Six Sigma (sometimes stylized as 6σ) is a set of techniques and tools for process improvement.

It was introduced by engineer Bill Smith while working at Motorola in 1986.

Jack Welch made it central to his business strategy at General Electric in 1995.

Today, it is used in many industrial sectors.

A macro (short for "macroinstruction", from Greek 'long') in computer science is a rule or pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to a replacement output sequence (also often a sequence of characters) according to a defined procedure.

The mapping process that instantiates (transforms) a macro use into a specific sequence is known as macro expansion.

A facility for writing macros may be provided as part of a software application or as a part of a programming language.

In the former case, macros are used to make tasks using the application less repetitive.

In the latter case, they are a tool that allows a programmer to enable code reuse or even to design domain-specific languages.

Statistical process control (SPC) is a method of quality control in which statistical methods are employed.

SPC is applied in order to monitor and control a process.

Monitoring and controlling the process ensures that it operates at its full potential.

At its full potential, the process can make as much conforming product as possible with a minimum (if not an elimination) of waste (rework or scrap).

SPC can be applied to any process where the "conforming product" (product meeting specifications) output can be measured.

Key tools used in SPC include control charts; a focus on continuous improvement; and the design of experiments.

An example of a process where SPC is applied is manufacturing lines.

Microsoft Excel is a spreadsheet developed by Microsoft for Windows, macOS, Android and iOS.

It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications.

It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has replaced Lotus 1-2-3 as the industry standard for spreadsheets.

Excel forms part of Microsoft Office.

Computer software, or simply software, is that part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built.

In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Computer hardware and software require each other and neither can be realistically used on its own.
