introduction
in many industries – from construction and oil and gas to information – contractors have a key role in the supply chain . their performance quality has a direct impact on the final product quality of the organization . a lack of correct assessment of contractors can lead to project delay , increased costs and technical problems . as a systematic approach , SQA provides a framework for selecting , evaluating , controlling and improving the quality of contractors .
what is a unit of contractors ?
SQA in the field of contractors assessment is a collection of measures aimed at :
initial assessment of contractors
confirm their quality qualification
periodic performance monitoring
- related risk management
continual improvement of service quality and service quality
it is done .
this process ensures that the outputs of the trusted brand are consistent with the requirements of the project .
- the main steps of contractors in contractors ‘ evaluation
2-1. primary evaluation ( pre – Qualification )
this includes the following :
past experience and experience
technical capability and engineering
quality standards used
such as iso 9001 or iso 45001
financial and human resources
objective : to determine whether supplier is capable of delivering quality work .
2-2. auditing and verification
presence or non – collaborative auditing to examine :
quality control processes
equipment and technologies used
documentation management system
risk management
ability to respond to project requirements
an audit is an important part of SQA that identifies the actual status of supplier.
performance evaluation ( Supplier )
after starting the همکاری , the performance of the supplier is measured at certain time periods .
typical indicators
quality of deliverables
timely delivery
accountability
budget and cost control
rework rate or product return
this step leads to continuous monitoring of water quality .
2-4. management of non – conformities and corrective actions
when observing quality problems
mismatch report ( NCR ) is recorded .
corrective action plan ( Corrective action ) is requested .
the results and effectiveness of the measures are evaluated .
this section is an important part of SQA because it prevents the error repetition .
2-5. classification and ranking of contractors
on the basis of the evaluation results , contractors are interested in :
a ( excellent )
b ( desirable but expandable )
c ( requiring strict surveillance )
d ( unacceptable )
they are divided .
this ranking helps management decisions to continue their activities .
- tools and procedures for evaluating contractors
3-1. standard evaluation
according to standards
iso 9001
iso 31000 ( risk management )
iso / iec 17025 ( in case of laboratory services )
3-2. scoring matrix
for a quantitative and objective comparison of contractors .
3-3. risk analysis methods
like :
FMEA
risk matrix
3-4. software evaluation software systems

EPM , PMIS , BMS
iv. the benefits of using SQA in contractors ‘ evaluation
increasing the quality of the final product
reducing duplication costs
reducing risks associated with delays and technical defects
selection of reliable and reliable contractors
improving transparency and better documentation
improving long – term relationships and contractors ‘ development - challenges in contractors evaluation
lack of accurate information from new contractors
supplier resistance in documentation
time consuming assessments
lack of standardisation in some industries
costs of performing quality processes
conclusion
SQA has a fundamental role in evaluating contractors in ensuring the quality of the product or service . this process will reduce project risks by creating a structured framework for selection , supervision and improvement of contractors and increases the quality of the output . organizations that use SQA to manage their contractors will have more sustainable , faster and cost – efficient projects .
