\u00bfHabla SAFe de \u201cstory points\u201d?<\/strong><\/p>\n

Efectivamente SAFe sugiere m\u00e9todos para estimar el trabajo de los equipos.<\/p>\n

Los equipos \u00e1giles utilizan puntos de historia para estimar, y utilizan esta estimaci\u00f3n relativa para comparar una historia con otra. Parte de la labor de los equipos en una PI Planning, es calcular su capacidad para poder comprometer el alcance de sus entregas con el resto de los equipos<\/strong> involucrados en la implementaci\u00f3n<\/strong>, y de este modo, coordinar de manera conjunta la consecuci\u00f3n de los objetivos del PI.<\/p>\n

\u00bfC\u00f3mo utiliza SAFe los puntos de historia?<\/strong><\/p>\n

Estimar la capacidad del equipo en base a puntos de historia les ayudar\u00e1 a conocerse, a lograr una visi\u00f3n compartida del trabajo y a aprender de su propia velocidad de entrega de valor, de manera iterativa e incremental, tal y como se desarrollan los proyectos en los marcos \u00e1giles (i.e., Scrum). As\u00ed, pueden analizar cada historia considerando todas las variables a las que se enfrentan durante el desarrollo: su complejidad y su tama\u00f1o, la incertidumbre del entorno, las dificultades t\u00e9cnicas, los criterios de aceptaci\u00f3n o su verdadera disponibilidad (ausencias, vacaciones, formaciones, bajas m\u00e9dicas u otros compromisos previamente adquiridos). Utilizando su velocidad hist\u00f3rica como punto de partida, el equipo puede realizar los ajustes necesarios para determinar la capacidad real de la iteraci\u00f3n y comprometerse con convicci\u00f3n con los objetivos del PI, hasta donde considera que es capaz de llegar.<\/p>\n

\u00bfPara qu\u00e9 utiliza SAFe los puntos de historia?<\/strong><\/p>\n

Lo que SAFe denomina \u201cnormalizar\u201d<\/em> es que el punto de historia signifique lo mismo para todos los equipos, que la referencia base sea un tipo de historia similar para dar un valor de partida estimado parecido. Las velocidades de los equipos individuales ser\u00e1n singulares y depender\u00e1 de la realidad de cada equipo, pero es importante que todos usen la misma unidad de medida.<\/p>\n

El objetivo de esta \u201cnormalizaci\u00f3n\u201d<\/em> no es otro que escalar los puntos de historia a nivel de feature y\u00a0de las grandes funcionalidades del tren (ART), para poder as\u00ed determinar su velocidad. Esto ayuda al establecimiento de la capacidad del tren y de un criterio compartido sobre costes, pero nunca se debe utilizar para medir y comparar la eficiencia entre equipos.<\/p>\n

Otro caso en el que se habla de \u201cnormalizaci\u00f3n\u201d es en el que un equipo novel, sin hist\u00f3rico ni experiencia previa, o con un nivel a\u00fan bajo de madurez, puede iniciar sus estimaciones en base a las de otros equipos de caracter\u00edsticas similares, y cuya disponibilidad para el PI siguiente sea semejante.<\/p>\n

La estimaci\u00f3n es un mecanismo de comunicaci\u00f3n, una forma de establecer un di\u00e1logo y un compromiso en base a hechos hist\u00f3ricos. El equipo compara su trabajo en un PI con su propia ejecuci\u00f3n en PIs anteriores: es una herramienta del tren para el tren, de los equipos para los equipos<\/strong>. Utilizarla para comparar equipos entre ellos instar\u00eda a sus miembros a dedicar parte de su esfuerzo a la realizaci\u00f3n de un trabajo infructuoso, farragoso y bald\u00edo, desvirtuando el propio sentido de la estimaci\u00f3n y su utilidad para el equipo, y con una nula aportaci\u00f3n real de valor a la organizaci\u00f3n.<\/p>\n

Si la comparativa entre dos historias de dos equipos, estableciendo un punto de partida com\u00fan que permita orientar la velocidad y la asignaci\u00f3n de recursos econ\u00f3micos, deriva en la comparativa en t\u00e9rminos de eficiencia de cada uno de estos equipos, se convierte en un anti-patr\u00f3n ligado m\u00e1s a las personas y roles, que a las prescripciones del marco de trabajo en s\u00ed. Lamentablemente es com\u00fan en transformaciones que, utilizando SAFe como bandera, se personalizan o se construyen desde la inexperiencia o el desconocimiento, y sin tener en cuenta el principal sustento de cualquier transformaci\u00f3n \u00e1gil, lo que garantiza, a largo plazo, la coherencia, la solidez y la sostenibilidad de la transformaci\u00f3n: los principios y valores \u00e1giles.<\/strong><\/p>\n<\/div>
