Beliefs Impacting Budget Overruns in Software Development

February 9th, 2024
Software Development Beliefs That Impact Your Budget.


In software development, certain beliefs can contribute to budget overruns. Unraveling these myths is essential for successful project management. Some of the common beliefs are:

  • Comprehensive Planning Solves Everything

  • Shortcuts Save Time and Money

  • Changes Won't Happen

  • We Can Handle Everything Internally

  • Our Team Doesn't Need Additional Resources

Embrace outsourcing to professionals for comprehensive planning, quality assurance, effective risk management, efficient resource allocation, and proactive problem-solving. Break free from false beliefs and ensure budget-friendly software development. Hiring remote developers means: 

  • Comprehensive Planning

  • Quality Assurance

  • Effective Risk Management

  • Efficient Resource Allocation

  • Proactive Problem-Solving


Software development is a complex process that involves many uncertainties. One of the most common problems software projects face is budget overruns. This occurs when the cost of developing a software product exceeds the initial cost. 

Several factors contribute to cost overrun in software development. This includes changing requirements, technical difficulties, and poor estimation. Unrealistic expectations and scope creep play a role in the increase in the cost. Lack of communication, and inadequate testing are some of the other factors.

These issues often lead to beliefs and myths affecting software development. This article explores the common assumptions that spawn while attempting to counter the problems of a project. These beliefs eventually cause cost overruns as well. 

Common Beliefs

Belief #1: The more features, the better:

The more features, the better.

This is one belief that can lead to cost overrun. This means that adding more features to a software product will make it more valuable and attractive. This belief can result in feature creep. Feature creep is the tendency to keep adding new features to a software product during its development. 

Always consider the impact it will have on the cost and schedule. Feature creep will most likely increase your costs. The reason is the increase in the complexity and scope of the project. This usually requires more resources, time, and testing. 

Avoid feature creep and its consequences by focusing on delivering features in the initial plan. Opting for a minimum viable product (MVP Development) is also a good solution. Spend time and effort creating the initial feature list. 

For an MVP, prepare a clear list of requirements that align with the project goals and user needs. The MVP should consider feedback from real users and customers. This will ensure it meets their expectations and provides value.

Add the additional feature only after validating the MVP. Assessing their impact on the product's cost, schedule, quality, and usability.

Belief #2: Initial project plan is final

Initial project plan is final.

A typical software development belief is that the plan for a software project is final. This means that changes or deviations from the plan are not possible. 

This belief will result in the need to be more rigid about the development approach. The waterfall model is one such approach for software development. This follows a linear and sequential process that consists of distinct phases. The phases include requirements, design, implementation, testing, deployment, and maintenance. 

This will cause cost overrun. Do not assume all the specifications for a software product are known. It also assumes they are stable.

This is on the basis of the planning at the initial stages of the project. It typically ignores uncertainties and changes in the software development process. Delays feedback and testing until the late stages of the project.

Belief 3: Project management tools not necessary: 

Project management tools not necessary.

The belief that tools are not necessary contributes to budget overruns in several ways:

  • Communication issue: You may miss important information without centralized communication channels. Mistakes in communication and delays can lead to project setbacks, potentially causing budget overrun.

  • Lack of Real-time Visibility: Without real-time visibility into project progress by project management tools, decision-makers may lack timely insights. Delays in identifying issues can lead to an increase in costs.

  • Limited Collaboration: Project management tools facilitate seamless collaboration, task tracking, and resource allocation. The absence of such tools may hinder efficient teamwork, potentially causing bottlenecks and project delays.

  • Ineffective Task Management: Dedicated tools offer task tracking, assignment, and progress monitoring features. These tools are necessary for task management to become efficient, leading to overlooked tasks and project timeline extensions.

  • Scope Creep knowledge: Project management tools assist in defining and monitoring project scope. These tools are necessary to detect scope changes. This increases workloads, and potential budget overruns.

  • Poor Resource Allocation: Tools provide insights into team availability and workloads, helping allocate strategic resources. Resource conflicts may arise without such tools, causing delays and increase in costs.

  • Risk Management Oversight: Project management tools often include risk identification, assessment, and mitigation planning features. The absence of these tools may result in inadequate risk management, leading to unforeseen challenges and potential cost overruns.

  • Limited Time Tracking: Specialized project management tools often include time tracking features. These are essential for tracking project progress and managing billable hours. In their absence, accurate time monitoring may become challenging, affecting project timelines and budgets.

Tools play a vital role irrespective of the project size. They address the challenges in the list above and mitigate the risk of budget overruns. They enhance communication, collaboration, and overall project efficiency.

The right tools can contribute significantly to project success. The features of such tools include real-time insights, task management, resource allocation, risk management, and much more.

Belief #4: The development team can handle changes & scope creep:

The development team can handle changes & scope creep.

