Allowed Time, also known as Standard Time, refers to the total time allocated for completing a job at standard performance. It encompasses not only the standard time required to perform the task but also additional allowances for fatigue, rest, personal needs, and contingencies.
Key Components and Computation
Allowed Time is computed by considering several components:
- Basic Time (BT): The time taken to complete a task under normal working conditions.
- Allowance Factor (AF): Time added to cover fatigue, rest, personal needs, and other contingencies.
The formula for Allowed Time (AT) is:
Types of Allowances
Various types of allowances are considered when determining Allowed Time:
- Fatigue Allowance: Time allotted to recover from physical/mental fatigue.
- Rest Allowance: Short breaks to recharge during a workday.
- Personal Needs Allowance: Time for necessary personal tasks (e.g., restroom breaks).
- Contingency Allowance: Extra time to cover unexpected delays or interruptions.
Special Considerations in Allowed Time
Industry Specific Practices
The required allowances often vary based on the industry and nature of work. For example, heavy industries may require higher fatigue allowances compared to office-based work environments.
Workforce Efficiency
Allowed Time calculations must balance efficiency and worker well-being. Excessively short times may lead to burnout, while overly generous times can reduce productivity.
Examples and Applications
Example Calculation
Consider a packaging task with a Basic Time (BT) of 1 hour. If the Allowance Factor (AF) is 20%, the Allowed Time (AT) can be calculated as follows:
Applicability in Project Management
Allowed Time is critical in project management for planning and scheduling. It ensures tasks are completed within realistic timeframes while acknowledging human limitations.
Historical Context
The concept of Allowed Time has evolved over time, rooting back to the early 20th century alongside developments in productivity and time-and-motion studies by pioneers like Frederick Taylor and Frank Gilbreth.
