SIPOC – An Amazing Way to Reduce Waste and Streamline Workload

SIPOC – An Amazing Way to Reduce Waste and Streamline Workload | Six Sigma (Coffre d'outils) | Scoop.it

The SIPOC chart, is simple and easy to use for employees at any level. It promotes better job understanding, then provides a means to streamline workload, increase efficiencies and reduce waste.

 

Every employee can think of his/her job as a “Process”.

 

Every “Process” is linked to Suppliers / Inputs and to Customers / Outputs.

 

The SIPOC chart breaks down each of these elements into a separate buckets, so employees can better clarify their role and linkages to others.

Documentation for the Project Initiation Process – Part 8

Documentation for the Project Initiation Process – Part 8 | Six Sigma (Coffre d'outils) | Scoop.it

The scope statement and the statement of work, or SOW.

 

Scope statement :

 

It provides a single-statement, single-paragraph, or single-page overview of the project and its boundaries. It describes the project in clear objective terms, highlighting the outcomes and any deliverables associated with the effort. If there is a significant probability of misunderstanding, the scope statement is used to refine what is not included as part of the project, as well…meaning, “it does not include this, etc….”.

 

Statement of work :

 

The statement of work (SOW) serves as a guideline of the agreements on performance between a purchasing organization and a seller of goods and/or services. It is frequently an attachment to a contract or a memorandum of understanding between two organizations, but it may also be its own stand-alone document. The SOW affirms how the purchasing organization wants the work to be performed and the context of that performance, including any specific management practices or protocols the contractor must follow.

DMAIC | Six Sigma (Coffre d'outils) | Scoop.it

DMAIC is a five-step data driven quality improvement approach. The five steps in DMAIC process are:

 

1. Define

2. Measure

3. Analyze

4. Improve

5. Control

 

DMAIC is a disciplined quality management approach which uses tools and data for making informed decisions.

Process Capability Statistics: Cpk vs. Ppk

The goal of capability analysis is to ensure that a process is capable of meeting customer specifications, and we use capability statistics such as Cpk and Ppk to make that assessment.

 

Cpk:

 

_ Only accounts for the variation WITHIN the subgroups

_ Does not account for the shift and drift between subgroups

_ Is sometimes referred to as the potential capability because it represents the potential your process has at producing parts within spec, presuming there is no variation between subgroups (i.e. over time)

 

Ppk:

 

_ Accounts for the OVERALL variation of all measurements taken

_ Theoretically includes both the variation within subgroups and also the shift and drift between them.

Accuracy vs. Precision: What’s the Difference?

Accuracy vs. Precision: What’s the Difference? | Six Sigma (Coffre d'outils) | Scoop.it

What types of measurement system errors may be taking place ?

 

Here’s where accuracy and precision come into play.

 

Accuracy refers to how close measurements are to the "true" value, while precision refers to how close measurements are to each other.

 

In other words, accuracy describes the difference between the measurement and the part’s actual value, while precision describes the variation you see when you measure the same part repeatedly with the same device.

Hocus POCIS: The Magic of the SIPOC Diagram

The SIPOC (suppliers, inputs, process, outputs, customers) process map is one of the most valuable tools in a Six Sigma professional’s toolbox.

 

It typically can be completed with the project team in less than an hour, and has a strong tie to the project charter. It also makes previously unknown customers suddenly appear out of thin air.

 

The SIPOC provides an end-to-end picture of a process and is the linchpin of the Define phase of any DMAIC (Define, Measure, Analyze, Improve, Control) project.

Comment effectuer les mesures ?

Comment effectuer les mesures ? | Six Sigma (Coffre d'outils) | Scoop.it

Six Sigma est une méthode de résolution de problème en 5 étapes (DMAIC), orientée client et fondée sur des données statistiques.

 

La deuxième étape est la phase “MEASURE”.

 

Elle comprend :

 

1. La cartographie des processus

2. Les mesures systèmes : les extractions de données historiques

3. Les mesures terrain : les mesures effectuées sur le terrain par observation.

Project Selection That Benefits the Entire Business

Project Selection That Benefits the Entire Business | Six Sigma (Coffre d'outils) | Scoop.it

Practitioners of process improvement strive to determine what can be done to improve areas of the business they have been assigned to investigate; however, often these efforts take place in silos where such improvements are not felt by executives who are examining the enterprise as a whole. Further, the management of an organization is not typically viewed as a process with its associated improvement opportunities.

 

These nine steps provide a systematic approach to improving the enterprise system as a whole and how it is managed.

SIPOC Diagram

SIPOC Diagram | Six Sigma (Coffre d'outils) | Scoop.it

SIPOC stands for Supplier, Input, Process, Output, Customer.

 

The SIPOC is usually presented in the form of a straightforward diagram, which will be referred to during the Define and Measurement stages of DMAIC.

 

Coming up with the SIPOC diagram is usually a collaborative effort, focusing on brainstorming and refining the results.

 

Creating a SIPOC diagram begins with a sub-diagram for the process. keep it simple with no more than 5 high level steps, and no more than two or three words to describe each step.

 

Next, think of the inputs that are needed for the process (including triggers, tools, data and systems) and any supplier needed to provide these inputs.

 

The outputs of this process should then be identified, along with the customers who receive those outputs.

 

At this stage, it can be useful to document customer requirements.