This is a false belief and leads to increase in cost:

  • Wrong estimation of Impact: Changes, especially those introduced without proper assessment, can lead to additional work. This increases development time and unexpected costs.

  • Issue with goals: Without clear vision, changes may disrupt the workflow. This leads to delays in critical tasks and potential budget overrun.

  • Inadequate Communication: Poor communication can result in confusion and missed requirements. Subsequently rework leads to increase in costs and project delays.

  • Absence of Change Control: Lack of change control can result in unmanaged scope creep, making it challenging to track and control changes. This can lead to scope expansion without corresponding budget adjustments.

  • Scope Creep:  Scope creep can considerably increase work. This affects project timelines and causes cost overruns over time.

  • Resource Strain: Only introducing changes while assessing resource availability can lead to overburdened team members. This often causes burnout and compromises productivity. This will, in turn, impact the project budget.

  • Unmanaged Dependencies: Changes can introduce unforeseen dependencies, causing delays in tasks with dependencies. Failure to manage these dependencies can result in project bottlenecks and increased costs.

  • Quality Compromises: Rushing implementations to accommodate changes may result in decreased quality. This leads to the need for rework and potential budget overruns to address quality issues.

  • Ineffective Risk Management: Changes introduced without a proper risk assessment may lead to unforeseen challenges and disruptions. This will make it hard to tackle the increase in costs. Proactive risk management can simplify this process.

Implement a robust change management process to mitigate the impact of changes. This type of change management process needs to assess the effects of the changes. It also accounts for them as per the budget and timeline constraints.

Belief #5: Additional effort is not necessary for complex projects:

Additional effort is not necessary for complex projects.

The belief that additional effort is not necessary for complex projects can contribute to cost overruns in various ways:

  • High Complexity: Complex projects often involve unforeseen challenges and intricacies. Failing to recognize the full extent of complexity can lead to miss judging the efforts and cost overrun.

  • Lack of Detailed Planning: Detailed planning is crucial for understanding the intricacies of complex tasks. The lack of this leads to issues with functions. It also increases the effort necessary and potential budget overruns.

  • Absence of Risk Assessment: Complex projects often mean higher risks. With a failure to identify and address potential risks, projects may encounter unforeseen challenges. This causes delays and increases costs.

  • Inadequate Contingency Planning: Complex projects are more prone to uncertainties. Lack of sufficient contingency reserve will result in such challenges to strain the budget.

  • Failure to Anticipate Dependencies: Complex projects typically involve multiple tasks. Expecting and managing dependencies can result in delays, rework, and increased costs.

  • Scope Misalignment: As complexities emerge, project scope may need adjustments. Ignoring the need for scope realignment can lead to scope creep. This will eventually increase workloads and cause cost overruns.

  • Resource estimation issue: Complex projects may require special skill resources. Issues with estimating resource needs can lead to teams needing to work overtime. This decreases their efficiency and increases the chances of cost overruns.

  • Depending too much on Technology: Human expertise is crucial for navigating complex tasks and surpassing technology. More reliance on technology leads to oversights and increased costs.

  • Ineffective Change Management: Changes in complex projects will have a ripple effect. Failing to manage changes effectively can result in the need for additional effort. It means rework and cost overruns.

To avoid budget overruns in complex projects, embrace realistic planning. Conduct thorough risk assessments, allocate sufficient contingency reserves, and remain adaptable to changes. Recognizing the need for additional effort and resources in the face of project complexity.

Belief #6: Same factors & issues affect all projects:

Same factors & issues affect all projects.

The belief that the same factors and issues affect all projects can contribute to cost overruns in various ways:

  • One-Size-Fits-All Planning: Each project is unique; hence, adopting a generic planning approach is a mistake. This leads to the project manager needing to pay more attention to details.

  • Failure to Account for Uniqueness of Project: Projects with apparent similarities can have subtle differences. Failing to account for the unique elements can be disastrous.

  • Neglecting Industry-Specific Challenges: Different industries may have unique challenges. Neglecting industry-specific considerations can result in inadequate risk assessment and budget planning.

  • Overlooking Stakeholder Dynamics: Stakeholder engagement and expectations vary across projects. Ignoring these differences will misalign the priorities and cause issues. This increases your project expenses as well.

  • Ignoring Project Lifecycle Differences: Projects may follow different methodologies and lifecycles. Please incorporate these unique elements during the estimation to avoid bad planning and budget overruns.

  • Inadequate Risk Assessment: Each project comes with its own set of risks. Neglecting project-specific risk assessment can lead to unforeseen challenges and an increase in costs.

  • Project Complexity Issue: Projects can vary significantly in complexity. Higher complexity means you need to pay more attention to the details. This needs more effort and causes cost overruns.

