DependencyBot: Microsoft Project Bulk Predecessor Importer

A lightweight Microsoft Project add-in that reads dependency rules from a structured CSV/Excel template (task_id, predecessor_id, lag_days, dependency_type) and applies all relationships in a single batch operation. Users define rules once, upload the file, and the plugin validates against existing tasks, then mass-links predecessors in seconds instead of hours of manual clicking.

PLUGIN

15 weeks • 70% confidence

Value Proposition

Eliminates 80% of manual dependency-linking time by batch-applying rules; catches missed dependencies through validation; works natively inside Microsoft Project (no context-switching); cheaper and faster than hiring a project coordinator to do it manually

Target Audience

Enterprise project managers and PMOs using Microsoft Project with 100+ task projects; construction, engineering, pharma, and manufacturing firms managing complex schedules

Key Features

  • CSV/Excel upload with task_id, predecessor_id, lag, dependency_type (FS/SS/FF/SF) columns
  • Pre-import validation that flags missing tasks, circular dependencies, and conflicts
  • Undo/rollback if batch application creates errors
  • And more, with full implementation detail...

Tech Stack

Microsoft Project COM/VSTO (Visual Studio Tools for Office) C# or VB.NET for add-in development Office Fluent XML for ribbon UI CSV/Excel parsing library (CsvHelper, EPPlus, or ClosedXML)

Original Problem

Project managers waste hours manually setting task dependencies in Microsoft Project instead of bulk-applying predecessor relationships

Project managers using Microsoft Project struggle to efficiently establish predecessor relationships across multiple tasks, forcing them to manually link tasks one-by-one rather than applying batch dependency rules. This repetitive, time-consuming process delays project planning and increases the likelihood of missed dependencies, especially in complex projects with hundreds of tasks. Current Microsoft Project UI lacks a native bulk predecessor assignment feature, leaving managers stuck with inefficient workarounds.
