In the realm of project management, aiming for success is a rule even though achieving that goal can be a challenge. The practice and meticulous study of project management discipline have revealed patterns of errors and counterproductive practices that often lead to project failure. These failures, which I refer to in the "Manual del Enfoque Evolutivo" as the 7 deadly sins of projects, are inspired by historical teachings and are adapted in this Manual to reflect pragmatic obstacles in the modern context of project management.


 

Taking an insight inspired by Edward Merrow's analyses in his book Industrial Megaprojects - Industrial Megaprojects: Concepts, Strategies, and Practices for Success, these "sins" turn into learning opportunities for us project managers. Each one represents a critical area where the conscious and strategic application of the Evolutionary Approach can prevent failures and promote success.


 

Knowledge and prevention of these "sins" are crucial to avoiding common errors and strengthening the chances of success for any project. In this article, I would like to share each "sin," examining its influence on projects and discussing corrective approaches aligned with the Evolutionary Approach. This reflection and adaptation are vital for the modern project management professional, committed to leading teams and projects towards the success of their goals.


 

Thus, the intention is not only to identify the dangers but also to focus on how the use of correct approaches can provide the tools to transform these challenges into competitive advantages. We establish a tone of continuous learning and improvement, framing the "sins" as starting points for growth and excellence in project management.




1. Lack of Clear Objectives

Clarity in objectives is the beacon that guides project management through uncertain seas, what we call VUCA (Volatility, Uncertainty, Complexity, and Ambiguity). The absence of well-defined goals can condemn a project to deviate from its course, leading to confusion and the waste of precious resources. This "sin" undermines the core of any initiative, turning the path to achievement into a maze of doubts.


 

To combat this deficiency, the Evolutionary Approach prescribes not only Specific, Measurable, Achievable, Relevant, and Time-bound (SMART) objectives but also an iterative and collaborative process for defining and refining these objectives:


 

Strategies for Defining Concrete Objectives:


Deep Understanding

The project's vision and mission should echo the organization's values and strategies. The Evolutionary Approach advocates for a comprehensive understanding that serves as a foundation for objectives that reflect the project's essence and aspirations.



Active Collaboration

Encouraging active participation from all stakeholders in formulating objectives ensures their relevance and feasibility. The Evolutionary Approach is notable for creating collaborative environments where diverse perspectives enrich goal definition.



Effective Communication

Transparency and clarity in communicating objectives are crucial to fostering shared commitment. The Evolutionary Approach promotes the creation of a common language and mutual understanding to unify the team around a common purpose.



Rigorous Monitoring

A system of continuous monitoring and review allows for the recalibration of objectives as the project progresses. In the Evolutionary Approach, periodic review is a standard practice that ensures the relevance and adaptability of objectives in the face of changes.



By applying these strategies through the lens of the Evolutionary Approach, objective setting becomes a dynamic and adaptable process. Teams can move forward with confidence and agility, ensuring that each step taken is aligned with a clearly articulated purpose and consistent with the project's success.




2. Poor Planning

Poor planning often acts as the iceberg capable of sinking a project's ship. As detrimental as the lack of clear objectives, the planning process needs to function as the rudder, steering the project to success. Without a meticulously drawn roadmap, the project is vulnerable to chaos and disorder.



Inadequate planning can compromise the project's integrity from its foundation. More than a set of operational failures, it represents a systemic failure with the potential to derail efficient management of time, resources, and budget, resulting in chronic delays, excessive costs, and, in the worst-case scenario, total project collapse. To combat this fragility, several focused practices are recommended:


 

Strategies for Rigorous Planning:


Detailed Task Definition

Ensure that each activity is clearly defined, including its purpose and the necessary resources.



Realistic Schedule

Develop a schedule that considers the project's realities and contingencies, establishing flexible and realistic milestones.



Strategic Allocation of Responsibilities

Clarify responsibilities and allocate resources efficiently to ensure smooth operability.



Precise Budgeting

Make cost estimates that provide a reliable framework for project financial tracking.



Adoption of Advanced Methodologies

Implement planning methodologies, such as Front-end Loading (FEL), widely advocated by professionals like André Choma , that encourage a structured and in-depth approach from the initial phases.



Risk Anticipation

Identify potential risks in the early stages and develop robust contingency plans to respond promptly to unforeseen events.



Continuous Communication with Stakeholders

Maintain clear and regular communication with all stakeholders to align planning with expectations and proactively react to changes.



