Problem Statement
The Program Management Department has to manage a large number of projects simultaneously.
Monitoring of various projects becomes time consuming.
A centralised database which would be reviewed and updated monthly was desired.

Conclusion
The Project Health Report is a handy management tool.
It is user-friendly and can be used by anyone with minimal knowledge of MS Excel.
It is colour coded for quick analysis with financial data represented in the form of tables and charts.

Project Details
Objective: To conduct a time study of the Muffler
End Spinning Machine
Method: Video Time Study
Aim: To compute production target for each shift
of a working day

Introduction
A Time Study is conducted with the aim of boosting productivity rates.
Time study duration varies according to the product being manufactured.
Method study and Time study are usually conducted together.
It is initiated when: Desired productivity rate is not achieved An improvement is desired There is a change in layout/machinery A periodic review is to be conducted

Method
Time and Method study was conducted in the following manner:
1. A video study of each of the individual operations in the defaulting manufacturing cell was conducted
2. The station with operating time much greater than machine cycle time was considered to be the bottleneck operation.
3. A thorough Method and Time Study is then carried out on the bottleneck operation to determine the cause of delay
Note: Always conduct a the study with a highly skilled operator manning the machine

Bottleneck
The Spinning Machine was found to have a much greater operating time.
It was selected for further study.
Machine Cycle Time = 22 seconds
General Operating Time = 39.4
seconds (avg)

Next Step
The End Spinning Machine was further studied.
The actions of the operator were divided into the following elements:- Walk, take muffler and load
on M/C. Take unloaded job and place
on table Press cycle start and observe
1 rotation Walk to LT & right LT value Unload job and put on table,
load new job, initiate test Check unloaded job and put
in FG trolley

Allowances
An operator will not perform his operation with 100% consistency.
The ISO Handbook has specified guidelines regarding allowances for the worker’s safety and welfare.
These allowances are calculated into the machining time.
