Project Development

Project Development is a community skill for managing the full lifecycle of software projects from initial planning through delivery, covering architecture decisions, task breakdown, iterative implementation workflows, and delivery verification against acceptance criteria.

What Is This?

Overview

Project Development provides structured workflows for taking a software idea from concept to working product. It covers requirements gathering, architecture design, milestone planning, implementation sequencing, and delivery verification. The skill emphasizes practical patterns that work across team sizes rather than prescribing a single methodology.

Who Should Use This

This skill serves solo developers managing personal projects, team leads planning sprints and milestones, and engineers who need systematic approaches to building features that span multiple files and components.

Why Use It?

Problems It Solves

Projects stall when developers jump into code without clear requirements or architecture direction. Scope creep occurs when goals are not documented upfront with boundaries. Integration problems surface late when components are built in isolation without interface contracts. Teams waste effort building features that do not align with actual user needs because requirements were never validated.

Core Highlights

Requirements templates capture functional and non-functional needs before coding begins. Architecture decision records preserve the reasoning behind technical choices for future reference. Milestone decomposition breaks large goals into verifiable increments with clear acceptance criteria. Dependency mapping identifies the correct build order across system components.

How to Use It?

Basic Usage

from dataclasses import dataclass, field
from enum import Enum

class TaskStatus(Enum):
    PLANNED = "planned"
    IN_PROGRESS = "in_progress"
    DONE = "done"
    BLOCKED = "blocked"

@dataclass
class Task:
    title: str
    status: TaskStatus = TaskStatus.PLANNED
    dependencies: list[str] = field(default_factory=list)
    acceptance_criteria: list[str] = field(default_factory=list)

@dataclass
class Milestone:
    name: str
    tasks: list[Task] = field(default_factory=list)

    def progress(self) -> float:
        if not self.tasks:
            return 0.0
        done = sum(1 for t in self.tasks if t.status == TaskStatus.DONE)
        return done / len(self.tasks)

    def next_available(self) -> list[Task]:
        done_titles = {t.title for t in self.tasks if t.status == TaskStatus.DONE}
        return [
            t for t in self.tasks
            if t.status == TaskStatus.PLANNED
            and all(d in done_titles for d in t.dependencies)
        ]

Real-World Examples

class ProjectPlan:
    def __init__(self, name: str):
        self.name = name
        self.milestones: list[Milestone] = []
        self.decisions: list[dict] = []

    def add_decision(self, title: str, context: str, choice: str):
        self.decisions.append({
            "title": title,
            "context": context,
            "decision": choice
        })

    def summary(self) -> str:
        lines = [f"Project: {self.name}"]
        for ms in self.milestones:
            pct = ms.progress() * 100
            lines.append(f"  {ms.name}: {pct:.0f}% complete")
            for task in ms.next_available():
                lines.append(f"    Ready: {task.title}")
        return "\n".join(lines)

plan = ProjectPlan("API Service")
m1 = Milestone("Foundation", [
    Task("Set up repository", TaskStatus.DONE),
    Task("Define database schema", dependencies=["Set up repository"]),
    Task("Build API endpoints", dependencies=["Define database schema"]),
])
plan.milestones.append(m1)
print(plan.summary())

Advanced Tips

Record architecture decisions as they happen rather than reconstructing them afterward. Review milestone progress weekly and adjust scope based on actual velocity measurements. Keep acceptance criteria specific and testable so reviewers can verify completion without subjective judgment.

When to Use It?

Use Cases

Plan a new application from scratch with clear milestones and delivery targets. Coordinate feature development across frontend and backend teams using shared task boards. Break down a large refactoring effort into safe, incremental steps that keep the system deployable throughout.

Important Notes

Requirements

A version control system for tracking code changes, a task management tool or structured document for milestone tracking, team agreement on review and approval processes, and a communication channel for surfacing blockers quickly.

Usage Recommendations

Do: define acceptance criteria before starting implementation on each task. Update project plans as requirements evolve rather than working from stale documents. Ship working increments frequently to gather feedback early.

Don't: plan every implementation detail months in advance when requirements remain uncertain. Skip architecture discussions for projects involving multiple developers or services. Treat the initial plan as immutable when new information emerges.

Limitations

Planning templates cannot substitute for domain expertise needed to make architecture decisions. Task dependency tracking adds overhead that may not benefit very small projects. Milestone estimates remain inherently uncertain regardless of how detailed the task breakdown becomes. Plans work best as living documents that evolve with the project rather than fixed contracts.
