When compiling a budget for a new bungalow build, there are many factors to consider. Primary construction costs include items such as materials, appliances, HVAC and plumbing and are usually the largest part of the budget, up to 50 percent in most builds.
Statistical process control (SPC) is a method of quality control which uses statistical methods. SPC is applied in order to monitor and control a process. Monitoring and controlling the process ensures that it operates at its full potential.
Also called: statistical process control. The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit and a lower line for the lower control limit.These lines are determined from historical data.y comparing current data to these lines, you can draw conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation). Control charts for variable data are used in pairs.