Under the Evolutionary Approach, poor planning is seen as an opportunity to strengthen the project's vision and strategy. It's not just about establishing an initial plan but about cultivating the ability to adapt and evolve that plan as new insights and challenges emerge. This is the essence of effective planning: a commitment to continuous adaptation and precision that constitutes the heart of all successful initiatives.



3. Poor Communication

Communication is the lifeblood of project management; without it, vitality and clarity are lost. Representing the third deadly sin, the Evolutionary Approach aims to redeem this critical aspect. Data indicates that project managers spend about 90% of their time on communication, underscoring the critical need for impeccable communication.



Ineffective communication can be the trigger for a cascade of problems: misunderstandings, misinformation, and conflicts that not only hinder operational execution but also disrupt order, trust, and team cohesion. Thus, adopting a structured and proactive communication strategy is not a luxury but an urgent necessity.



Strategies to Strengthen Communication:


Comprehensive Communication Plan

Developing a plan that clearly establishes channels, frequency, and communication protocols ensures that all stakeholders are informed and engaged.



Agile Communication Practices

Applying agile methods that promote frequent interactions and constant feedback ensures alignment and enables concerns and challenges to be promptly addressed.
 


Collaboration Technologies

Using collaborative tools like Teams, Planner, Trello, Artia, and many others that support synchronous and asynchronous communication, especially important for distributed teams, enables real-time information sharing and maintains effective communication.



Culture of Transparent Communication

Fostering a culture where transparency prevails and each team member feels valued and heard ensures that ideas and concerns are expressed and considered with respect.



Communication deficiency reflects organizational culture, and addressing it requires promoting a transformation towards openness and active collaboration. It is a call to create an environment where communication is not just technical but also an integrated part of everyday work practices.



Under the Evolutionary Approach, overcoming poor communication becomes an ongoing effort to ensure clarity, cohesion, and collaboration at every stage of the project. The 90% figure not only highlights a problem; it underscores an opportunity for growth and efficiency in project management. Through these strategies, we commit to transforming communication into a powerful tool that enhances project achievement and synergy among teams.



4. Ignoring Risks and Issues

Recognizing and managing risks is not optional; it is the essence of conscientious and prudent project management. Ignoring risks is a deadly sin that can lead to project failure, which is why the Evolutionary Approach advocates for the integration of risk management as a continuous and fundamental practice.



Proactive Strategies for Risk Management:


Constant Identification and Assessment of Risks

Early recognition and continuous assessment of risks are crucial. The Evolutionary Approach emphasizes iterative review of risks throughout the project, enabling agile responses to emerging uncertainties.
 


Development of Flexible Mitigation Strategies

It is essential to plan mitigation and contingency for each identified risk. These strategies should be flexible enough to adapt to unexpected changes, strengthening the project's responsiveness.
 


Culture of Transparency in Risks

Open communication about risks should be encouraged, allowing each team member to feel empowered to point out potential issues without fear of retaliation. The Evolutionary Approach promotes an environment where risk prevention is a collective responsibility.



Rigorous Monitoring and Review

Implementing monitoring systems that allow for continuous updating of risk information, using analytical tools and feedback to adjust mitigation strategies, is vital.



Application of Structured Risk Management Methodologies

Adopting a systematic and methodological approach ensures that risk management is comprehensive and covers all possible aspects of the project, integrating best practices and lessons learned from previous experiences.



This deadly sin underscores the importance of an organizational culture where risk management is recognized as an essential component of project leadership. The philosophy of the Evolutionary Approach considers that risks should not be feared but managed wisely, turning them into elements that add value when properly handled. It is this strategic vision and diligence in risk management that reinforces a project's resilience and ensures its path to success.



5. Lack of Leadership and Commitment

Leadership transcends mere management; it is the energy that drives and synchronizes the various facets of a project. Representing the fifth deadly sin, its absence can leave the project adrift, without a captain to steer it. From the perspective of the Evolutionary Approach, we understand that effective leadership is the vital connective tissue that inspires, motivates, and guides.



The lack of decisive leadership and active commitment can lead to a chasm of indecision and inertia. A transformative leader not only sets goals but also cultivates passion, provides guidance, and turns conflicts into opportunities for growth.



Strategies to Strengthen Leadership and Commitment:


Demonstration of Consistent Leadership

The manifestation of effective leadership should be evident from the outset, setting a course of action and promoting a culture of transparency and collaboration.



Promotion of Communication and Participation in Decision-Making

Exceptional leaders practice proactive and clear communication, encourage collective decision-making, and ensure that the team moves forward united in all stages of the project.



Encouragement of Total Commitment

It is crucial to foster a sense of ownership and responsibility among the team and stakeholders, ensuring that each individual is fully engaged with the project's vision.



