Definition |
| Sampling |
Using a smaller group to represent the whole; foundation of statistics which can save time, money, and effort; allows for more meaningful data; can improve accuracy of measurement system. |
| Sampling bias |
When data can be prejudiced in one way or another and do not represent the whole. |
| Scatter plot or diagram |
Graph used to show relationship-or correlation-between two factors or variables. See also Correlation Coefficient. |
| Scope |
Defines the boundaries of the process or the Process Improvement project; clarifies specifically where opportunities for improvement reside (start- and end-points); defines where and what to measure and analyze; needs to be within the sphere of influence and control of the team working on the project-the broader the scope, the more complex and time-consuming the Process Improvement efforts will be. |
| Should-be process mapping |
Process-mapping approach showing the design of a process the way it should be (e.g., without non-value-adding activities; with streamlined workflow and new solutions incorporated). Thus contrasts with the "As-Is" form of process mapping. See also Process Redesign, Value- Adding Activities; Non-Value-Adding Activities. |
| SIPOC |
Acronym for Suppliers, Inputs, Process, Outputs, and Customer; enables an "at-a-glance," high-level view of a process. |
| |
|
| Six Sigma or 6 Sigma |
1. Level of process performance equivalent to producing only 3.4defects for every one million opportunities or operations. 2. Term used to describe Process Improvement initiatives using sigma-based process measures and/or striving for Six Sigma-level performance. |
| Solution statement |
A clear description of the proposed solution(s); used to evaluate and select the best solution to implement. |
| SPC |
Statistical Process Control is use of data gathering and analysis to monitor processes, identify performance issues, and determine variability/ capability. See also Run Charts; Control Charts. |
| Special cause |
Instance or event that impacts processes only under "special" circumstances -i.e., not part of the normal, daily operation of the process. See Common Cause; Variation. |
| Sponsor (or Champion) |
Person who represents team issues to senior management; gives final approval on team recommendations and supports those efforts with the Quality Council; facilitates obtaining of team resources as needed; helps Black Belt and team overcome obstacles; acts as a mentor for the Black Belt |
| Storyboard |
A pictorial display of all the components in the DMAIC process, used by the team to arrive at a solution; used in presentations to Sponsor, senior management, and others. |
| Stratification |
Looking at data in multiple layers of information such as what (types, complaints, etc.), when (month, day, year, etc.), where (region, city, state, etc.), and who (department, individual). |
| Stratified sampling |
Dividing the larger population into subgroups, then taking your sample from each subgroup. |
| Supplier |
Any person or organization that feeds inputs (products, services, or information) into the process; in a service organization, many times the customer is also the supplier. |
| Systematic sampling |
Sampling method in which elements are selected from the population at a uniform interval (e.g., every half-hour, every twentieth item); this is recommended for many Six Sigma measurement activities. |
