Integrating Mindfulness in Project and Program Management

Revision as of 20:11, 26 September 2016

Mindfulness is a state of consciousness in which attention is focused on present-moment phenomena occurring both externally and internally.^[1] This present-moment phenomena can also include embarking in creative imagination about the future, problem solving in the present or analysis of the past - as well as a discerning capacity of observing the present situation and context without falling into habitual tendencies or routines.^[2] This targets a number of challenges for Project and Program managers in where, due to time pressure, uncertainty and personal cognitive biases, sub-optimal decisions are often made highly impacting the projects outcomes.

This article intends to build upon the growing number of theories and evidence of the benefits of mindfulness, from two perspectives: individual and collective. It will draw from the latest research on the topic and link it to the existing framework for Mindfulness in High Reliability Organizations (HRO), developed by professors Karl E. Weick and Kathleen M. Sutcliffe. Finally, the article will finish by suggesting potential integration of these approaches that professionals can undertake in order to improve their Project and Program Management within their organizations.

Context

Historical definition of Mindfulness

Figure 1: Time Magazine - February 2014

The earlier account of the meaning of the world mindfulness comes from the Pali-term sati, simply meaning a state of non forgetfulness, bearing in mind a given object of attention. This includes retrospective memory of things in the past; prospective memory, to remember to do things in the future; and present centered recollection in the sense of maintaining attention to the present reality. ^[2]

In several contemplative traditions mindfulness this mental factor is viewed as a pre-requisite to: 1) Develop attention/concentration skills 2) Develop empathy and altruism; and 3) Developing cognitive balance. The latter can be generally understood as the self-awareness of our own internal mental processes, cognitive biases and tendencies, and the degree of freedom to which an individual can refrain from acting on them.^[3]

Mindfulness in the West

Even though there are earlier accounts of Mindfulness in the West, the recent popularity of the concept of Mindfulness in the West is generally attributed to Jon Kabbat-Zinn and his work on Mindfulness Based Stress Reduction (MBSR) programme. The adoption of mindfulness related practices/training has been widespread, ranging from training and development programs of major corporations from Google to General Mills, to programs in prisons to prevent work burnout of juvenile guards.

Universities, too, have taken up the call. For example, the director of mindfulness education at UCLA’s Mindful Awareness Research Center leads on average 200 people every week in a silent Mindfulness Awareness meditation class held at the Hammer Museum’s Billy Wilder Theater ^[4]

Recent research

Figure 1: Mindfulness Research Publications: 1980-2013

The past 30 years have seen exponential growth in research of Mindfulness. Much research concerned with the development of individual-level mindfulness maintains that mindfulness can be developed through meditation. The research takes its cue from Jon Kabat-Zinn's MBSR programme but also a variety of other Mindfulness Based Interventions (MBIs) i.e.: mindfulness-based cognitive therapy ^[5]

Building on the view that mindfulness is a byproduct of meditation experimental research has shown that state mindfulness can be activated through brief meditation-related instructions and exercises ^{[6] [7]}

The growth in mindfulness research literature from 1980-2013 is shown in the graph at the right-handside.

Individual Mindfulness

Benefits of Individual Mindfulness

Different research on mindfulness has proved its varied impacts on health, performance and emotional regulation. Some of the key findings presented include:

• enhanced psychological and physical well-being ^[9]
• slow aging ^[10]
• improve standardised test performance ^[11]
• Research has demosntrated that meditative training programs reduce work-related stress ^[12]
• Hülsheger et al. found through a field experiment with working professionals that mindfulness reduced emotional exhaustion and increased job satisfaction.^[13]

Even more relevant to our case in point, organisational research indicates that individual mindfulness is positively related to employee outcomes such as:

• Work engagement^[14] and
• Job performance:
  • One a study of nuclear power plant operations found found that trait mindfulness was positively related to job performance for operators who held jobs high in task complexity ^[15]
  • Another study found a positive relationship between workplace mindfulness and job performance among those working in a dynamic performance environment (the restaurant service industry) that remained significant when controlling for three dimensions of work engagement. ^[16]
  • Reb et al. found positive relationships between work-related mindfulness and task performance and organizational citizenship behavior, respectively, within their survey of working adults. ^[17]
  • Employees high in trait mindfulness responded more strongly to ethical leadership in terms of the effort and helping behaviors they put forth. This suggests that, in the presence of an ethical leader, individuals high in trait mindfulness are more likely to perceive and embrace the values and behaviors they perceive in ethical leaders and to perform accordingly.^[18]
  • Mirroring the last finding, another study found that the trait mindfulness of supervisors is positively related to the well-being and performance of their employees. ^[17]

These findings suggest that the mindfulness of one person in an organization can influence the well-being and performance of others and also that individual mindfulness practice can have an impact accross all levels of organization, ranging from strategic and tactical to operational. Suggesting the mindfulness contributes to an organisation's bottom line.

