Best regards,

Katrina

Katrina,

What's the actual timeline calculation method? When I try a simple push stream, I have the lead and value-added time correct but the value-added ratio not. When I divide the value-added time by the lead time I get 0.15% while the macro returns 0.00%.

My second question is about the attribute type names. It seems there are some differences in the terms used in ARIS VSM method. For example in ARIS 'customer demand rate' is used for 'takt time'. Actually in this case I like ARIS terminology better (it should be helpful to know the units, I assume seconds but..). But in other cases it get confusing. Is there a glossary or do you plan some kind of documentation?

Regards

Ivo

Katrina,

What is the advantage of using the ARIS Six Sigma Components vs. the standard ARIS EPC business objects?

Bill,

it is not so much about Six Sigma modeling vs. ARIS EPC modeling. Both modeling types rserve their own purposes and ather complement each other. While EPC remains to be first choice for process flow documentation in the context of BPM or BPA, VSM focuses more on material and information flow and is mostly used within Lean projects.

Many organizations appreciate the fact that ARIS offers both and therefore allows to integrate BPM projects with Lean projects. Both, BPM and Lean experts can use the same tool, work on the same repository and even connect their EPC and VSM models by using assignments or by reusing objects.

Best regards

Katrina

Hello, All.

This site is very helpful. 

My goal is to become an expert in using ARIS to document the results of value stream mapping exercises. 

Any help or examples would be greatly appreciated. 

Thank you.

Hi Christine

In order to be able to give you an appropriate answer I need to know in which format you wish to document the relevant information and what details are to be contained in the output. Could you please specify this for me?

Regards

Eva

Hello, Eva,

Thank you for your quick reply.

I am not sure what you mean by format but I am interested in creating models similar to what is referenced in Katrina's response to Dillon on 2010/04/26.

I also wonder if it is possible to add icons?  Examples, inventory that is usually shown as a triangle with an "i" in the middle and a truck to show transportation.

I look forward to your response as well as from others who have used the VSM model in ARIS. 

Thank you.

Christine

Can anyone please help me in identifying as to how does ARIS calculates Customer Demand rate?

I have input Workdays as 1 and hours as 8.

It is automatically taking customer demand rate as 510

 

Can you please guide me in these calculations?

 

Thanks,

Nikhil

Can anyone please help me in solving a VSM map with a parallel flow?

I have mapped the process with parallel flow, however it gives NaN in the timeline calculations.

Does it need anything more to be input before I run the macro?

Hi Nikhil,

unfortunately, the timeline macro does not support parallel process flows.

Hello Eva,

Thank you for your response.

However, can you please let me know How can we tackle this situation? Do we have any alternate solution?

Because I have many flows with parallel structures in them

 

Thanks,

Nikhil

Hi

We have a client who requested value stream mapping in swim lanes.  Please advise as I don't see this option in ARIS.  Also client wants to take a business process model and map it into a high level value stream map.  As far as I can see A value stream is an end-to-end process that includes all flows of material and information as a product makes its way from raw material into the arms of customers. Any additional details on value stream mapping will be appreciate

 

Regards

Marlene

Hi, 

is your VSM tool can fetch data from ERP and other data base and give distribution of machine center wise distribution of process time for different products and inventory before and after each machine center at sku level?
