Puntuación compuesta

Divide un juicio complejo en puntuaciones atómicas y combínalas con pesos que controlas en código.

A menudo queremos clasificar un conjunto de elementos según varios criterios a la vez. La puntuación compuesta es una forma sencilla de pensarlo: divide el juicio en dimensiones independientes, puntúa cada una por separado y combínalas con pesos que tú controlas en código.

Ejemplo: criba de currículos

Imagina que estás procesando currículos para puestos de ingeniería. Quieres clasificar a los candidatos según varios criterios y, en última instancia, seleccionar a los X mejores candidatos para una revisión posterior.

    subgraph req["TypeSafe evaluates questions<br/>in parallel"]

        py["<b>Score:</b> Python depth"]

    resume -- "one request<br/>resume + 4 questions" --> req
    req -- "one response<br/>4 score answers" --> normalize["<b>normalize scores to 0–1</b><br/>divide each by 4 in your code"]
    normalize --> ic["<b>senior IC weights</b><br/>40% Python + 10% leadership<br/>40% design + 10% generalist"]
    normalize --> em["<b>engineering manager weights</b><br/>15% Python + 40% leadership<br/>20% design + 25% generalist"]
    ic --> rank["rank candidates<br/>for each role"]
    em --> rank

Paso 1: puntúa cada dimensión de forma independiente

{
  "python_depth": {
    "type": "score",
    "instructions": "How much depth of python experience does this candidate have, based on the supplied resume?",
    "criteria": [
      "No Python experience mentioned",
      "Mentioned but no detail",
      "Used in projects, some specifics",
      "Primary language, multiple projects",
      "Deep expertise: architecture, performance, libraries"
    ]
  },
  "team_leadership": {
    "type": "score",
    "instructions": "How much experience does this candidate have managing or leading engineering teams?",
    "criteria": [
      "No management experience mentioned",
      "Informal mentorship or tech lead role",
      "Led a small team or project",
      "Managed a team with direct reports",
      "Managed multiple teams or an engineering org"
    ]
  },
  "system_design": {
    "type": "score",
    "instructions": "How much experience does this candidate have designing large-scale or distributed systems?",
    "criteria": [
      "No architecture work mentioned",
      "Contributed to design discussions",
      "Designed components of a larger system",
      "Owned architecture of a significant system",
      "Designed systems at scale across multiple domains"
    ]
  },
  "generalist": {
    "type": "score",
    "instructions": "How much evidence is there that this candidate picks up unfamiliar tools, roles, or domains outside their core specialty?",
    "criteria": [
      "Only one domain or role mentioned",
      "Some variety but within a narrow field",
      "Worked across a few different areas or tech stacks",
      "Regularly moved between domains, wore many hats",
      "Track record of ramping up in unfamiliar areas and delivering"
    ]
  }
}

Paso 2: combina con pesos

Cada dimensión se normaliza a 0–1 y se pondera. Los pesos te dan una forma sencilla de ajustar la importancia relativa de cada dimensión, sin perder nada de los matices de las puntuaciones individuales.

scoring.py

py      = response.answers["python_depth"].score / 4
lead    = response.answers["team_leadership"].score / 4
arch    = response.answers["system_design"].score / 4
general = response.answers["generalist"].score / 4

# Senior IC
ic_score = (0.40 * py) + (0.10 * lead) + (0.40 * arch) + (0.10 * general)

# Engineering Manager
em_score = (0.15 * py) + (0.40 * lead) + (0.20 * arch) + (0.25 * general)

Esto te da la capacidad de clasificar a los candidatos según la puntuación compuesta. Pero, más importante aún, te da visibilidad sobre cómo se calcula exactamente la puntuación final. Si los candidatos mejor clasificados no coinciden con tus expectativas, puedes ajustar los pesos para encontrar el equilibrio adecuado.
