Statit Software & Six Sigma


Introduction

Statit Software provides a family of continuous quality improvement (CQI) solutions targeted for the healthcare community. Our solutions are highly customizable and our staff is skilled at helping healthcare providers adapt these solutions to support statistical and quality analysis initiatives, regardless of whether they are philosophically based on TQM, CPI, or Six Sigma.

What is Six Sigma? Six Sigma is a business process improvement methodology capable of increasing positive outcomes. The concept is widely perceived to be an excellent approach to enterprise quality improvement initiatives. It is designed for setting goals and standards that would not have been considered possible more than a decade ago.

On the other hand, it is also important to remember Six Sigma as a methodology relies on tried-and-true statistical tools that have been used by quality practitioners for decades. These tools include, for example, control charts, normality plots, process capability indices, histograms, Pareto charts, tests of statistical inference, Analysis of Variance, etc. Statit Software has been providing customers with tools appropriate for Six Sigma quality initiatives since our solutions were commercialized more than 25 years ago.

Analysis

Statit incorporates a full suite of traditional analytical tools. For example, control charts for variables are used when the process under study concerns quality characteristics that are measured. Examples of this type of analysis would be used for the total number of procedures, length of stay, time to see a physician, etc. Statit provides the following charts that are used in these situations:

Variable Charts

Chart Type Description
X-bar Calculates and displays subgroup averages
R Calculates and displays subgroup ranges
s Calculates and displays subgroup standard deviations
Individual Displays each value
Median Calculates and displays subgroup medians
Moving Average Calculates and displays the moving average of subgroups
Moving Range Calculates and displays the moving range of subgroups
Cumulative Sum Calculates and displays a run-sum or V-mask chart
Process Capability Calculates and displays a histogram of data
Process Capability Analysis Calculates and displays a histogram of data for non-normal data

Attribute charts are used when the process under study concerns quality characteristics that are observed as either meeting some specified requirements or failing to meet the requirements. Examples of this would include incomplete admissions forms, patient falls or many of the Core Measures. Statit provides the following charts for these situations:

Chart Type Description
C Used for total number of defects
NP Used for the number rejected
P Used for fraction or percent rejected
U Used for defects per unit
Cumulative Sum Displays a function of defects per unit
Pareto Displays ordered bar chart

Statit further provides descriptive statistics, such as the mean or histograms and inferential statistics, such as hypothesis testing and forecasting. These include:

  • One and Two-Sample Inference
  • Enumerative Data
  • Analysis of Variance (ANOVA)
  • Regression and Correlation
  • Multivariate Analysis
  • Time Series
  • Survival Analysis

Fishbone diagrams, also referred to as Cause and Effect, and Ishikawa diagrams, are used to graphically display factors which contribute to a particular "problem" or characteristic under study. Bar charts, Box-plots, histograms and a variety of other analysis tools are also incorporated into Statit. There can be no doubt that Statit includes tools that can be appropriately applied in support of any Six Sigma program.

Reporting

Perhaps we should focus on how Six Sigma efforts stress the importance of searching for new ways of thinking. How instead of focusing on building skill levels within a separate quality department, Six Sigma initiatives attempt to put quality tools into the hands of large numbers of workers and managers throughout an organization. This is what Statit does best! After all, Statit was explicitly designed to support the easy construction of standardized reports and metrics and to rapidly communicate those results to others throughout an organization.

Only a web browser is needed to access Statit for basic use or administration. There is no need to install and maintain application pieces on everyone's desktop.

Statit can also accommodate users with different analytical needs and levels of expertise. For example, a Statit administrator can build a view for a specific user (CMO) or a group of users (Nursing) to meet their specific responsibilities. Additionally, individual users can create their own scorecard from a list of all public indicators for view. Six Sigma is all about Design, Measure, Analyze, Interpret and Control. Statit designed its product to help our customers utilizing Six Sigma with each of these "spokes on the wheel".

As an example, Statit provides a process expert with the requisite functionality to dynamically create corrective action plans and to measure and monitor the effectiveness of the plan against desired results. This type of accountability is a requirement for continuous quality improvement.

Low Cost / High Value

Statit is a flexible, quality solution. Anyone who is familiar with a point-and-click environment can use Statit to create customized reports, menus and forms. No HTML or other web development skills are required. There is no long-term need for IT involvement or highly specialized programming skills. Statit Software's customers have been able to begin producing quality improvement reports in a matter of minutes and continued to improve and expand their quality reporting on a continuous basis as they understand more and more how Statit can contribute greatly to their "quality journey". With Statit, you are only limited by your creativity in applying the solution.