  • Cookie-Cutter Resource Allocation: Projects may require different skill sets and resource allocations. Using a one-size-fits-all resource allocation model can result in issues and increase costs.

  • Neglecting Environmental Influences: External factors such as market conditions or regulatory changes can affect different projects differently. Neglecting these influences can lead to budget overrun.

Belief #7: Risk assessment is not necessary:

Risk assessment is not necessary.

The belief that risk assessment is not necessary can contribute to cost overruns in several ways:

  • Unknown Threats: Without a systematic risk assessment, there is a higher likelihood of overlooking potential threats to the project. Unknown risks may come up, leading to unexpected challenges and increases in costs. 

  • Absence of Contingency Planning: Lack of contingency planning leaves the project vulnerable to unforeseen events. When risks come up, the absence of a backup plan can lead to budget overrun.

  • Failure to Prioritize Risks: Lack of this will lead to inefficient resource allocation. The critical risks will need more resources for you to address them. High-impact risks that come up can lead to budget overruns.

  • No Contingency Execution: The absence of a contingency plan can delay the response. Quick, decisive actions are crucial when mitigating risks to prevent budget overruns.

  • Scope Creep from Unmanaged Risks: It can lead to changes in project scope as teams react to unforeseen challenges. Scope creep can result in additional work, extended timelines, and increase in costs.

  • Inadequate Resource Allocation: Risks may require additional resources for mitigation. Without a proper assessment, resource shortages can occur. This will impact project efficiency and lead to budget overrun. 

  • Overlooking External Influences: External influences, such as market changes or regulatory shifts, pose risks. Failure to assess and address these external factors may lead to unforeseen costs. 

  • Ineffective Risk Monitoring: Risks can evolve over the project lifecycle. New risks may emerge without active monitoring, and previously identified risks may escalate, leading to budget overrun. 

  • Poor Stakeholder Management: Risks can affect project timelines and delivery. This leads to issues among stakeholders. Poor stakeholder management may cause an increase in project costs and cost overrun. 

  • Cumulative Risk Impact: Individual risks may seem minor, but their cumulative effect can be substantial.

To avoid cost overruns, acknowledge the necessity of thorough risk assessment and develop contingency plans. Actively monitor and manage risks throughout the project lifecycle. A proactive approach to risk management is essential for project success and financial control.

Belief #8: A fixed-bid contract means there will be no changes:

A fixed-bid contract means there will be no changes.

The belief that a fixed-bid contract means there will be no changes can contribute to cost overruns in several ways:

  • Scope Creep: Project scopes evolve with unforeseen circumstances. Client requests, or changes in project requirements are also other issues that cause this. Inadequate management of these changes is never good. They can lead to scope creep and additional work, causing cost overruns.

  • Limited Flexibility for Changes: Clients may have legitimate reasons for requesting changes. With a mechanism for managing change requests, the project may avoid resistance. Failure to make adjustments can lead to budget overruns.

  • Inadequate Change Control: Lack of proper change control mechanisms will lead to haphazard project development. This disrupts the workflow and causes budget overrun.

  • Client Expectation Misalignment: Clients may have evolving needs or need to comprehend a fixed-bid agreement's constraints fully. If client expectations have flaws, requests for changes may arise, impacting the project budget.

  • Risk of Assumed Stability: Changes in project requirements and other external factors often affect the project. Please account for these changes to avoid cost overruns.

  • Unforeseen Challenges: Challenges, such as technical or unexpected obstacles, can emerge during the project. Additional effort and resources may be necessary. This happens when there is no flexibility to address these challenges.

  • Resistance to Adaptation: Resistance to necessary adaptations can hinder the project's ability. Failure to respond effectively to changing circumstances causes budget overruns.

  • Limited Contingency Planning: Even in fixed-bid contracts, having a contingency reserve for unexpected challenges is prudent. Always include a buffer to ensure the project is safe from unforeseen expenses resulting in cost overrun.

Establishing clear change management processes is essential to mitigate the risk of budget overrun in fixed-bid contracts. Always maintain open communication with clients and educate stakeholders about the limitations of fixed-bid arrangements. Incorporate contingency planning to address unexpected challenges. 

Belief #9: Small changes do not cause cost overruns:

Small changes do not cause cost overruns.

The belief that small changes do not cause cost overruns can contribute to cost overruns in various ways:

  • Changes: Each small change may seem minor. The cumulative effect of several small changes will result in a substantial increase in work. This causes delays and budget overruns.

  • Scope Creep Oversight: Small changes often contribute to scope creep. As the project scope expands slowly it requires additional effort and resources.

  • Effort estimation issue: Small changes may involve hidden complexities or dependencies that were initially absent. With more effort required for minor changes, it can lead to greater costs.

  • Resource Strain: Even small changes can strain resources. This is more true if the project team already operates at full capacity. Shortages of resources lead to delays.

