Software Project Failure Analysis Based on Cost and Schedule Overruns

Abstract

Software project failure analysis is important because cost and schedule overruns remain major reasons for incomplete delivery, reduced quality, stakeholder dissatisfaction, and project cancellation. Software projects often exceed planned budgets and timelines due to unclear requirements, poor estimation, weak risk management, scope creep, resource shortages, technical complexity, communication gaps, and delayed decision-making. Traditional project evaluation may focus only on final delivery status, but this does not fully explain why overruns occurred or which project activities created the highest failure risk. This article focuses on software project failure analysis based on cost and schedule overruns by examining estimation errors, requirement changes, effort variance, milestone delays, productivity gaps, defect rework, and project control weaknesses. The study discusses how structured overrun analysis can help identify root causes, improve planning accuracy, strengthen monitoring practices, and support corrective decision-making in future projects. The article concludes that systematic failure analysis can reduce repeated project mistakes, improve budget and schedule control, support better risk management, and increase the probability of successful software delivery.
