We have been on a bit a tear (or rant) about FMEAs. We suggest the FMEA documentation is part of the core of a design process. The ultimate approach we have seen is that of Michael Anleitner (The Power of Deduction: Failure Modes and Effects Analysis for Design, Quality Press, 2010), which uses functional analysis […]

We submit that a Failure Mode and Effects Analysis (FMEA) review is a form of design review. After all, one of the purposes of a design review is to try and remove defects before they appear in the product and that is the entire rationale for the FMEA in the first place. Yet, most of […]

We addressed the issue of the modular FMEA in a previous blog. We also suggest that the FMEA in its various guises is also a great place to capture lessons learned. In the medical, aerospace, automotive, and food industries, some kind of FMEA is a required document. Since we already must create these documents, why […]

A modular FMEA is a modification of the standard Failure Mode and Effects Analysis tool into meaningful components. For example, we can select “stepper motor” as a component of a typical instrument cluster used in the dashboards of truck and autos. We would then create our FMEA to deal with all issues related specifically the […]

Configuration auditing occurs so we can verify that what we said we were going to do actually happened. MIL-STD-973 specifies two flavors of auditing: functional and physical. Functional configuration auditing occurs when we verify that the change functions as the engineering change proposal specified it would. A change can be to hardware, software, or both […]

Configuration control is generally, what first comes to mind when somebody brings up the topic of configuration management (CM). While it lies at the heart of the system, all the components of a CM system are critical. The purpose of this component is to: Maintain and control configuration baselines (known and defined states) Document and […]

Once we are using a configuration management (CM) system, how do we ascertain the status of our engineering change? Configuration status accounting (CSA) is the method by which we accomplish this record tracking. We can get software support by using a dedicated tool or implementing a dedicated database that tracks what we want tracked: Approved/rejected […]

One of the principal roles of configuration management (CM) is to protect us from ourselves. In so doing, we also protect our suppliers and our customers. When high school or college students first encounter bills of materials, they experience shock and awe. An automotive wire harness with 368 leads must have a bill of materials […]

by Jon M Quigley and Wally Stegall This post is a flashback to the earlier series about prototypes (https://valuetransform.com/planning-prototype-parts). A recent event reminded me of one other area we did not cover in this series. Such is the way of the blog. Consider the organization that decides to limit the number of prototype parts to […]

by Kim H Pries When we are engaged in prototype development during the early to late middle phases of our new product delivery process, we usually purchase components through maintenance, repairs, and operation (MRO) purchasing. This type of purchasing is managed on an as-needed basis, and often, is not automated. We purchase the parts we […]
