SOLUTIONS GUARANTEE A+
✔✔Exponential Smoothing - ✔✔Is another form of weighted moving average. It is a
procedure for continually revising an estimate to include more recent data. The method
is based on averaging (smoothing) past values.
✔✔Mean Squared Error - ✔✔is the average of all the squared errors. The differences
are squared and added together, and then that total is divided by the number of
observations.
✔✔Perpetual Inventory System - ✔✔continuously monitors inventory levels. Under such
a system, inventory transactions are recorded as they occur.
✔✔Periodic Inventory System - ✔✔When a company does not know the level of
inventory or the supplier will only deliver at a specific interval such as monthly or
weekly.
✔✔ABC Analysis - ✔✔has been developed to determine which inventory items should
receive the highest level of control
✔✔Economic Order Quantity - ✔✔concerned primarily with the cost of ordering and the
cost of holding inventory, but the basic model can be expanded to address several
issues.
✔✔Economic Production Quantity - ✔✔helps companies control the cost of ordering,
receiving, and holding inventory. allows for incremental ordering and depletion.
commonly used for production processes where inventory is arriving into storage and
sent out into a production process.
✔✔Forward Vertical Integration - ✔✔a company can own the distribution systems and
retail outlets that sell their products;
✔✔Agile Supply Chain - ✔✔focus on quickly getting innovative products to market.
✔✔Vendor Managed Inventory - ✔✔the vendor, or supplier, can better coordinate its
own production with the replenishment of supplier inventory, thus reducing costs and
improving delivery performance between the supplier and the retailer.
✔✔MRP - ✔✔deals with getting the right amount of raw material to the right place at the
right time to support production.
✔✔MRPII - ✔✔initiates the idea of extending the value stream all the way through the
manufacturing and shipping processes. That extension brings production planning,
, machine capacity scheduling, demand forecasting and analysis and quality tracking
tools into the mix. also features tools for tracking employee attendance, labor
contribution and productivity.
✔✔Fishbone Charts - ✔✔how the impact of various inputs into the result of a process.
They help organizations isolate the root causes of problems such as bottlenecks in their
processes.
✔✔Check Sheets - ✔✔are the means used to record data points in real-time at the site
where the data is generated.
✔✔Histogram (box chart) - ✔✔will demonstrate the frequency of data observations
within a preset range of values.
✔✔Pareto Chart - ✔✔represents data values in a descending order to visualize the
most frequent occurrences.
✔✔Control Charts - ✔✔are graphical depictions of process output where the raw data is
plotted in real-time within upper (UCL) and lower control limits (LCL).
✔✔Run Charts - ✔✔are another form of control chart for processes that might have
common features, a common scale, or some form of central tendency.
✔✔Define - ✔✔The Six Sigma expert uses a project charter to define a problem or
improvement opportunity.
✔✔SIPOC Chart - ✔✔defines the Supplier-Input-Process-Output-Customer
relationships in a process.
✔✔Measure - ✔✔process performance is accomplished with a process map of the
activities performed at each step of the process. Each step is assessed to determine the
ability to meet customer specification in a capability analysis.
✔✔Analyze - ✔✔Charts and diagrams are used to visualize the measurements and the
frequency of problems or defects, including scatter plots, pareto charts, histograms, and
run charts. The main objective of the Analysis phase is to determine the root causes of
variation in the process that result in failures or defects.
✔✔Improve - ✔✔The current process is changed by addressing the root causes
identified in the Analysis stage to improve process performance.
✔✔Control - ✔✔Maintaining and standardizing the improved performance is the final
step of the DMAIC methodology. This can be accomplished through a control plan to
document the requirements to reduce process variation.
