Tools charts

Computer databases allow for the easy and readily accessible time standard data. Often charts and tables are used in hard copy, especially when the engineer is familiar with such estimating tools. Charts and production information can be found in Ostwald (1992). When developed property, standard time data are considered to be accurate and relatively inexpensive for labor estimating. 

Whilst network analysis is a useful tool for estimating timing and resources, it is not a very good means for displaying schedules. Bar charts are used more commonly to illustrate planning expectations and as a means to determine resource loading. 

This study describes one stage of a soft tool realisation, which facilitate and improve the task of the expert for x-ray image interpretation and decision-making. We are interested by tbe first four stages of this flow chart.

The structure diagrams can be verified according to free valences or atom labels. Properties such as molecular... 

The principal tool for performance-based quality assessment is the control chart. In a control chart the results from the analysis of quality assessment samples are plotted in the order in which they are collected, providing a continuous record of the statistical state of the analytical system. Quality assessment data collected over time can be summarized by a mean value and a standard deviation. The fundamental assumption behind the use of a control chart is that quality assessment data will show only random variations around the mean value when the analytical system is in statistical control. When an analytical system moves out of statistical control, the quality assessment data is influenced by additional sources of error, increasing the standard deviation or changing the mean value. 

Control charts were originally developed in the 1920s as a quality assurance tool for the control of manufactured products.Two types of control charts are commonly used in quality assurance a property control chart in which results for single measurements, or the means for several replicate measurements, are plotted sequentially and a precision control chart in which ranges or standard deviations are plotted sequentially. In either case, the control chart consists of a line representing the mean value for the measured property or the precision, and two or more boundary lines whose positions are determined by the precision of the measurement process. The position of the data points about the boundary lines determines whether the system is in statistical control. 

Another important quality assessment tool, which provides an ongoing evaluation of an analysis, is a control chart. A control chart plots a property, such as a spike recovery, as a function of time. Results exceeding warning and control limits, or unusual patterns of data indicate that an analysis is no longer under statistical control. 

The automated amino acid analy2er depends on ion-exchange chromatography (117) and is now a routine tool for the analysis of amino acid mixtures (118). This most advanced machine can detect as Htde as 10 pmol in ninhydrin reaction analysis. One-half to two hours are required for each analysis. An analysis chart is shown in Figure 2. 

Seven of the tools of quahty have been summarized (43). The first tool is a flow chart, used to help understand the organizational flow of a procedure or process. A flow chart should be constmcted with the fiiU participation of the people who do the work. Its principal benefit is to enable teams, such as problem-solving or productivity improvement teams, to reach a common vision of the work flow. Its use enables the improvement effort to begin with this common understanding. Figure 3 contains an example for manufacture of a polymeric material. 

The check sheet shown below, which is tool number five, is a simple technique for recording data (47). A check sheet can present the data as a histogram when results are tabulated as a frequency distribution, or a mn chart when the data are plotted vs time. The advantage of this approach to data collection is the abiUty to rapidly accumulate and analy2e data for trends. A check sheet for causes of off-standard polymer production might be as follows ... 

The pareto chart, tool number six, is a special type of histogram (48) where the frequency data is grouped in order of decreasing occurrence or other measures of importance rather than in sequential or numerical order. The chart, an example of which is shown in Figure 6, illustrates the causes in decreasing order of importance. It enables the improvement effort to be focused where it can have the most impact and is an effective management communication tool. 

An important part of the decision-making tool flow chart (see Fig. 1) is the redefinition of the specifications by the sensor customer after the surveying and testing of commercial sensor systems. This process almost always involves a downgrading of the expectations of the sensor customer, but it can also force a reaUstic evaluation of what sensor information really needs to be made available and at what cost. 

Chemical incompatibility charts can help in organizing available data on the incompatibilities existing between expected mixtures. Frurip (Frurip et ah, 1997) gives one procedure for developing a chemical compatibility chart while describing some of the tools available. CCPS G-13 also provides a table of known incompatibility hazards. 

The varianee equation provides a valuable tool with whieh to draw sensitivity inferenees to give the eontribution of eaeh variable to the overall variability of the problem. Through its use, probabilistie methods provide a more effeetive way to determine key design parameters for an optimal solution (Comer and Kjerengtroen, 1996). From this and other information in Pareto Chart form, the designer ean quiekly foeus on the dominant variables. See Appendix XI for a worked example of sensitivity analysis in determining the varianee eontribution of eaeh of the design variables in a stress analysis problem. 

The so-called Q7 tools and techniques, Cause and Effect Diagrams, Pareto Analysis, etc. (Bicheno, 1994 Dale and McQuater, 1998 Straker, 1995), are applicable to any stage of the product development process. Indeed they support the working of some of the techniques mentioned, for example using a Pareto chart for prioritizing the potential risks in terms of the RPN index for a design as determined in FMEA (see Appendix III). 

The Nichols chart shown in Figure 6.26 is a rectangular plot of open-loop phase on the x-axis against open-loop modulus (dB) on the jr-axis. M and N contours are superimposed so that open-loop and closed-loop frequency response characteristics can be evaluated simultaneously. Like the Bode diagram, the effect of increasing the open-loop gain constant K is to move the open-loop frequency response locus in the y-direction. The Nichols chart is one of the most useful tools in frequency domain analysis.

Another helpful tool is a project control chart, which uses budget and schedule plans in a quick status report of the project. It compares actual to plan, calculates a variance on each task completed, and tallies a cumulative variance for the project. 

Availability of decision support tools like control charts and color charts is also important. In situations that are out of control, these tools support people in making homogeneous decisions dealing with quality failure (e.g., color deviation). 

At Novartis, so-called BioavailabiUty Radar Plots [44] are used to visually display the oral absorption potential of molecules. On these plots five important calculated descriptors (log P, molecular weight, PSA, number of rotatable bonds and water solubility score [45]) are displayed on the axes of a pentagonal radar plot and compared with predefined property limits (green area) which were determined by the analysis of marketed oral drugs. These plots provide an intuitive tool that displays multiple parameters as a single chart in a straightforward but informative way, providing visual feedback about the molecule s bioavailabiUty potential (Fig. 5.5). 

The ultimate goal of all scientists is to analyze their data thoroughly until they are sure that it is valid and to then analyze it in a more global context and discuss it with their colleagues. This workflow requires enterprise level IT tools that can effectively compare and correlate multiple HTS campaigns that generated millions of results from hundreds of thousands of compounds, recognize and chart trends and hierarchies of association and help the scientist visualize them, annotate them, and render the visualizations in media that can be used to share that vision with other members of the team.
