Processes requiring this procedure

The procedure is required to carry out quality control process.

Purpose

It ensures that nonconformity in each laboratory process is identified, controlled, corrected and prevented, therby reducing need for risk management.

Scope

All laboratory processes come under the scope of this procedure

Policy of Risk Management

Users of the procedure

Any personnel of the laboratory involved with any process need to use this procedure.

Procedure

Step 0: Imagine (Risk management)

  • Risk is a potential NC. It has two components.
    • Amount of effect on quality objectives
    • Probability of its occurrence in current state of the laboratory
  • For various processes identify risks.
  • Put it under appropriate risk matrix as shown in table below

Effects
0=Not much effect on quality objectives
10=Major effects on quality objectives
Probability
0=unlikely
10=Very likely
  • Act to prevent highly probable risk with major effects on the quality objectives
  • Develop plan to control and correct moderately probable risk with moderate effects on the quality objectives
  • Accept less probable risk with minor effects on the quality objectives

Step 1: Identify

Any personnel can identify nonconformity
The person is called First information personnel

Common(but not the only) sources of identifying nonconformity
internal quality control
interlaboratory comparisons
internal audit
external audit
feedback from laboratory personnel and users of the laboratory
instrument calibrations
checking of consumable materials
reporting and certificate checking
laboratory management reviews

Step 2: Inform

each nonconformity is informed to authorized signatory who is responsible for coordinating step-3.

Step 3: Take Actions

Authorized signatory, if required with help of other personnel, notes down properties of nonconformity; plans, implements, reviews and records actions as follows.