Recognition of Successes

Celebrating achievements and valuing individual efforts boosts morale and encourages continuous and dedicated performance.



Leadership and commitment go beyond the structural pillars of project management; they are the essence of its successful execution. The Evolutionary Approach recognizes that effective leadership and genuine commitment are crucial not only for achieving project objectives but also for fostering a rich and productive work environment. Faced with the inherent complexity of project management, dynamic leadership and absolute commitment are the foundations for remarkable results.



6. Poorly Managed Changes
 

Changes, constant and ubiquitous, represent the sixth deadly sin when poorly handled. The dynamic nature of projects demands an agile and considered response to alterations. Ineffective change management can trigger a host of complications, from deviations in the plan to unmet commitments and discouraging outcomes.



Changes can occur for various reasons: requirement updates, regulatory alterations, market fluctuations, or technological advancements. When not managed wisely, they threaten the stability and viability of the project. The Evolutionary Approach views change as inherent to the project management process and advocates for a robust system for its handling:



Effective Strategies for Change Management:


Detailed Recording of Changes

Each change must be meticulously documented, detailing all its aspects, ensuring clear understanding and a reference for tracking.



Deep Impact Assessment

Before proceeding, it is crucial to assess how each change will affect the project as a whole, considering the effects on schedule, costs, quality, and scope.



Rigorous Approval Process

Implementing a review and approval protocol that confronts each change with the project's strategic objectives, ensuring its alignment with the overall vision.



Implementation Management and Supervision

Approved changes must be carefully integrated, and their impact closely monitored, allowing agile adjustments as necessary.



The Evolutionary Approach proposes an approach to change management that is both reactive and proactive, anticipating and valuing changes as opportunities for improvement and optimization. Far from being viewed as sources of disruption, changes are considered catalysts for innovation and growth.



The ability to absorb and adapt to changes effectively provides projects with the resilience and flexibility necessary to thrive in an ever-changing business environment. Well-planned and anticipatory change management ensures that the project not only stays on course but also enriches and strengthens with each new challenge and opportunity that arises.



7. Failure to Learn from Mistakes

Recognizing and learning from mistakes is fundamental to any growth process, especially in project management, where this practice takes on a critical character. The seventh and final deadly sin, the inability to learn from mistakes, can be the most subtle and damaging of all, as it blocks continuous development and innovation. The Evolutionary Approach highlights the importance of iterative learning and progressive improvement of best practices.



Confirmation bias represents a trap that all projects must avoid. It obscures objective vision and limits the team's ability to adapt and evolve. However, the Evolutionary Approach offers an antidote to this bias, encouraging teams to cultivate a mindset of continuous improvement.



Strategies to Promote Continuous Learning:


Promotion of Transparency and Self-Criticism

Create an environment where mistakes are seen as learning opportunities, not as failures, encouraging analysis and open discussion of decisions and their outcomes.



Periodic Reviews with Diverse Perspectives

Integrate a variety of perspectives, including an interdisciplinary team in project reviews, to minimize conformity and stimulate critical thinking.



Recording and Analysis of Lessons

Learned Maintain a systematic record of errors and decisions, analyzing them to extract patterns and lessons that inform future improvements.



Education About Cognitive Biases

Raise awareness among the team about common cognitive biases and provide tools to mitigate their impact on decision-making. Implementation of Data-Driven Improvements Prioritize objective analysis and empirical evidence over intuitions or past experiences when implementing changes, ensuring decisions are data-driven.



The Evolutionary Approach transforms project management into a virtuous cycle of experimentation, reflection, and continuous improvement. Every setback is seen as a potential breakthrough, and every mistake becomes a step toward future success. This approach not only optimizes the effectiveness of ongoing projects but also prepares teams to face future challenges, fostering a resilient and adaptable culture.
 


Conclusion: The Virtue of Continuous Learning and Strategic Reflection

As we navigate the intricate challenges of project management, the "Seven Deadly Sins" emerge not only as obstacles to be avoided but, more deeply, as fundamental lessons for our growth and success. This article explored each sin with the intention of illuminating the paths by which we can turn potential failures into foundations for innovation, efficiency, and project fulfillment.



At the heart of this discussion lies the idea that improvement in project management transcends mere error correction; it involves a paradigm shift in how we perceive and respond to adversity. The adoption of the Evolutionary Approach by me and my team, inspired by the reflections of Edward Merrow and enriched by practice and observation, proposes a virtuous cycle of learning, adaptation, and continuous improvement.