Collective Mindfulness

Collective mindfulness was originally developed to explain how high-reliability organizations (HROs) avoid catastrophe and perform in a nearly error-free manner under trying conditions. Over time, the focus has expanded to include "organizations that pay close attention to what is going on around them, refusing to function on ‘auto-pilot’”. Collective mindfulness is a means of engaging in the everyday social processes of organizing that sustains attention on detailed comprehension of one’s context and on factors that interfere with such comprehension ^{[19] [20]}

Some of the most common definitions of Collective Mindfulness highly influenced by Weick et al. work along the years are the following:

Benefits of Collective Mindfulness

Investigation on the employee and organisational consequences of collective mindfulness - defined as the collective capability to discern discriminatory detail about emerging issues and to act swiftly in response to these details^[20] - and, in doing so, have found an array of benefits. For employees,

• mindful organising is associated with lower turnover rates.^[21]

For organisations, collective mindfulness is positively related to salutary organisational outcomes including:

• more effective resource allocation ^[22];
• greater innovation ^[23];
• improved quality, safety and reliability ^{[24] [25]}

Interestingly, these effects are most commonly observed in particularly trying contexts charactered by complexity, dynamism, and error intolerance. This suggests that some of these benefits can be achieved even in the toughest project and programs situations.

Why is it important? The Impact of Human Behaviour on Project and Program Management

Project success rates have improved, and much of the credit can be given to the knowledge, practices, and standards that have contributed to the professionalization of the field. Unfortunately, too many failures still occur and many of them can be traced to management and decision-making practices.

Independent of the actual complexity of a project is the way we perceive and manage this complexity. Arguably, regardless of the project's "real” complexity, what count are our perception and reaction to it. ^[26]

We are incredibly adaptable at learning although our capacity to make decisions is limited by at least three main factors:

• Our access to information will never be perfect and completely and accurately represent the full current state;
• We have cognitive limitations—for example, regarding the number of factors we can consider in parallel, the amount of information we can take up, or the speed with which we can process it; and
• The time we have to make a decision.

Adding to these cognitive limitations, our subconscious or built-in decision-making models and routines, i.e.: cognitive biases and heuristics, can often be detrimental when trying to come up with optimal solutions/responses when managing complex systems. As McCray et al suggest, "Why are poor decisions (in projects) made? The answer may lie partially in the unrecognized effects of heuristics. Many heuristics are largely or completely unseen, occurring without the individual recognizing their presence or impact. When applied to forecasts of resource requirements for a project, management actions taken during an ongoing project, or even reflections on completed project work, these heuristics often manifest themselves as subtle but powerful biases in decision making."^[27]

A strong advocate of this idea is Nobel lareaute Daniel Kahneman. "Humans are not the rational beings they think themselves to be" argues Kahneman in his book Thinking Fast and Slow, where he unpacks his life-long research on prospect theory which, in a nutshell, addresses the idea that: the experimental faults in Daniel Bernoulli's traditional utility theory and challenging that economic rationality of Utilitarian theory do not reflect people's actual choices under risk, by not taking into account their cognitive biases.

Below are some of the key findings on these topics, illustrated with examples, and how they directly affect decision making at large and project/program management in particular:

Framing

Framing is the context in which choices are presented. People tend to avoid risk when a positive frame is presented but seek risks when a negative frame is presented.

Example: Participants were asked to choose between two treatments for 600 people affected by a deadly disease. Treatment A was predicted to result in 400 deaths, whereas treatment B had a 33% chance that no one would die but a 66% chance that everyone would die. This choice was then presented to participants either with positive framing, i.e. how many people would live, or with negative framing, i.e. how many people would die.

Treatment A was chosen by 72% of participants when it was presented with positive framing ("saves 200 lives") dropping to only 22% when the same choice was presented with negative framing ("400 people will die").

