In this chapter, readers are given step-by-step instructions on how to access the software necessary to use SSD for R. They are also presented with a brief overview of the capabilities of the SSD for R package. These include basic graphing functions, descriptive statistics, many effect size functions, autocorrelation, regression, statistical process control charts, hypothesis testing, and functions associated with analyzing group data. In combination, R, RStudio, and SSD for R, all of which are freely available, provide a robust way to analyze single-system research data. This chapter demonstrates how to download the necessary software and provides an overview of the visual and statistical capability available with SSD for R.

This paper presents the application of Total Quality Management Method using Pareto diagrams and Statistical Process Control charts (SPC). These tools can be applied to both the manufacturing and construction sectors. A Pareto diagram can figure out some of the dominant problems of the projects, and SPC can determine whether the data variation is within control limits. SPC can measure the quality of performance in learning curve using the upper-range limit and lower-range limit of the control analysis. A case study was conducted on a precast beams installation at a rental multi-story residential project in Jakarta, Indonesia. Based on the measurement, some data are outside of the control limit due to the problems identified in the Pareto diagram. Further analysis by measuring the Process Capability Ratio (Cp) produces a value <1, indicating that project management needs to be careful about process variation.
