• Deming: es una estrategia de mejora continua de la calidad en cuatro pasos.Plan, Do, Check, Act (Planificar, Hacer, Verificar, Actuar).Los resultados de la implementación de este ciclo permiten a las empresas una mejora integral de la competitividad, de los productos y servicios, mejorando continuamente la calidad, reduciendo los costes, optimizando la productividad, reduciendo los precios, incrementando la participación del mercado y aumentando la rentabilidad de la empresa u organización.

• Kaisen: “mejora continua que involucra a todos”. Es pues un sistema integral y sistémico destinado a mejorar tanto a las empresas, como a los procesos y actividades que las conforman, y a los individuos que son los que las hacen realidad. El objetivo primero y fundamental es mejorar para dar al cliente o consumidor el mayor valor agregado.

• Katas: Código Kata es un intento de llevar este elemento de la práctica para el desarrollo de software que ayuda a un programador a perfeccionar sus habilidades a través de la práctica y la repetición.Un kata es un ejercicio de karate en la que repites una forma muchas, muchas veces, haciendo pequeñas mejoras en cada uno. La intención detrás de código kata es similar y el objetivo es la práctica, no la solución.

Deming. PDCA (plan–do–check–act )

3) CHECK Study the actual results (“DO”) and compare against the expected results ("PLAN"). Look for deviation in implementation from the plan and also look for the appropriateness and completeness of the plan to enable the execution.

4) ACT Request corrective action on significant differences between actual and planned results. Analyze the differences to determine their root causes. Determine where to apply changes that will include improvement of the process or product.

1) PLAN Establish the objectives and processes necessary to deliver results in accordance with the expected output

2) DO Implement the plan, make the product. Collect data for charting and analysis in the following steps.

Kaizen aplicado al SW: lean programming

• Lean programming is a concept that emphasizes optimizing efficiency and minimizing waste in the development of a computer program. The concept is that efficiencies can be applied and waste managed at all levels: each individual, every department, interdepartmental operations, the organization as a whole, and the relationships of the organization with customers and suppliers.

• Lean programming is based on rules that were developed by several corporations in the 1980s. The rules have an upbeat and positive tenor. For example, waste and intermediate artifacts should be kept to a minimum. Documentation should be concise, and should cover generalities without getting lost in details. Individual workers, as well as customers, should be consulted frequently, and their views and opinions taken seriously. A primary goal is continuous improvement at all levels and in all phases of the operation.

Kaizen aplicado al SW: refactoring

• Code refactoring is the process of restructuring existing computer code.

• Refactoring improves nonfunctional attributes of the software. Advantages include improved code readability and reduced complexity to improve source code maintainability, and create a more expressive internal architecture or object model to improve extensibility.