Optimism bias and the Planning Fallacy

Kahneman explains a "pervasive optimistic bias", which "may well be the most significant of the cognitive biases". Associative memory leads us to respond fairly automatically to new stimulus by framing them on the network of experiences that we have been through before. The danger, however, is when the situation is in fact new and treating it merely like a previous situation might lead us to disregard important factors, details or new information that would require greater effort - or mindfulness - to apprehend and act upon. This leads to people having overconfidence in judgements that are not necessarily true.^[28]

When we find ourselves in front of a question that we can't answer, our internal instinctive process is to answer a similar easier question we had in the past and use this answer instead. People are often unaware of this substitution process and that it will use the right answer to the wrong question.

To explain overconfidence, Kahneman introduces the concept he labels What You See Is All There Is (WYSIATI). This theory states that when the mind makes decisions, it deals primarily with Known Knowns, phenomena it has already observed. It rarely considers Known Unknowns, phenomena that it knows to be relevant but about which it has no information. Finally it appears oblivious to the possibility of Unknown Unknowns, unknown phenomena of unknown relevance.

In 2003, Lovallo and Kahneman proposed an expanded definition of the Planning Fallacy as the tendency to overestimate benefits and underestimate the time, costs, and risks of future actions, impelling people to take on risky projects. These were some of the empirical studies developed to support this:

• In a 1994 study, 37 psychology students were asked to estimate how long it would take to finish their senior theses. The average estimate was 33.9 days. They also estimated how long it would take "if everything went as well as it possibly could" (averaging 27.4 days) and "if everything went as poorly as it possibly could" (averaging 48.6 days). The average actual completion time was 55.5 days, with only about 30% of the students completing their thesis in the amount of time they predicted.
• In 2002, American kitchen remodeling was estimated to cost an average of $18,658, but its actual cost was $38,769 ^[29]

Finally, Kahneman suggests that humans fail to take into account complexity and that their understanding of the world consists of a small and necessarily un-representative set of observations. Furthermore, the mind generally does not account for the role of chance and therefore falsely assumes that a future event will mirror a past event.

One of the most emblematic real world examples:

The Sydney Opera House was expected to be completed in 1963. A scaled-down version opened in 1973, a decade later. The original cost was estimated at $7 million, but its delayed completion led to a cost of $102 million.

Sunk Cost or Escalation of Commitment

Escalation of commitment refers to a pattern of behavior in which an individual or group will continue to rationalize their decisions, actions, and investments when faced with increasingly negative outcomes rather than alter their course. The related sunk cost fallacy has been used by economists and behavioral scientists to describe the phenomenon where people justify increased investment of money, time, lives, etc. in a decision, based on the cumulative prior investment ("sunk costs"), despite new evidence suggesting that the cost, beginning immediately, of continuing the decision outweighs the expected benefit.

Two famous cases include:

• The Big Dig in Boston
• Sony's continued participation in electronics after $8.5 billion in losses over 10 years

These and other key cases are reviewed and analysed; and the issue of Escalation of commitment is addressed in the two following papers:

- Stray, Viktoria Gulliksen; Moe, Nils Brede; Dybå, Tore (2012). "Escalation of Commitment: A Longitudinal Case Study of Daily Meetings"

- Woods, Jeremy A.; Dalziel, Thomas; Barton, Sidney L. (2012). "Escalation of commitment in private family businesses: The influence of outside board members"

Applications

Individual Mindfulness

It is the author's perspective that, due to the highly contextual nature of Mindfulness practices, it does not make sense to present the meditations here as a one size fits all. Furthermore, there is no substitute for a qualified teacher/guide to support you on an individual practices or to orient which kind of practices are most suitable towards your organization. Instead, please consider the following programs and also refer to the annotated bibliography at the end for good quality references of meaningful practices.

Search inside Yourself: "Born at Google from one Engineer’s dream to change the world, Search Inside Yourself is now a globally-recognized program & network. Bridging age-old practices of mind training with modern neuroscience and technology, we help people in organizations bring out the best in themselves, from the inside out."

Cultivating Emotional Balance (for which the author is a certified teacher): "The Cultivating Emotional Balance research project arose from a dialogue between biobehavioral scientists studying emotion and the Dalai Lama and Buddhist monks and scholars. This meeting, which took place in March 2000, in Dharamsala, India, was one in a series sponsored by the Mind and Life Institute to foster an interchange between the Buddhist tradition and Western science."

