It’s been a while since my last article—May of last year to be exact. Unforeseen circumstances prevented me from continuing with my monthly column, but I would like to pick up where I left off in “Selecting a Pump Repair/Service Shop.”
Not all pump repair shops are the same. Each individual shop has specific skill sets and limitations. Selecting the appropriate shop(s) (it is wise to have several to choose from) for your repairs depends on several factors. This is where the vendor qualification/selection process becomes interesting, as the on-site audit inspection requires validating what was discussed during the phone/email correspondence as well as additional information and observations. We will go into this in detail in future articles.
There are many types of pump repair shops. Each has their pros and cons. Which type is best for your specific needs? It all depends on your specific needs and expectations.
Take time to prepare for the site visit. If you or your team do not feel qualified, seek out a qualified third party. Develop a checklist of questions as well as specific observations you wish to verify. Do not trust your questions to memory. A site visit is necessary to physically validate what was shared during the interview and in emails, as well as additional information based on the type of pumps you need repaired.
The on-site inspections allow you to visually verify the building, lifting capabilities, equipment, etc., but what other critical information is needed to ensure you have selected the appropriate repair facility? Asking the right questions up front can save you down the road.
This portion of the audit process requires asking specific questions of the entire staff, as well as observation of how the staff interacts. Prior to the visit, prepare a checklist of areas you wish to visually verify along with the questions you want to ask. How the staff responds to the questions will speak volumes of the capabilities and workmanship the facility produces. In addition, visually verify documentation, specifically the QA/QC manual, as-found/as-built reports, shipping and receiving documentation, work orders (to shop) and inspection reports. The heart of any business is the people; a pump repair facility is no exception. You can have a state-of-the-art facility with top-of-the-line equipment; however, without well-trained, dedicated people to staff the facility, you have nothing but a lot of overhead.
In the pre-assessment, specific questions were asked regarding the service center capabilities, quality control methodology and people. What questions would you want to ask the staff while on-site? Remember, trust but verify. Using the interview questionnaire, have the list of questions, go through the list and request verification of their interview response.
Take the opportunity to meet with facility staff. During this segment of the visit, one must be sensitive to the subject matter and somewhat discreet. A few sample questions to give an idea of what to ask would be: Do you enjoy working here? Have you had training on QA/QC protocol? Have you been through safety training?
The manager may tell you one thing, but reality is something else. It is amazing what you hear from the workers. You may think this is being sneaky or underhanded. If so, I remind you of the ramifications if a critical pump fails under your watch.
