Key Performance Indicators
“Key Performance Indicators (KPIs) represent a set of measures focusing on those aspects of organizational performance that are the most critical for the current and future success of the organization” (Parmenter, 2010).
Data Collection
EffortBenefitsReward
Monitoring of KPIs requires a big effort due to data collection, therefore it must be abundantly rewarded by the benefits obtained through their use. (George, et al., 2005)
Key Performance Indicators must be effective for all the Laundries within the sector

It is a function ofproduction speed and the mix of daily time in which it is planned toproduce, called time load.
Evaluate the theoretical machineryperformance in terms of produced quantityof textiles, for a chosen mix, which could beprocessed every in absence of productioninefficiencies.
MixPracticalProductiveCapacity
Amount of daily produced textiles, with a chosen textile mix, actuallyprocessed in real conditions. It consider both the actual effective useof the machinery and the total amount of capacity losses that occurduring production.
To evaluate the actual practical (real)performance of the machinery, in terms ofamount of daily processed textiles for thechosen textile mix with actual realmachinery usage conditions.
Mix ActualProductiveCapacity
Amount of textiles, for a chosen mix, processed in one day using themachinery during all the scheduled time for production(with all HRavailable) but in real conditions. It take into account the total amountof capacity losses due to the inefficiencies that occur during the dailyproduction .
To evaluate the real performance of themachinery in terms of amount of textiles fora chosen mix that could be daily processedconsidering the total amount of capacitylosses.
Planningfactor
The ratio of: Production scheduled time (load time) and solar time forwhich is available our machinery. It’s expressed in percentage terms.
Assess the proportion of machinery that thecompany choose to use only for a certainperiod of time (load time) within the entireavailable time period (solar time of 24 h /day).
Utilizationfactor
Estimating the proportion of actual productive capacity that is used.It take into account any reductions in capacity for the specific needsof work adjustment (such as interruptions in production and / orproduction periods at reduced speed due to the reduction in thenumber of operators ).
The ratio between actual capacity andtheoretical productive capacity. it isexpressed in percentage terms.
OEE Evaluate the performance of the system in terms of efficiency. Thepossibility to exploit the theoretical productive capacity, holdingcapacity losses due to production inefficiencies such as equipmentfailure, delays or stops unwanted, minor stoppages.
The ratio between the practical productivecapacity and theoretical productivecapacity. It is expressed in percentageterms.

KPI Definition Scope - Purpose
TextileUseful life
The textile average useful life is the ratio (for aparticular type of head and a given period of time)between the amount of processed textile and theamount of new textile put into production system inorder to replenish the initial quantity which tends todecrease for various reasons
Estimate the average useful life ofown textiles in terms of averagenumber of washes.
TextileRotationIndex
The textile rotation index is the relationship between theamount of textile processed in a given time period andthe amount of textile supplied to customer for the sameperiod.
Provide an average of the number oftimes that a single cloth is processedin one month. It allows to assess thecorrect rotation of the textiles clothand to identify abnormal situationssuch as the presence of excessivestocks.
Textileamongcustomer
It is the percentage of textiles back fromthe client without any obvious damage orneed for special washing.
Assessing the correct use of textilesby the customer, highlightingpotential abnormal uses abnormalthat lead to a premature end of thetextiles life.

Utilities
Under the term "utilities" are grouped as the main energy resources, necessary for the operations of the production process. Utilities are eventually converted and distributed to the various production units where the utilities are transformed into useful work (Fawkes, 2007) through utility systems (electric, water plant, etc..).

Conclusions
•Measurement and improvement system of general validity
•possibility for the system to become a standard in the industrial sector
•manage the dissemination phase in order to ensure full implementation of the methods and techniques
•the collaboration with companies associations such as AssoSistema allows University to achieve high level results that can be quickly spread to a large number of companies.
Authors have analyzed different type of laundries, have caught all their peculiarities, have deployed a system which take them into account and finally have experimented the system and have implemented the needed adjustments.
•Many improvements and developments are still possible, and the results of the benchmarking will give the direction to follow.
