Transcript of Productivity Benchmarking in Spinning Mills

Productivity Benchmarking-Goals Key Performance Indicators Reference Stds-PB Few Case Studies Route Map for PB Use of ERP

Manufacturing Excellence will be the Result of

Productivity Benchmarking

Market supremacy can be achieved only and only if

Organizations Excel in all their Performance Metrics

Honda City and Maruti

Park Dale mills used 2000 employees in 1980 to produce 1 lac kg per week

In 2014 the same volume is produced with 140 employees

When all mills find it difficult to cross 145 gps in Modern Ringframes in 40s Combed Hosiery, one group of mills in South broke the barrier and achieved 175 gps using Compact systems

Compact spindleage shoot up in southern mills, by Commercial exploitation

When Spg mills were at stress to achieve 5% profit margin one mill in Tamil Nadu consistently reported 10% profit for more than 5 years with Permanent employees.

It is only because of its ` No. 1` position in Combed Compact Weaving yarn Market with a command on Premium

When Mills were struggling to achieve imperfections below 70 in 30s CH with 74% YR, one mills near Dharapuram consistently achieved less than 50 imperfections with an YR of 77% and stood first in Export yarn Quality

Efforts taken :Ginning is controlled by them

Reduce Manufacturing Cost Better Use of Assets Top Quality &Efficiency (RFT) On time Delivery Service level Excellence Control on Inventory levels

Higher production per spindle(gps) Higher productivity per

employee(kg/employee or HOK) Higher yields(YR) Less energy to produce(Units per kg) Control on Consumables Control on Packing Cost

Utilisation Efficiency/Break up of Losses

Maintenance Repairs Traveller changes Lot changes Unscheduled power related stoppages

Build the required Quality into the product

Relate In process Q to final process Q

ZDQC-Zero Defect Quality Control

Identify potential failure points and plug it

Ratio of Actual no of days taken to deliver

to Committed no of days to deliver the lot

(Question of Survival in a Competitive Market)

SIMA Technofacts Survey reports

SITRA CPQ reports

SITRA-30th CPQ report

“Mills has increased their Contribution per spindle per year by

35% over a period of 6 years”

TPM -Total Productive Maintenance

FMEA-Failure Mode Effect Analysis

Can help the mills to reduce Breakdowns to near zero.

YR can be increased by controls on Waste monitoring from Blow room itself.

Each Zone has the task of `specific type of waste` removal

Mills Status-RF with AD and Modern Machinery in all departments

Mills Target-4.1

Power spent on compressor has been brought down from 4.1% to 3.4% by plugging Airleakages in Lap preparation in Comber Department and also in Autoconer

RH is displayed in broad &visible letters in Autoconers/Spinning departments.Shopfloor has been educated on Humidification plant efficient running

Ukg is brought down to 4 and being improved further.

Mills Current level-74% Count pattern -Medium SC and C Target planned -3% improvement

Improved areasCard waste Zonewise analysis revealed SFD

waste is abnormally high at the level of 2%.Reduced to 0.5%

Hard Waste was found to be abnormal due to poor work practices in RF.Retrained the workforce and reduced the hard waste from 0.9 to 0.6%

In Semicombed Variety mills has not done Conditioning.Effectively restarted.

Sweepings found to be 0.8%-Unusually high.On checking it is a mixture of Usable waste and Sweeps.Educated the sweepers and concerned department tenters.Reduced the same to 0.5% level

Finally the mills is able to exceed its expected target of 3 and achieved 3.5%.

Final YR -77.5%

Monitoring & Maintaining Moisture content in Mixing and outgoing yarn

Monitoring and Maintaining Moisture content in Saleable waste

Strict monitoring and control of AWES waste level by visual checks in Compactors-weekly

Tare weight control in Packing Weighment of Mixing at the time of Laying Ensuring 65 to 70 % in Packing department

Empowered Employee Beliefs and Attitudes Belongingness of Employees

Any reward/incentive/benefit system must be focussed on `Self development of Employees towards empowering him`so that he becomes `Mouth piece` for our units.

Education on Systems available to all employees through all channels of Communication

Short and brief meetings at villages where our Employees are concentrated

`We are thrilled by news that 160 employees are graduated in one group of Mills.One employee in that group Joined TCS too.`

Training and Retraining of Employees play a vital role in realising our ME/PB Goals

If Training system needs to be effective, Employee Retention is the Keyword

Data Collection plays a vital role in system towards Manfacturing excellence

Direct transmission of data without any manual intervention needs to be ensured wherever it is possible

One time entry and Precise data are the basis of ERP implementation

NVA`s must be eliminated at all levels of Hierarchy through ERP

Availability of Reports as Structured

Develop Alert Sytems

Deviation Levels to be attacked then and there

SWOT analysis Create Management Vision and Mission

Break up of Mission into Performance Objectives

Develop Suitable and Effective Performance linked Wage structure

Mock Implementation and Nodal wage increase-Communicate to employees and get feedback

Apply suitable corrections and Implement

Review periodically and revise targets in comparison to Benchmarked levels

Develop Customer Satisfaction Index

Implement essential pillars of TPM

Use Techniques of FMEA for reduction of Breakdowns in Machines and Quality

Training and Retraining of Employees with proper Communication tools

for Retention form the foundation of any System towards

MANUFACTURING EXCELLENCEThrough

PRODUCTIVITY BENCHMARKING
