Analysis after planning completion

Due to safety requirements ascertained with respect to the plant, essential system changes might result. In the event that, with due consideration for necessary changes, the planning of the plant is completed. analysis after planning completion takes place. The completed planning documents are checked to see whether the technical design observes specifications and can attain the safety aim. 

The following will be a discussion of the principle of analysis after planning completion. Subsequently the Lawley procedure will be discussed... 

This is the last step of risk analysis. After having completed the risk analysis and defined the measures to reduce risks, a further risk assessment must be carried out to ensure risks are reduced to an accepted level. The risks cannot be completely eliminated risk zero does not exist, thus a residual risk remains. This is also because only identified risks were reduced by the planned measures. Thus, the residual risk has three components ... 

Cost-benefit analyses (CBA) for each building protection system might have to be updated several times during the life cycle of a system. The first round of cost-benefit analysis is used to get concept approval to proceed with a more detailed one. A detailed cost-benefit analysis would then be conducted early in the design phase of the protection system. After the detailed analysis has been completed, the development and implementation plans might call for a prototype system or a pilot phase to test the costs and benefits on a small scale before the full system is implemented for all users. If a pilot phase is needed, a third version of the cost-benefit analysis would reflect revised costs and benefits and would be used to decide whether to proceed with full implementation of the system. The post-implementation review of a system might require an updated cost-benefit analysis to determine whether the expected benefits are being achieved and to decide whether the operation of the system should continue as implemented or be modified to achieve benefits that justify continued operation. 

Following the completion of all the above described tests, the gathering of data for a specific project was carried out. The first use of the models has been for the analysis of different options for the reset of an Axle Counter controlled Signalling Section after planned maintenance (Lucic, 2005a). Simulation of two options has shown significant differences in safety risk. 

The feed-back design (Figure 6.3.3 on the next page) was a 2-level, 6-variables central composite plan that required 2 = 64 experiments for the full replica. A 1/4 replica consisting of 16 experiments was made with an additional centerpoint. This was repeated after every 3 to 4 experiments to check for the unchanged condition of the catalyst. The execution of the complete study required six weeks of around the clock work. In the next six weeks, mathematical analysis and model-building was done and some additional check experiments were made. 

If new knowledge becomes available regarding important covariates after completion of the statistical analysis plan then modify the plan at the blind review stage. 

In line with this, the interim analysis plan was revised and only one interim was to be conducted for both efficacy and futility after 40 per cent of the patients had completed 3 months of follow-up. Since the two proposed analyses were not equally spaced, a spending functions were needed to revise the adjusted significance levels and these turned out to be 0.0007 and 0.0497. 

The model for an analysis and reporting strategy presented emphasizes the importance of a structured plan of work in combination with team s commitment, in the attempt to complete participation in the OPCW proficiency-testing scheme successfully. However, teamwork among laboratory staff may not be enough successful participation requires full support from management too. After all, management must understand that participation requires full devotion from the laboratory other tasks preferably have to wait for a later point in time. 

Once the desired end-point is determined and the current situation is assessed, a gap analysis is completed and objectives are set to close the gaps. An important step in the process is the prioritization of objectives, based on balancing available resources with risks. The development of the plan is ideally a participative one, involving the maximum number of people. After the plan is developed, personal and team performance objectives need to be aligned with the goals of the plan. Finally, it is necessary to integrate the quality plan with the overall business plan. 

Completeness and transparency are key principles in the reporting of a meta-analysis for the evaluation of safety in the regulatory framework. The protocol and the statistical analysis plan should be completed and finalized prior to the conduct of the meta-analysis. Any deviations or additional investigations after the finalization of the protocol should be clearly identified as such. 

After the initial analysis of the sequences of events, O Connor visited both of Gunther s parents and explained the main causes on which the review team was focused. He also showed them the initial list of completed and planned changes intended to prevent future near misses. The couple took notes on the information that O Connor had shared, and they asked if Gunther could be moved to another unit of the hospital. O Connor knew that the employees on a different unit were no less likely to make mistakes than were the employees on Gunther s current unit in fact, the staff on the unit... 

It is planned further to extend the parameters range in order to cover more realistic conditions area. Preliminary analyses shown that 5-10 % of sodium can be sprayed in the case of large rupture. After completion of the experiments planned detailed analysis is scheduled.
