Study Notes
Successful Product Design
- Successful product design blends aesthetics, functionality, and user experience.
- It requires understanding user needs and market demands to create sustainable solutions.
R&D in Product Design
- R&D stands for Research and Development.
- It involves systematic efforts to innovate and improve products through research and engineering processes.
Product Design Process
- The product design process includes stages like idea generation, conceptual design, prototyping, testing, and final production.
- Each stage focuses on refining the design to meet user requirements and production capabilities.
Purpose of Defining Capacity
- Defining capacity in production and operations management clarifies the maximum output capability of a production system.
- It helps in planning and resource allocation to meet market demand efficiently.
Focus of Product Designers
- Product designers concentrate on empathy, ensuring products address real-world problems faced by users.
- They prioritize usability, accessibility, and the overall user experience in their designs.
Key Difference between PERT and CPM
- Program Evaluation Review Technique (PERT) emphasizes time management in projects with uncertain activity durations.
- Critical Path Method (CPM) is focused on managing tasks with known durations to identify the longest path in project scheduling.
Calculating Expected Time (Te) in PERT
- The expected time (Te) of an activity is calculated using the formula: Te = (To + 4Tm + Tp) / 6
- This formula incorporates optimistic, most likely, and pessimistic time estimates to find a weighted average.
Approaches to Calculate Critical Path
- Both PERT and CPM utilize network diagrams to visualize project tasks, dependencies, and timelines.
- The critical path is determined by identifying the longest sequence of dependent tasks that define project duration.
Components of Time Estimates in PERT
- Time estimates in PERT involve three components: optimistic time (To), most likely time (Tm), and pessimistic time (Tp).
- These estimates are used for a more comprehensive understanding of project timelines and uncertainties.
Expected Time Calculation Example
- If To is 4, Tm is 6, and Tp is 8, the expected time (Te) is calculated as: Te = (4 + 4(6) + 8) / 6 = 6
- This shows the methodology applied in estimating activity durations based on varying scenarios.
