What is the difference between Policy, Process and Procedures?
A Policy is essentially a set of basic principles and associated guidelines, formulated and enforced by the organization typically designed to demonstrate compliance with a regulatory obligation and in so doing demonstrate objectives and actions in pursuit of long-term goals.
A Process is typically understood to be a sequence of usually separate but linked procedures and which, also requires a number of resources to achieve.
Procedures provide instructions or guidance ideally in clear, non-ambiguous, and effective manner describing in “simple language” to how a particular task or activity should be accomplished.

Procedures should always be written with the needs of the user in “sharp focus”. It is a mistake to write the procedure in the context of your particular understanding. When writing procedures we should use “action language”. All procedures should include a high-level explanation of the procedure, together with a statement of the reason for the procedure, and information which identifies the applicability of the procedure.

Procedures also need to be formulated in a step or sequence approach which may be easily understood by the user of the procedure.
Terms which are used in the procedure must be understood so any abbreviations should be clearly identified at least during the first use of each procedure within a given document.
Flowcharts can provide support for procedures by helping the writer to create the procedure or may if relevant be included within the procedure to provide a graphically representation of the particular element of the process.
- Oval terminal symbol = Contains the beginning or end of a process
- Rectangle process symbol = Contains a step or action
- Diamond decision symbol = Contains a decision point (e.g., yes, no)
- Parallelogram input/output symbol = Any Relevant Data required or available
- Rounded Rectangle = Delay or Deliberate Wait for action
- Line with arrow = Identifies the process direction (or Bi Directional)
- Small Circle = Link to another part of the flowchart or another page
It is important to deliver consistency throughout the procedure and for this to happen we should establish “Document Standard Guidelines”.
With an understanding of document standard guidelines we will identify the format of our manual or document, to include a system of numbering and identifying the sections and chapters.
In addition we may choose to develop suitable templates to ensure that all elements of or procedure are clearly identified and included in the document.
A Standard Font should be utilized throughout the document together with the use of numbering system and where to use Bolding etc.

Aircraft Production Planning belongs to the Maintenance Organisation and is related to the size of the organisation, from a very humble structure to an intensive business management process.
There is much opportunity available within the Production Planning business area to deliver savings and the challenge is to identify efficient business processes that can be used to gather the data, analyze and measure the opportunities and finally to act on this.

This Training introduces the delegate to the basics of the EASA 145 Production Planning Process and considers the elements which are involved to deliver an effective Production Planning System.
