Success criterion

Once the problem has been defined, the system boundaries identified, and success criteria established, the GO model may be developed. The four basic steps in the development nt a GO model are ... 

Step I Defining the System - Collect the information needed to perform the analysis. Information needs include system descriptions, schematics, P IDs, logic diagrams, and operating procedures. Step 2 Establishing Inputs/Outputs - Every GO model begins with at least one input aiul may have many interfacing inputs. The output of the model is determined by the success criteria. 

In any given situation, there may be different levels of dependence between an operator s performance on one task and on another because of the characteristics of the tasks theraseb e.s. or because of the manner in which the operator was cued to perform the tasks. Dependence levels between the performances of two (or more) operators also may differ. The analyses should account for dependency in human-error probabilities. In addition, each sequence may have a set of human recovery actions that if successfully performed will terminate or reduce the consequences of the sequence. This information, coupled with a knowledge of the system success criteria leads to the development of human success and failure probabilities which are input to the quantification of the fault iices or event trees. With this last step, the HRA is integrated into the PSA, and Pl. ise 4 is complete. 

Representativeness can be examined from two aspects statistical and deterministic. Any statistical test of representativeness is lacking becau.se many histories are needed for statistical significance. In the absence of this, PSAs use statistical methods to synthesize data to represent the equipment, operation, and maintenance. How well this represents the plant being modeled is not known. Deterministic representativeness can be answered by full-scale tests on like equipment. Such is the responsibility of the NSSS vendor, but for economic reasons, recourse to simplillcd and scaled models is often necessary. System success criteria for a PSA may be taken from the FSAR which may have a conservative bias for licensing. Realism is more expensive than conservatism. 

The ESDs were then translated into associated event trees. A generic event tree was developed for all initiators not involving LOCA. The generic transient event tree for each category of the transient initiators and loss of offsite power were specialized by the impact of the initiators on the safety and support systems, from the success criteria of the mitigating systems, and the initiator-specific human actions which were modeled in the fault trees. 

The results of the pilot study will be most credible if success criteria are established ahead of time. This avoids the temptation to adjust criteria to demonstrate success. Success criteria should be related to the benefits of integration previously identified. Ideally they should be able to provide an indication of the economic benefit achieved. For example, reduction in... 

Establishing success criteria in advance of the pilot project improves the credibility of the findings and conclusions. 

The team should share your success criteria in advance with senior management, in particular your sponsor and other key staff. Find out whether they agree with the criteria, and if they do not, modify the criteria. 

Key lessons learned so far in the process, other than the amount of time and work required to develop an ELN system for 2500 scientists at 10 sites in 5 countries across 3 continents, are that setting out the success criteria up front allowed for a very focused selection process. Also, engaging a broad... 

Before the completed model could be put to work it needed to be tested against data from the plant covering a wide range of operating conditions. The test results were judged against clearly defined success criteria that take account of the proposed applications. In particular the accurate prediction of k-factor and exit brine strength was considered most important. 

A pre-requisite for the successful extraction of key NMR parameters from an experimental spectrum is the way it is processed after acquisition. The success criteria are low noise levels, good resolution and flat baseline. Clearly, there are also experimental expedients that can further these aims, but these are not the subject of this review per se. In choosing window functions prior to FT, the criteria of low noise levels and good resolution run counter to one another and the optimum is just that. Zero filling the free induction decay (FID) to the sum of the number acquired in both the u and v spectra (in quadrature detection) allow the most information to be extracted. 

Corrosion rates are clearly high and it is likely that this, plus turbidity levels, would be used as measurements for the effectiveness of any new cooling water program trial (success criteria). 

The Project Team Manager and members having been assigned to the project, their first task is to carry out a complete definition of the project. The team will know the overall goal of the project but its purpose and objectives will need to be clarified and redefined in more specific terms of defiverables, assumptions and constraints. Project definition enables all the stakeholders, both internal and external, to understand and agree upon the goals, responsibilities, assumptions and success criteria to be used. The planning of the project and the allocation of resources should only start once this has been done. 

The first and very important part of any plan is the exact definition of the aim, as explained in the previous chapter. This is followed by a list or sequence of major tasks or sections which each must be accomplished in order to achieve the aim. Since these major sections each define critical steps of the project, success criteria or objectives for each of these must be described and agreed. These objectives should specifically address known or potential difficulties (in our example the purity of antigen that is needed, the required test systems, etc.) and should be defined as exactly as possible at this stage and updated when necessary. The definition of objectives requires a reasonable knowledge of the subject and should thus be discussed and agreed with the specialists in these fields and with those who have to meet these objectives. 

Another important general objective which has been defined in the product profile may be the expected price limit for the production of the active ingredient or the formulated product. Specific tasks and measurable success criteria for process development and manufacturing, e.g. in terms of yields and recovery after purification, can be deduced from this price limit. Other very specific objectives and the majority of project tasks relate to specific registration requirements. 

What are the efficacy and safety differentiation targets and respective success criteria ... 

In 1988, D. Degner defined some semiquantitative success criteria [119] for electrochemical process parameters ... 

Successful delivery is verified against the success criteria within the risk management plan. Several stakeholders may need to confirm this verification. The site owner or developer will wish to know that the proposed management of the site is acceptable and that any new site valuation can be supported. The regulator may have to confirm that residual risks fall below regulatory thresholds. Finally, but most importantly, site occupants need to know that any risks to them have been reduced adequately. 

Provided that these and general information obstacles can be overcome, the next step is constructing a tender, inviting DM companies to offer a service. Identification of the limits of care, the numbers and types of patients to be included, the treatment protocols, and the outcome or success criteria are all vital considerations. 

Acceptance criteria Clear statement of success criteria for test.
