Tolerance stackup is the cumulative effect of part tolerances on the final assembly dimensions, impacting fit and function.
Tolerance stackup helps identify potential assembly issues before production.
For example, if part A has a tolerance of ±0.1mm and part B has ±0.2mm, their combined effect needs analysis.
Stackup analysis can be done using worst-case or statistical methods to predict assembly variations.

FIFO (First In, First Out) and LIFO (Last In, First Out) are methods for managing data and inventory.
FIFO processes the oldest data first, like a queue.
Example of FIFO: A line of customers at a bank.
LIFO processes the newest data first, like a stack.
Example of LIFO: A stack of plates where the top plate is used first.
To introduce oneself effectively, focus on clarity, confidence, and relevant details about your background and expertise.
Start with your name and current position, e.g., 'I'm Jane Doe, a Senior Data Analyst at XYZ Corp.'
Mention your educational background briefly, e.g., 'I hold a Master's in Data Science from ABC University.'
Highlight relevant experience, e.g., 'I have over 5 years of experience in data analysis, ...
