The hidden costs of DIY PPM implementation: common pitfalls and how to avoid them

After months of frustration with outdated project management tools, you finally decided to make the switch to a more robust, modern, and comprehensive PPM solution. The search was on.

You scoured the entire PPM vendor landscape, researched thoroughly, gathered team feedback, defined evaluation criteria, and weighed your options carefully. Finally, you found what looked like the perfect PPM solution. It promised everything: advanced resource management and project tracking, strategic alignment, comprehensive reporting, and AI capabilities.

At Virelli, we understand this journey all too well. With more than 1,000 implementations behind our team, we have seen firsthand the challenges and pitfalls that come with DIY PPM projects.

Your team successfully implemented the PPM solution in-house, and you were all set to transform the project portfolio management landscape for good.

PPM sets sail and the journey is smooth, until it wasn't

The ship finally set sail, and the team was excited. Everything ran smoothly until the first wave hit the deck, and cracks started to appear.

The new tool did not integrate well with your old systems, and customization was challenging. Small issues arose: data was inconsistent, and the analytics were off. Resource problems drove up costs, slowed productivity, and pushed deadlines back.

The key to overcoming these hurdles lies in anticipating them!

If you are considering a DIY PPM implementation and have not experienced these challenges yet, that's great news! It means you still have time to prevent the above from happening. Today, we will help you do just that.

In this blog, we outline the most common pitfalls DIY implementations encounter (and fall prey to). Then, we provide strategies to help you make quick course corrections at the implementation level that can help mitigate their impact. Read on:

What are the hidden costs of a DIY PPM implementation?

The costs that hurt most rarely show up in the project budget. The license and go-live date look fine on paper. The real costs build over the months that follow:

• Internal time: The people configuring the tool are usually also running projects, so both the implementation and their day jobs slow down.
• Rework: Configuration built on assumptions, or left at the defaults, often has to be redone once real teams start using it.
• Data cleanup: Resource, project and financial data that isn't cleaned and mapped before migration produces reports nobody trusts.
• Low adoption: When the tool doesn't match how people work, teams keep their spreadsheets, and the PPM system becomes one more place to update.
• Delayed value: Leaders still make portfolio decisions without reliable data, the problem the tool was bought to solve.

Often the organization ends up bringing in outside help anyway, to fix what could have been set up right the first time.

Four common pitfalls and ways to avoid them

Common pitfall #1: resource allocation and utilization problems

Resource allocation and utilization problems are often the first warning signs of poorly constructed PPM implementations. In a DIY implementation, this usually traces back to resource data that was migrated as is, or resource management features that were never configured.

Resource issues become apparent when overburdened teams struggle to meet deadlines. Lack of productivity and resource constraints can quickly degrade project quality, delay project timelines, or even cancel projects. Adding additional resources is often the automatic response, but it is counterproductive, increasing costs and creating new imbalances.

Ways to avoid resource allocation and utilization problems

• Resource Capacity Planning: Thoroughly evaluate resource capacity to assess the organization's ability to handle project requirements (current and future).
• Improved Resource Allocation Methodology: Define a clear and consistent guideline for resource allocation, focusing on skill sets, workload, and project priorities.
• Standard Resource Utilization Metrics: Establish clear and concise KPIs to measure resource utilization and accurately identify areas of optimization.
• Accurate Resource Data Migration & Cleansing: Ensure accurate and comprehensive data migration of resource information, including certifications, skills, and availability.

Common pitfall #2: uncontrolled project growth

Uncontrolled project growth is a slow burn that may seem harmless initially but eventually grows into a smoldering heat that ignites a fire.

While the projected growth may seem ideal initially, the momentum soon spirals into a tangled mess that cannot be controlled or managed. Resource constraints, cost overruns, increased errors, and reduced agility are common symptoms of uncontrolled growth, which, over time, chokes and derails portfolio management.