  • Lack of Change Control: A lack of change control mechanisms leads to making small changes without assessing their impact. This lack of control can result in disruptions and increase the workload.

  • Client Expectation Misalignment: Clients may have expectations about project timelines and costs. Failure to manage client expectations regarding small changes can lead to potential disputes.

  • Inadequate Time Tracking: With accurate time tracking, the true impact of small changes will register with the team. This will end up increasing the project time and catching the team off-guard.

  • Quality Compromises: Implementing small changes in an ad hoc manner compromises quality. Addressing quality issues, post-implementation can result in additional work and increased costs.

  • Failure to Communicate Changes: Lack of communication can lead to misalignment. This can result in rework, delays, and potential cost overrun.

To mitigate the impact of small changes on cost overruns, implement effective change management processes. Communicate transparently with stakeholders and track time and resources.. Assess the impact of each change, regardless of its size. Recognizing the potential cumulative effect of small changes is essential for maintaining financial control and successful project delivery.

Belief #10: External factors do not affect your project:

External factors do not affect your project.

The belief that external factors do not involve a project can contribute to budget overrun in various ways:

  • Market Changes: External market changes can be shifts in demand, supply chain disruptions, or economic fluctuations. They can affect project costs and timelines. Ignoring these factors may lead to unforeseen expenses.

  • Regulatory Changes: Changes in regulations or compliance requirements affect the project plan. Failure to anticipate and adapt to regulatory changes increases costs.

  • Technological Advancements: Rapid technological advancements can affect your project. It can render the current technologies obsolete or necessitate updates. Ignoring this will mean developing a substandard product or increasing the cost. 

  • Supplier or Vendor Issues: Supplier or vendor issues include delays, quality issues, or disruptions. This affects the project timelines and costs. Always account for these external dependencies to avoid budget overruns.

  • Currency Fluctuations: Currency fluctuations can significantly impact budgetary estimates if the project involves international transactions. Failing to account for this leads to unexpected expenses.

  • Natural Disasters or Events: Unforeseen events, such as natural disasters, can disrupt project activities and delay deliveries. This is likely to add to the initial costs.

  • Political issues: Political changes, unrest, or issues in the project region can affect project timelines and costs. This can affect your project in many ways.

  • Global Economic Conditions: Economic downturns or recessions can impact project funding, client budgets, and overall project. Ignoring global economic conditions may lead to financial challenges and budget overrun.

  • Public Health Emergencies: Events like pandemics can disrupt project workflows. Limits resource availability and increases project costs. Ignoring the potential for public health emergencies may result in cost overruns.

  • Changes in Client Priorities: Changes in client priorities or preferences during the project may lead to additional work, revisions, and increased costs. Failing to adapt to evolving client needs often means cost overrun.

Conduct a risk assessment for the external factors to mitigate the budget risk. Besides this, it also monitors relevant external factors regularly. This proactive approach will help your business deal with unknown external factors correctly. 

Belief #11: Contingency budget or plan is not for you:

Contingency budget or plan is not for you.

The belief that a contingency budget or strategy is not necessary can contribute to cost overruns in various ways:

  • Failure to Anticipate Unknown Unknowns: Projects inherently involve the unknowns and uncertainties. A contingency budget can be invaluable in this case. 

  • Project Complexity Issue: Even seemingly simple projects can encounter complexities. With a contingency plan, the project may succeed.

  • Initial Estimates Issues: Over-reliance on initial estimates without a contingency plan may lead to cost overruns.

  • Scope Changes Without Adjusting Budget: Changes in project scope, irrespective of the reason, mean higher workload and cost. This is where a contingency budget can help. 

  • Neglecting External Factors: External factors affect project costs. This is hard to manage without any contingency plan.

  • Absence of Risk Mitigation Measures: Proactive risk mitigation is essential to avoid budget overruns. 

  • Inadequate Resource Planning: Unforeseen challenges may require additional resources. With a contingency plan, this is easier to archive.

  • Client Expectation Misalignment: Client expectations may evolve during the project, leading to change requests. Lack of an alternative plan will leave you stranded.

These factors help you realize the value of a contingency budget. Without any proactive measures your project will spell disaster.

Belief #12: Comprehensive upfront planning ensures project success:

The belief that comprehensive upfront planning ensures project success can contribute to budget overrun in various ways. Assuming that comprehensive upfront planning can accurately predict all project variables and outcomes.

Predicting the precise change requests and scope changes is tough. Wrongly estimating the risks is quite common too. All these factors can cause the expenses to rise. 

Belief #13: Shortcuts save time and money:

The belief that shortcuts save time and money can contribute to cost overruns in various ways. It often means compromising on quality, inefficient planning, and more rework. This can also lead to an increase in technical debt and client issues. Shortcuts may seem expedient in the short term, but they are never the solution in the long term.
