استانداردهای ISO

سازمان بین‌المللی استاندارد ISO با هدف یکپارچه سازی تدوین استاندارد در سراسر جهان و ایجاد تسهیلات در تجارت بین‌المللی و همچنین حمایت از تولیدکننده و مصرف‌کننده و توسعه همکاریهای علمی تکنولوژیکی اقتصادی در ژنو واقع در سوئیس به تاریخ ۲۴ فوریه ۱۹۴۷ و با عضویت ۲۵ کشور فعالیت خود را آغاز نمود. پس از آن با پیوستن تدریجی دیگر کشورهای جهان اعضای این سازمان به ۱۳۲ کشور رسید.موسسه استاندارد و تحقیقات صنعتی ایران نیز یکی از اعضای اصلی این سازمان می باشد که به مشارکت در تدوین استانداردهای بین المللی پرداخته است. استانداردهای این سازمان در حال حاضر به ۱۱۹۵۰ مورد رسیده که این مقدار توسط ۲۸۵۶ کمیته تدوین و بررسی شده است.

 استانداردهای ایزو و کیفیت

اینکه با چه ابزار و با چه نظام و قاعده ای میتوان کیفیت محصول و خدمات را تضمین کرد همگی در استانداردهای تضمین کیفیت پنهان است. سازمان بین المللی استاندارد برای رفع نیاز شرکتها، استانداردهای مختلفی را تعریف کرده است که از جمله معروفترین آنها ایزو ۹۰۰۰  بوده و موج آن تعداد زیادی شرکتها ایرانی را فرا گرفته است. البته لازم به ذکر است که استاندارد ایزو با استاندارهای تضمین کیفیت معنای متفاوتی دارد ولی در ایران همچنان بسیاری از مردم و مدیران این دو استاندارد را با هم اشتباه می گیرند.

تفاوت استانداردهای « تضمین کیفیت » با استانداردهای « کیفیت محصول » بر میگردد به دید کلی ما به کیفیت شرکت و محصول مورد نظرمان. معمولا منظور از استانداردهای محصول حداقل مشخصه های فنی لازم برای کیفیت مورد درخواست است . در حالی که استانداردهای تضمین کیفیت حداقل الزامات کیفی لازم در همه ابعاد شرکت و فرایندهای آن را نشان می دهند. مثلا استاندارد محصول مشخصه های محصول مورد نظر ما را از نظر ، استحکام ، دوام و … تعیین می کند تا حداقل کیفیت قابل قبول را داشته باشد. اما استاندارد تضمین کیفیت تنها بر عوامل تاثیرگذار بر کیفیت که می باید از طریق فرآیندهای مختلف مثل تولید ، طراحی و خرید انجام می گیرد، تاکید می کند.
