Rework - meaning

Rework means the continuation of processing that will make an item conform to specification. Rework requires only normal operations to complete the item and does not require any additional instructions. Rework when applied to documents means correcting errors without changing the original requirement. 

Lack of an effective rework means low-quality batches may be discarded. 

Some math word problems have answers that just don t seem right. These answers are the ones that definitely need checking. Other answers are just obviously wrong, meaning that the problem needs reworking. 

Now you have two possible answer choices, a and e, either of which works with your sentence. That means your sentence is not specific enough and needs to be reworked. One technique that will help you come up with specific sentences is to use active verbs. Notice that the verb in A tooth is part of a mouth is a state-of-being verb, the verb is. An active verb would be more helpful. 

The concept of validation came up in the 1970s in association with sterilization procedures and was extended to all steps of pharmaceutical manufacturing procedures. Validation means proving that any and all procedures, processes, equipment, material, operations, and systems comply with the expected performance. Well-planned and well-conducted validation studies constitute GMP principles once they guarantee a consistently safe and efficacious final product. Validation is important for companies, first for QA, and also for cost reduction, decreasing failures, rejection, reworks, recalls, and complaints. The positive aspect of validation is an increase in productivity, as a consequence of a well-controlled process. Validation is required by the regulatory agencies of many countries. 

Another megatrend in this competitive business environment is that all production processes need to be world-class and lean. This means that processes must be automated lead times shortened rework, scrap, and waste minimized or eliminated and less product must appear in inventory. This places a burden on the adhesive formulator in that the products not only must perform in service (e.g., creep resistance, peel strength) but also must perform in the assembly process (e.g., fast cure time, minimal scrap, low energy cure). 

Since numerous temporary piping connections are made to accommodate multipurpose use of several tanks during a campaign, leaks and/or small spills can occur. Thus, the cell cubicle floors and external portions of the equipment are flushed thoroughly after each campaign. All of the rework materials obtained between campaigns are accumulated, processed by means of one or two cycles of the Cleanex batch extraction process to remove miscellaneous impurities, and recycled to the next campaign. 

Obviously, the higher the regression coefficient, the better the reproducibility obtained of the system. In this context, it is important to take in mind that the same information that gives the regression coefficient can be obtained visually from the actual output ( v )-model output (y,) graph. If all points lay over the line y = y, it means that our model describes satisfactorily the process. On the contrary, if points are far away from this line the model has to be reworked. 

Major amendments to documentation was required in order to address 18% of the errors identified the rest only required minor document change. Remember, not aU changes are limited to a single document. All document changes, however, need to go through change control, which in practical terms means rework and delays. 

At this meeting, a discussion about possible rework procedures may be appropriate. The ability to recover materials, especially expensive drug actives, is desirable. Early identification of steps where rework may be possible allows for procedures to be tested, verified, and put in place, should they be needed. For pharmaceuticals, rework procedures may be used only if they are appropriately documented, validated, and approved by the responsible corporate and government bodies. Rework procedures are not an automatic means for handling out-of-specification product lots but rather for identifying where an effort may be implemented successfully. Logistics and economics, as always, dictate whether a rework should be considered. 

The transform to be reworked was announced in advance, with literature references to the reaction being covered. A person familiar with ALCHEM (a "coder") gave a step by step walkthrough of a transform. The chemical and structural meaning of each statement was explained, triggering a wider discussion of the scope and limitations of the reaction. As new aspects of... 

This is the commercial means used by manufactiu ers of Technical Grade DMSO. The product of these very carefully controlled distillation processes still contains unacceptable levels of DMS and the other odor-causing materials. If continual reworking of the pure DMSO stream is carried out, the impurity concentration stabilizes at a low-level steady-state value, which is still unacceptable by pharmaceutical standards. 

When the above blocks dry a yellow crust is formed about half an inch thick. This is removed at a certain stage and the rest dries white. It has not been found possible to devise means to prevent the formation of this crust. The amount cut away represents about 25 per cent, of the total starch and the whole of this material has to be reworked in the next batch. The starch is generally blued with ultramarine. The blocks remain in the drying chamber... 

The treatment of product residues and reworked or recovered material and the means of their inclusion in a subsequent batch should be specifically authorised and documented.
