On the manufacturing shop floor, the principle of "value comes from the production of parts rather than charts" crucially applies when using practical statistical process control (SPC). The production worker should need to enter only a sample's measurements to get immediately actionable information as to whether corrective action (e.g., as defined by a control plan's reaction plan) is necessary for an out-of-control situation, and should not have to perform any calculations, draw control charts, or use sophisticated statistical software. This book's key benefit for readers consists of spreadsheet-deployable solutions with all the mathematical precision of a vernier along with the simplicity of a stone ax. Traditional SPC relies on the assumption that sufficient data are available with which to estimate the process parameters and set suitable control limits. Many practical applications involve, however, short production runs for which no process history is available. There are nonetheless tested and practical control methods such as PRE-Control and short-run SPC that use the product specifications to set appropriate limits. PRE-Control relies solely on the specification limits while short-run SPC starts with the assumption that the process is capable-that is, at least a 4-sigma process, and works from there to set control limits. Cumulative Sum (CUSUM) and exponentially weighted moving average (EWMA) charts also can be used for this purpose. Specialized charts can also track multiple part characteristics, and parts with different specifications, simultaneously. This is often useful, for example, where the same tool is engaged in mixed-model production. Readers will be able to deploy practical and simple control charts for production runs for which no prior history is available and control the processes until enough data accumulate to enable the traditional methods (assuming it ever does). They will be able to track multiple product features with different specifications and also control mixed-model applications in which a tool generates very short runs of parts with different specifications. The methods will not require software beyond readily available spreadsheets, nor will they require specialized tables that are not widely available. Process owners and quality engineers will be able to perform all supporting calculations in Microsoft Excel, and without the need for advanced software.

Zippers broke in just about a year making the bag unusable.
Color: Black Brown
I purchased this bag in March of 2025. In just over a year both zippers broke, and I was unable to fix them or use the bag. I don't expect a handbag to last forever but a year for both top zippers to break is a bit much. I would not buy this item again.

Great little budget tote
Color: Black, Color: Black
I use this as my everyday bag (with an organizer inside) and it's the best little bag I've ever had. It's sturdy but soft, the strap is easily adjustable to a bunch of different lengths, and it's roomy enough in the inside for average everyday needs plus the occasional extras! The material is thick enough to be good quality, but not overly inflexibly thick. I also covered mine in pinback buttons and enamel pins, and the fabric is really good for pins - They go on firmly and don't slide around. I saw a lot of complaints about smell, but mine had no bad smell at all!
