What is a Statistical Technique!

A method to collect, analyze and interpret data relating to product and process performance. This will help to ensure consistent quality, and appropriate process controls. It is also used to promote continuous improvement. It applies to data gathered from process, shipment, inspections and marketing analysis.

You will need to establish measures for determining if a sample size is truly representative of a given population with respect to the data being collected and analyzed. An adequate sample size is necessary in order to ensure compliance with the production requirements of your company’s operation.

Random Sampling is performed on a given set of activities, in order to provide a cross sectional overview of a set of activities being looked at. Answers to these, and a lot of other questions can be found in ANSI/ASQC Z1.4, Sampling Procedures and Tables for Inspection by Attributes. 

Do you have such a procedure?  If not, you may want to create one.  Before getting started, you will need to consider and address the following steps:

1.      Determine the need for Random Sampling.
2.      Coordinate what needs a Sample Inspection.
3.      Define the appropriate Inspection Criteria.
4.      Develop, Approve and Implement a Statistical Technique Procedure.

Sampling Plans may be Single, Double or Multiple. Inspection Levels I, II or III would need to be determined. You will start out performing Normal Inspections. Should the number of lots accepted increase or decrease; you will change to Reduced or Tightened Inspections, as applicable. Lot or batch sizes vary, depending on the total number.

If you do not have a documented statistical technique program, consider utilizing an audit consultant to assist your team, or perform this for you, so that you can focus on what’s most important to you - your customers.

Why You Need a Documented Back Office Process

Are your work days getting longer? Going to work earlier and staying later to get everything done. Still not enough hours in the day! Don’t assume your employees know what you expect of them. Do you have a documented Back Office Process? Did things work out ok in the past? Are they ineffective today?

You will need to step back and perform an independent assessment of what you have, or do not have in place, to find out what the problems are. First start out by asking your employees. If you want to improve operations, and increase overall efficiencies, who better to ask than the people that do this work day in and day out. Some of the areas you will need to evaluate are:

   1.  Accounts Receivable
   2.  Accounts Payable
   3.  Bid Quotation, Preparation, Review and Approval
   4.  Employee Qualification
   5.  Equipment Maintenance
   6.  Expense Reporting
   7.  Marketing and Solicitation
   8.  Payroll
   9.  Record Keeping
  10. Work Scheduling

This will help to identify opportunities where you can make changes that will help to reduce workload, and raise employee moral. If you do not have one, consider utilizing a consultant to assist your team, or perform this for you, so that you can focus on what’s most important to you - your customers.
