Order too much of an item and it sits in the warehouse eating up cash and storage space; order too little and the production line stalls waiting for the next delivery. Somewhere between those two costly extremes sits the right purchase quantity, and finding it consistently is one of the sharpest tests of a procurement function's maturity.

This training course by the Arab British Fellowship Training Academy equips participants to determine appropriate purchase quantities by weighing the variables that actually drive the decision: company activity and production nature, the real value of production needs, and the availability of financial, technological and human resources. Participants also examine how item characteristics — physical composition, shelf life, seasonal availability, substitute options — feed directly into quantity decisions, alongside the broader goal of balancing cost against operational continuity.

By the end of this course, participants will be able to:

• Identify the internal variables — company activity, production nature, resource availability — that determine appropriate purchase quantities.
• Avoid the most common mistakes in public and private procurement quantity planning.
• Plan, organize and secure an organization's material needs in the right quantity, at the right time, at the right price and quality, from the right source.
• Manage inventory movement to prevent both production stoppages and costly overstocking.
• Maximize profit by minimizing costs through applied purchasing economics.
• Factor item-specific characteristics — perishability, seasonality, available substitutes — into quantity decisions.
• Read market conditions and price trends before committing to a purchase quantity.

Target Audience:

• Staff involved in preparing and analyzing tenders.
• Purchasing and warehouse managers in commercial companies.
• Company and institution directors.
• Supply chain and inventory planning professionals.
• Anyone seeking to develop their skills in purchasing management.
