What are the most common causes of project budget overruns and how to avoid them?

1.Poor Scope Definition 2.Inaccurate Estimations 3.Changes in Project Requirements 4.Inadequate Project Management 5.Poor Cost Control 6.Failure to Learn from Past Projects

It is never just 1 factor, but usually a combination. Somehow I find that it usually can be attributed to the upfront analysis and planning, and ability to revise along the way, that is to blame. Not to advocate for a full waterfall approach, but taking the time to properly define the purpose and managing both functional and non-functional expectations up-front is time well spent.. Measure twice - cut once. Of course "the best laid plans of mice and men often go awry", so revisiting assumptions and plans along the way is a must for ensuring the ship doesn't veer off course too much.

Projects are often subject to cost overruns due to a variety of factors, such as poor estimation techniques or assumptions, scope creep or change requests, inadequate contingency or reserve funds, unforeseen risks or uncertainties, inflation or currency fluctuations, delays or rework, resource shortages

Projects often leads to over run because of poor requirement gathering from project stakeholders Missing stakeholders mapping which leads to scope not added during initial requirement gathering stage Scope not defined properly or poorly written scope by Project Manager No Change control mechanism or poorly managed Change control process Unsigned or unapproved requirement documentation with client signatories

Project budget overruns are often rooted in inadequate planning, scope changes, and unforeseen risks. In my experience, a meticulous initial plan, continuous risk assessment, and transparent communication can significantly mitigate these challenges. Emphasizing adaptability and fostering a culture of accountability also play crucial roles in keeping projects on budget. Looking forward to hearing more insights from the community on this vital topic.

As long as scope is well defined and changes are assessed with regard to impacts, the over runs can be managed and where necessary the scope cut back when over runs nears critical.

The key point to avoid Scope Creep is starts by setting clear, realistic expectations at the project's outset, followed by monitoring to ensure alignment with those expectations, and if not, allowing for necessary adjustments during the execution. In essence, it's all about making sure that what you initially planned matches the actual progress and results, ultimately ensuring a successful project outcome.

I would suggest a lack of early contractor involvement and interdisciplinary input and knowledge sharing at the “preferred option selection” and initial design phase has potential to lead you to later scope creep issues.

- Poor coordination and communication - Unclear and not so detailed scope - No standard procedures for variation orders - Poor project management - Over enthusiastic staff to please client :-)

Ranked in order: 1) scope definition 2) change control 3) continuous monitoring 4) risk management A dangerous condition is created when contract types used are not suitable for project conditions.

This is, in my opinion, the main cause of project overrun or at least the main starting cause. If you fail to plan, you plan to fail. This is not only valid for Planning but also Cost. A good Cost Estimate or Proposal done with the right methodology/level of details and properly documented will put you on the right track. Poor estimation from lack of expertise, experience, or information could be mitigated with proper Cost Estimation methodology (Cost Risk Analysis, Contingencies). Poor estimation from optimism bias, cognitive bias, or pressure from management or clients is hard to recover and usually lead to disaster.

From my experience as a Project Accountant for the Project Management team, lots of unnecessary rework and lost revenue occurred due to not having the right information in a timely manner in order to invoice the customer correctly. In other words, we send an invoice to the customer but this invoice did not contain all the actual work/money we should have charged them. Upon reflection, my thoughts were that it was either because the PM team did not have time to send me all the documents to get on the invoices, or they operated at a higher level in terms of just get the invoices out even if we're undercharging and focus on volume.

In my opinion poor estimation is a common cause of project budget overruns and occurs when initial project cost assessments are inaccurate. This can stem from various factors such as insufficient data, lack of experience in similar projects, or overly optimistic assumptions. When project costs are underestimated, it often leads to budget overruns as the actual expenses exceed the initially projected budget.

The key factor in risk assessment is to evaluate risk register periodically and update as the time progresses. Taking expert opinion at every project stage to update, add or remove risks would help keep the assessment current and avoid last minute surprises that eventually lead to many factors that can affect project outcomes or worse failures.

Producing poor quality work is one of the most common reasons for budget overruns. Poor quality work leads to delay due to redoing the task to fix it and match with acceptable quality standards per specs. The sooner defects are identified, the lesser it would cost to fix it, and vice versa.

I would say that one way to prevent inadequate communication, it’s essential to exercise strong leadership skills. Start by crafting a communication strategy that outlines your communication goals, the methods to be used, the frequency of updates, and the roles and responsibilities of each team member. It’s crucial to ensure that your messages are not only transparent, concise, and uniform but also to foster an environment where everyone is encouraged to communicate openly, honestly, and in a supportive manner.

This is a sticky point and the most ambiguous one, as stakeholders can come from the same or all different organizations and backgrounds. Differences in ERP systems, communication tools, and even accounting practices can complicate the effectiveness of such communications. Project manager needs to play an active role to set goals and benchmarks throughout the project cycle, so as to coordinate and manage the dynamics of communications process.

1. Underestimating the time and cost of resources 2. Inefficient or incompetent staff. 3. Too optimistic budget 4. Unrealistic goal setting 5. failing to keep regular tabs on performance and progress.

In my experience, underspending is more common than overspending, mainly because if you don't have a proper finance management process in place, colleagues who can authorise expenditures don't always have reliable data to understand the financial situation of their project. In the face of uncertainty, colleagues will not spend to avoid having to explain potential overspending to their manager.

Projects overrun budget because they lack leadership from the outset. Objective goals must be defined first. Organizations turn leadership into management; allowing the executors of a project to define the goals. Those goals will be attainable and highly unimportant. Then, execution of the wrong tasks, executed well, are held out as victories. They're not; they're still the wrong tasks. They re measured in detail, but no one is watching the shop. Leaders must take complete ownership of a project's goals and outcomes. You are not implementing an ERP system. You are delivering a tool by which measurement of detailed activity is automated and simply aggregated to improve business outcomes. Successful projects begin and end with leadership.
