Specification Spec

It is possible to implement the Scheduler without a Session class and without unique and distinct objects for each session such an approach would be quite common when you re assembling existing implementation components or legacy systems, such as a calendar (with events) and an employee database (with employees). When designing, some people like to distinguish those types they have decided to implement—design types— from those that are used simply to help write a specification—spec types. Design types can be drawn with a heavier border. [Pg.148]

Now that you ve identified the key inputs, the rest of the plan will concentrate on how to keep the process in control. Specification (spec) limits are proven standards or measurements that set the boundaries for each input or output. When the output is operating within these boundaries (in spec), the process remains in control. When the output operates outside spec limits, the process goes out of control. Spec limits can be a variable range (such as the 1.5 to 3.5 second range for our drive-through camera to snap a picture), or an attribute (we use yes/no for our database input because the driver s image is either in the database or it s not). [Pg.335]

The angle between Z and R is called the "phase angle," symbolized by the Greek letter ( ) ("phi"), and its value is 45° in Fig. 9.7, but it can be adjusted by changing R. For a pure capacitance having zero series resistance, the phase is 90°, but for a pure resistance it is zero. The other angle, 90° - ( ), is called 5 ("delta"). Note that the R / X is the tangent of delta, and in fact it is referred to quite often in discussions about capacitors. Synonyms used in specifications ("specs") include ... [Pg.101]

In a few apphcations, improving the control system leads to a reduction in orf-specification product and thus improved process economics. However, in most situations, the process is operated sufficiently far from the constraint that very little, if any, off-specification produc t results from control system deficiencies. Management often places considerable emphasis on avoiding off-spec production, so consequently the target is ac tuaUy set far more conservatively than it should be. [Pg.730]

Clean up includes identifying, gathering, storing (when appropriate), and classifying materials associated with a specific toll. Decisions can then be made as to which raw materials, intermediates, and product will be shipped back to the client or kept by the toller. Some off-spec product, retained samples, or unused intermediates may be considered waste materials at this point. Equipment clean up can be extremely important to preserving quality and process safety integrity prior to the next production run of a new product. [Pg.136]

Testing and QC are discussed but often the least understood. Usually it involves the inspection of materials and products as they complete different phases of processing. Products that are within specifications proceed, while those that are out of specification are either repaired or scrapped. Possibly the workers who made the out-of-spec products are notified so they can correct their mistake. [Pg.299]

Computer-aided flow-simulation programs are also available for dies. All the programs can successfully predict a certain amount of shrinkage under specific conditions that can be applied to experience. The actual shrinkage is finally determined after molding or extruding the products. When not in spec process control changes can meet the requirements unless some drastic error had been included in the analysis. [Pg.443]
