Testing Merchandise for Client Experiences


For over 80 years, individuals have turned to Client Experiences for trustworthy and authoritative assessments of merchandise earlier than they put their cash down. Immediately, the accountability for managing testing and rankings for tech-containing merchandise falls to Maria Rerecich, senior director of product testing on the impartial nonprofit member group.

Rerecich, an IEEE member, joined Client Experiences in 2013 after virtually three many years at Commonplace Microsystems Corp. (acquired in 2012 by Microchip Expertise). At SMSC she was answerable for built-in circuit design, validation, and product engineering of silicon chips utilized in PCs.


There are apparent variations between the 2 jobs, Rerecich acknowledges. For starters, Client Experiences charges merchandise; it doesn’t construct them. “We’re testing merchandise we don’t make and aren’t attempting to promote,” Rerecich says. “My groups are testing to check efficiency and verify if merchandise work as claimed, however we don’t should attempt to repair them in the event that they don’t.”

Her 30-person division specifies exams and develops the scoring and rankings, has roughly 30 individuals who work intently with the operations individuals within the lab, the place the exams are executed. “We work with a wide range of attention-grabbing merchandise in all varieties of classes and typically must develop sudden exams,” she says.

One instance was a state of affairs often known as Bendgate. “When the iPhone 6 got here out in September 2014, there have been experiences that the bigger mannequin was bending when individuals put it of their rear pockets and sat on it,” Rerecich remembers. “A lot of Bendgate movies have been posted of individuals bending telephones utilizing their thumbs. Whereas just a little flex could also be acceptable, you don’t need it to deform to the purpose the place it doesn’t come again, or to interrupt.”

This concern felt like an ideal match for the group’s methodologies and take a look at lab sources, Rerecich says.

“Individuals’s thumbs aren’t calibrated. We needed to arrange a extra scientific take a look at, quantify the forces wanted…and examine the iPhone 6 to different telephones. We had an Instron common testing machine, which does tensile and compression testing. We rigged it as much as do bending exams on half a dozen completely different telephones and fashions. We broke loads of telephones whereas doing testing.”

Preliminary bending-phone experiences had began coming in on a Wednesday, and by that Friday, Rerecich’s workforce had developed and accomplished testing.

Former low- or no-tech client merchandise corresponding to doorbells and canine collars at the moment are a part of the ever-increasing Web of Issues gadgets Client Experiences is now testing. Consequently, Rerecich’s mission has expanded to deal with privateness and knowledge safety issues.

“We’ve seen points in lots of client IoT merchandise associated to incomplete encryption, substandard authentication, or open vulnerabilities,” she says. “For instance, we’ve seen video doorbells and wi-fi house safety cameras sending electronic mail addresses, IP addresses, lists of instructions, community names, and even Wi-Fi passwords as unencrypted knowledge. Once we discover these [instances], we alert the producers, and in lots of instances they repair what we’ve discovered.”

She was one of many architects for the group’s knowledge privateness and safety initiative, and helped develop its Digital Commonplace framework of product testing standards for related services and products. She led a pilot take a look at of a number of cellular functions, which resulted in an app developer making fast enhancements to guard shoppers’ knowledge and privateness of delicate private and medical info. So far, Rerecich estimates, greater than 500 merchandise have been examined and rated for privateness and safety.

Rerecich’s recommendation to college students and up to date graduates consists of, “Be taught to touch-type properly and shortly, since you could spend extra time at a keyboard than in a lab.” Additionally, she urges college students to get uncovered to completely different areas of research and several types of programs. “Chances are you’ll not know what you want and are good at till you’ve tried it. For me, that was [a] chip design course at MIT—however I had additionally taken a course associated to biomedical engineering as a result of I assumed I needed to enter that. It’s good to maintain an open thoughts about completely different areas and be taught as a lot as you may.”

This text seems within the June 2022 print situation as “Maria Rerecich.”