Collective Mindfulness: Lessons from High Resilience Organizations (HRO)

The findings of collective mindfulness within HROs have best been summarized by Weick and Sutcliffe, who have developed five principles that harness the key characteristics of collective mindfulness within an organization. These principles are meant as general guidelines on how to implement collective mindfulness within an organization; and their application range upward from a strategic and tactical level of an organization as well as downwards to operational teams, crews and team leaders.

As a complement to these five principles, Weick et al describe the process of reworking your labels and categories as consisting of three main steps^[30]:

1. Re-examine the discarded information;
2. Monitor how categories affect expectations;
3. Remove out-dated distinctions

Firstly, to rework one’s categories mindfully means to evaluate how much information is discarded with a categorization of an instance with similar characteristics. Generally speaking, categorization help gaining control in a fast pace world, they help predict what will happen and plan one’s own actions. On the other hand, a category cannot describe all facets of a person and the individual must be aware of the discarded information within each category.

Secondly, one must pay close attention to how categories effect on our expectations, since these two are e.g.: a person categorized as an expert is expected to know the answers within his/her field of expertise. These expectations constantly have to be revised and evaluated. It may be necessary to differentiate the expectations, replace them, supplement them, or discard the whole category.

Third, mindful reworking means a check whether the categories remain plausible. Outdated categorization with implausible distinctions of expectations ensure trouble. The trouble starts when you fail to notice that you only look for whatever confirms your categories and expectations. “Believing is seeing. You see what you expect to see. You see what you have the labels to see. You see what you have the skills to manage.” People who have a critical approach towards their categories by refining them, updating or replacing them notice more and catch unexpected events earlier in their development.

The case for Mindfulness in Project and Program Management

Projects never go according to plan. Far too many cases could be drawn to support this statement. That is why it is fundamental for project managers to be able to navigate in changing environments.

Taking as an example a recent interview with the Bispebjerg hospital Executive VP, he states that: when managing a project with such a long life cycle (10y) there must be a continuous capacity to adapt in face of the opportunities that make themselves present along the way. "What was a the best technology in the beginning of the project might be mediocre by the end of it". Therefore, we should aim to making the best decisions not only as a way to accomplish the initial plans but also to seize the opportunities that manifest along the way. If we firmly grasp onto our habitual ways of viewing and solving problems, refusing to absorb new information and reconstruct our categories, we become blind to new opportunities presented by our context.

The mere awareness of our own limitations, can help us a great deal in understanding where it is that we need to introduce individual or collective mindful approaches in order to not compromise decision making. As J. Oehmen et al suggest: "While we cannot completely dissolve our cognitive limitations, we can discipline our minds by becoming aware of our “irrationalities” and inspiring ourselves to act in a mindful manner. Our behaviour will become more like we thought it was anyway—rational and fact-based." ^[26]

Already mentioned previously, collective mindfulness refers to processes that keep organizations sensitive to their environment, open and curious to new information, and able to effectively contain and manage unexpected events in a prompt and flexible fashion. If this sounds particularly similar to the job description of a Program Manager, it's because it is. Taking the Programme London Olympics 2012 as an example, part of the success of its management was due to a pervasive, high-level management philosophy adopted across the entire programme; inter-dependency management, and robust problem resolution and change control processes; emphasis placed on human resource management and organisational development capability. ^[31] These tenets can be easily related to principles 1, 3 and 5 suggested by the HROs approach.

Apart from all the objective metrics and targets used to project and program efficient delivery; the human aspect, ranging from work satisfaction, social relations and individual well-being are also a key factor that should be accounted for when considering the beneficial impacts of integrating mindfulness in Project Program and Portfolio Management. In short, even though there are positive outcomes in terms of organizationals performance, a key point is that the benefits of fostering an environment with such a mindset will produce benefits for each individual that will never be captured in its entirety.

Of course there also are limitations to this approach, most of which have to do with the complexity of adapting some of the practices and principles to each particular environment. Furthermore, the breadth of this topic makes it difficult for researchers to come with validly and unequivocal findings about the benefits of such practices, and connecting it directly to outcomes. Finally, these practices are not a substitute for competent leadership and management skills and are only to be viewed as a complement in order to increase quality and performance. Nevertheless, a new field of "Behavioural Projects"^[32] is emerging which targets precisely the issues of integrating cognitive and social psychology theories and decision situations in projects, and how can this field of research best be directed.

It remains your call to decide which stance would you like you and organisation to hold on this topic. Would you rather wait for all the data to come in before embracing a Mindful culture in your organization; or given what is already out there are you willing to try it out and see how well your Project and Program Management can improve. How are you going to manage this risk?
