Scenario:
You are managing a project to build a website. One of the tasks is to design the website layout. Based on historical data, you know that a qualified web designer can complete this task in 10 hours. However, this data does not include breaks or an efficiency factor.
Task:
1. **Break time:** 10 hours of work / 8 hours = 1.25 break hours 2. **Efficiency factor:** 10 hours * 0.80 = 8 hours 3. **Total Standard Time:** 8 hours + 1.25 hours = 9.25 hours
This document expands on the concept of Standard Time, breaking it down into specific chapters for a more comprehensive understanding.
Chapter 1: Techniques for Determining Standard Time
Determining standard time involves a meticulous process of observation, measurement, and calculation. Several techniques exist, each with its strengths and weaknesses:
1.1 Time Study: This classic method involves systematically observing and recording the time taken by a skilled worker to perform each element of a task. Multiple observations are necessary to account for variations. This technique requires careful planning, trained observers, and a standardized procedure to ensure accuracy. The resulting data is analyzed to determine the normal time, which is then adjusted for allowances.
1.2 Work Sampling: Unlike continuous time study, work sampling involves random observations of a worker's activities over a period. The proportion of time spent on each task element is used to estimate the time required. This is less disruptive than continuous time study but requires a larger number of observations to achieve the same level of accuracy.
1.3 Predetermined Motion Time Systems (PMTS): These systems, such as MTM (Methods-Time Measurement) and MOST (Maynard Operation Sequence Technique), utilize standardized data tables to estimate the time required for basic human movements. By breaking down a task into these basic movements, the total time can be calculated without direct observation. This is efficient for repetitive tasks but requires expertise in applying the chosen PMTS.
1.4 Historical Data Analysis: If sufficient reliable data exists from past projects, it can be analyzed to estimate standard times for similar tasks. This method is quicker and less disruptive than direct observation but requires careful validation to ensure the data's accuracy and relevance. It is most useful when tasks are highly repetitive and little variation is expected.
1.5 Expert Estimation: While less precise, expert estimation can be used for tasks that are difficult or impractical to observe directly. Experienced workers or engineers can provide estimates based on their knowledge and experience. This method is best used in conjunction with other techniques or for preliminary estimates.
Chapter 2: Models for Standard Time Calculation
Once the basic time for a task is determined using one of the techniques mentioned above, several models can be applied to arrive at the standard time. These models account for factors that affect worker performance:
2.1 Normal Time: This represents the average time a qualified worker takes to complete a task working at a normal pace. It is derived from the observed time, adjusted for any observed variations from normal performance.
2.2 Allowance Factor: This factor accounts for delays, breaks, fatigue, personal needs, and other factors that affect the worker's efficiency. Allowance factors can be based on industry standards, collective bargaining agreements, or company policies. Common methods include percentage allowances or time-based allowances.
2.3 Standard Time Calculation: The standard time is then calculated by adding the allowance factor to the normal time:
Standard Time = Normal Time * (1 + Allowance Factor)
Chapter 3: Software for Standard Time Management
Several software packages facilitate standard time management and project scheduling:
Project Management Software: Many popular project management tools (e.g., Microsoft Project, Primavera P6, Asana, Jira) allow for the input of task durations, resource allocation, and scheduling based on standard times.
Specialized Time Study Software: Some software packages are specifically designed for time study and work measurement, providing tools for data collection, analysis, and reporting.
ERP Systems: Enterprise Resource Planning (ERP) systems often incorporate modules for project management and resource allocation, enabling integration of standard time data with other business processes.
The choice of software depends on project complexity, organizational needs, and budget. The software should integrate well with existing systems and provide the necessary features for data management, analysis, and reporting.
Chapter 4: Best Practices for Implementing Standard Time
Effective implementation of standard time requires careful planning and execution:
Clear Definition of Tasks: Tasks must be clearly defined and broken down into smaller, measurable elements.
Trained Personnel: Workers involved in time studies should be properly trained to ensure accuracy and consistency.
Appropriate Techniques: The most appropriate technique for determining standard time should be chosen based on the nature of the task and available resources.
Regular Review and Updates: Standard times should be reviewed and updated periodically to account for changes in technology, processes, and worker skills.
Employee Involvement: Involving employees in the process can improve buy-in and accuracy. Open communication and feedback are crucial.
Focus on Continuous Improvement: Standard time should not be seen as a fixed target, but rather as a benchmark for continuous improvement. Analyzing deviations from standard time can reveal areas for process optimization.
Chapter 5: Case Studies of Standard Time Implementation
(This chapter would contain specific examples of how standard time has been successfully implemented in various industries and projects. Each case study would detail the challenges faced, the techniques employed, the results achieved, and the lessons learned. Examples could include manufacturing, construction, software development, or service industries.) For brevity, this section is left unpopulated, but examples could include a manufacturing plant improving production efficiency by 15% through optimized task times, or a construction company reducing project delays by accurately estimating task durations.
