Pharmacy is the health profession that links the health sciences with the chemical sciences and it is charged with ensuring the safe and effective use of pharmaceutical drugs. The word derives from the Greek: φάρμακον (pharmakon), meaning "drug" or "medicine" (the earliest form of the word is the Mycenaean Greek pa-ma-ko, attested in Linear B syllabic script
The field of Pharmacy can generally be divided into four primary disciplines:

Project work planning
The project plan is one of the most important and useful documents in your toolkit, and should be referred to and updated throughout the project lifecycle. Its initial purpose is to kick-start the project by convincing the decision makers (usually the people who control the funds e.g. the Project Board or Steering Committee) that the project is viable and will meet their needs and timeframes, budgets, expectations. If the project plan is poorly written or contains insufficient detail, the project may not even get past this first decision gate and may never actually get off the ground. Many viable projects have floundered at this stage due to poor planning and communication. On the flip side, if you can deliver a great project plan, it establishes your credibility as a project manager, starts the project on a sound footing, and provides the team with a mandate for action and a clear direction to follow.