The invitation to reflect and engage in open dialogue on these issues is essential to foster a community of practice that values transparency, resilience, and continuous innovation. As project managers, we must share our experiences, successes, and learnings. Together, we can build a richer understanding and more robust practices in the art of project management.


Questions:
1. What strategies have you implemented to overcome the "Seven Deadly Sins" in managing your projects?
2. Was there a time when one of these sins nearly compromised a project? How did you and your team overcome it?
3. How does your company's organizational culture influence management and learning from these common errors?
4. In what ways has technology been an ally in overcoming these challenges?

As we delve into the depths of these sins and emerge with corrective strategies, each project becomes an opportunity not only to achieve specific objectives but also to enrich our competence and collective wisdom. This path to excellence in project management is always under construction; each new project is a chance to apply, learn, and innovate.

These are all so pertinent, Wellinghton, and "deadly" is a good description for them.

I find the one most neophyte project managers often fail miserably at is #6 Poorly Managed Changes. This item refers to changes in a project such as scope change, or the impact of changing resources and the need to track all of this meticulously and action it appropriately.

I would put an additional spin on change management. That is, as it related to Organizational Change Management. Maybe it falls under #3 Poor Communichation, since that is one of the items a professional change manager deals with or perhaps under #1 Lack of Clear Objectives, Effective Communication. I believe it is the responsibility of the project manager to ensure the team includes a change manager and that there is an organizational change management plan developed as part of the project.

Maybe this could be an 8th deadly sin: "Failure to plan for the people side of change" since, after all, projects are all about implementing change into an organization.

Thanks for this detailed information Wellinghton!

Actually, each of the so-called "Sins" are due to the lack of knowledge and understanding of the human side of life, as well as within programs/projects.

I learned, starting in 1985, what you state is true within design and construction orgs at the very least 60% of the time, and probably more. This results in a rush to "Conflict Mgt." rather than addressing the root-causes.

In 1995 at the conclusion of a 2 year study of engineering education by the ASCE, the very deficiencies noted were identified as required going forward. And yet, no change in that direction happened.

In 2024 and beyond, in addition to this systemic void, we now have to address
multigenerational and multicultural workplaces.

Professor William, thank you for your feedback!



It is truly disheartening to realize that these "sins" were already identified back in 1995, and yet, despite countless studies and publications, we continue to repeat the same mistakes. This reinforces Professor Bent Flyvbjerg’s theory on the Syndrome of the Eternal Beginner—a phenomenon that transcends generations and keeps us trapped in the same cycles of failure, regardless of technical and methodological advancements.



I wasn’t familiar with Dr. Deming’s work, but I’m very curious to learn more about his theories, especially PDSA. Thank you for the recommendation! I’m sure there’s a lot to gain from his approach.

Risk number 4: "Ignoring risks and issues" is an important aspect that is frequently forgotten when managing projects.

*In various Control Access installations, ignoring risks from the beginning of the project has resulted in undesired results that are perceived by the final user and give a bad image of the product.
Ignoring important issues and risks can be fatal and even lead to a project cancellation.

*Implementing a lesson learned database is useful to register these experiences and not repeat the same error in the future.

*Even though each project has its particular risks, according to the nature of the project, the area of knowledge, environmental conditions, political circumstances at the moment, etc, we can state certain processes to guarantee adequate risk management:

*Risk identification:
-Using techniques such as Brainstorming, Delphi Technique, Root Cause Analysis, and interviewing experts.
-Establishment of a risk register -SWOT analysis
-Cause and effect diagrams

* Qualitative risk analysis:
-Subjective evaluation of risk.
-Risk probability and impact assessment.
-Risk categorization

*Quantitative risk analysis:
-Numerically analyzing the effect of identified risk on project objectives
-EMV Decision Tree
-Data gathering and analysis. Modeling techniques.

*Plan risk responses

*Control risks

I agree 100% with all the deadly sins of PM. Lack of clarity is appropriately ranked in the #1 spot, as this sin undoubtedly leads to and / or contributes to the other 6. I cannot stress enough the need for clarity throughout every aspect of PM. Clarity of objectives, clarity of requirements, clarity of roles & responsibilities, etc. If nothing else, driving clarity can literally cover a multitude of sins.

Excellent insights, Wellinghton Pereira Barboza
Your framing of the “seven deadly sins” in project management is both compelling and practical.
I particularly appreciated the emphasis on leadership and communication — often overlooked, yet so central to project success.
If I may offer a constructive note: it could be enriching to also consider how emergent objectives play a role in complex environments, and how lessons learned can be more effectively integrated into future project cycles.
Thank you for sparking such a relevant and timely discussion!