Weak project selection criteria and insufficient portfolio oversight are two primary reasons for uncontrolled project growth. The absence of formal approval processes and the lack or bypass of rigorous evaluation further exacerbate the problem and accelerate the expansion. DIY rollouts often skip configuring intake and approval workflows, so the tool records projects without helping anyone decide which ones should start.

Ways to avoid uncontrolled project growth

• Set A Robust Project Intake Process: Define clear and explicit project initiation criteria, prioritize based on strategic alignment and ROI, and establish a formal approval process with designated decision-makers to prevent uncontrolled growth.
• Ensure Strategic Alignment: Continuously assessing ongoing projects for strategic alignment keeps resources focused on high-value work. See how one education nonprofit connected every project to its mission.
• Focus on Project Closure: Enforce standard project closure procedures to prevent zombie projects and release resources for new initiatives.
• Enhance Resource Allocation: Leverage appropriate PPM tools and customize them to meet resource allocation needs. Regular portfolio assessments that balance workloads and proactive resource estimation prevent resource over-commitment.

Common pitfall #3: delayed decision-making

Inconsistent data formats, poor data quality, standardized reporting gaps, and slow data processing often lead to decision-making delays, which is a competitive disadvantage today. When reports and dashboards aren't designed around the decisions leaders need to make, people go back to exporting data into spreadsheets.

Decisions based on intuition rather than data trigger second-order problems that lead to suboptimal resource allocation, missed opportunities, and increased project risk. Delayed decision-making also drives up project costs (resource inefficiencies) and reduces an organization's ability to adapt to market changes.

Ways to avoid delayed decision-making

• Improved Data Quality and Accessibility: Ensure data consistency through integration and standardization, followed by rigorous data cleansing. A centralized repository offering real-time access to accurate information is critical.
• Decision-making Frameworks: Establish a structured decision-making framework with defined roles and responsibilities. Cultivating a data-driven culture and implementing a robust decision-making framework are foundational for efficient data-driven decision-making.
• Enhanced Reporting and Analytics: Leverage predictive analytics to complement real-time reporting. Standardized reports paired with dynamic visualizations can significantly accelerate decision-making processes.

Common pitfall #4: low user adoption

A PPM tool only works when people use it. Go-live is a technical milestone, not proof of success, and adoption problems often surface months later, when project managers update the system once a month and teams quietly keep their own spreadsheets.

DIY implementations are especially exposed here, because training tends to cover the tool's features rather than how each role should use it day to day.

Ways to avoid low user adoption

• Configure for real workflows: Design the tool around how your teams plan, approve and report, not around the default setup.
• Role-based training: Train project managers, resource managers and executives on the tasks they actually do in the system.
• Visible leadership use: When leaders review portfolio data in the tool, teams keep it current.
• Retire parallel systems: Set a date to stop accepting updates in old spreadsheets and trackers.
• Plan for after go-live: Budget for support and refinement in the months after launch, when most adoption problems appear.

While there are many pitfalls in DIY PPM implementation, these four are the most common and the most dangerous, because each one sets off bigger problems.

They are particularly critical not only because they can cause significant damage but also because they can be rapidly addressed through effective PPM implementation. Unfortunately, DIY PPM approaches often miss this opportunity and end up in the predicament outlined at the beginning of this article.

Moreover, these challenges are often interconnected, creating a domino effect. Fixing one issue might trigger another, leaving you in constant firefighting mode. Effectively addressing these problems and avoiding potential pitfalls requires a comprehensive implementation approach.

Unless you enjoy constantly anticipating and solving new challenges, partnering with an expert PPM implementation service is the best approach to avoid these pitfalls.

The only way to avoid the pitfalls in PPM is to prevent them altogether

Setting sail with only knowledge of the ship (your business and its requirements) and the destination (your goals) is a recipe for trouble, and it's where many DIY PPM implementations go wrong.

A successful voyage also takes knowledge of the water. An experienced implementation partner has seen the rough patches many times and builds a PPM foundation designed to handle them. If you're still deciding how to approach your implementation, a readiness assessment shows where your processes, data and ownership stand before you commit time and budget.
