As mentioned in the previous sections, the integration of sustainability generates a new project management paradigm, leading to a shift in the mindsets of project managers towards sustainable development concerns. Thus, this paradigm depends on how project managers are committed to this challenge and how they may even assume the role of changemakers.
In literature project managers are incentivate to integrate sustainability into their projects. In general, most of the managers surveyed reported that they incorporate sustainability into their activities due to their internal motivations as they believe that sustainability is a worthy pursuit. Thus, the results of these studies indicate that intrinsically motivating factors are the main incentives, rather than the other two sets of stimuli, as when the project manager has an intrinsic orientation towards sustainability, task-driven and pragmatic motivations have little significance. The research reinforces the importance of individual stimuli, as it concluded that these results do not depend on project typology, age, gender, or the type of industry in which the project is developed.
6. Discussion and Conceptual Contribution
The challenges of the 21st century include combating the severe climate changes accelerated by human action in the Earth’s ecosystem and adapting humanity to energy and digital transitions, leaving no one behind. For these reasons, sustainability is the keyword nowadays.
From the late 1960s, the ecological impact of human actions has been questioned, and nowadays its relevance to the fragility of the planet’s sustainability is evident. Nevertheless, given the importance of this ecological aspect, several authors insisted that the sustainability concept should go wider and be made more comprehensive, including social and economic dimensions along with environmental factors. Therefore, one cannot act in relation to one aspect of this triple bottom line vector without influencing the others.
To respond to the current challenges, all the disciplines, all types of services, schools and academies, and rural and mechanical industries should acquire this triple global vision and adopt concrete measures, sometimes individually and sometimes as a group. The awareness of everybody’s involvement is crucial to reach the desired end, and this awareness leads to changes in working processes and relational methods.
In the life cycle of product development and production, product managers have already been taking care of certain dimensions, including the ecological concerns, whether by limiting the use of certain types of raw materials, such as plastic, avoiding disposable materials, or offering alternatives for product destinations either by recycling the product or prepare it to act as a secondary raw material, ready for a new life. These actions widely adopted are not purely empirical but supported by the literature, for instance, the sustainability innovation cube of Hansen, Grosse-Dunker, and Reichwald [
44] that adopts the triple bottom vectors approach to create a framework to evaluate sustainability-oriented innovations directed at encouraging product managers to act along the life cycle of a product, through manufacture, usage, and the end of the product’s life.
This project intends to help promote the integration of environmental sustainability actions in project management daily practices. The results obtained so far were compiled as a set of practices oriented towards environmental sustainability, designated as the Curated Treasury. This list will allow project managers to make more conscious decisions about the impact of their projects with a similar project life cycle (as presented previously in Table 1). In addition, these practices promote the motivation of project managers to develop their projects in a more sustainable approach.

The results are much more ambitious and not limited to an extensive list of good practices. This perspective leads project managers to the most suitable decision making considering the context of each project. Thus, one of the first steps to integrate sustainability into PM should be the analysis and selection of practices throughout the project life cycle, allowing the meeting of sustainability concerns in a customized and appropriate way to fit each project’s scope, as conceptually presented in Table 2.
Table 2. Conceptual model of Think Twice’s PDLC approach.

The PDLC approach avoids initial enthusiastic ecological intentions that will fade or be forgotten in the management and implementation phases. Adopting sustainable practices supporting the project’s life cycle contributes to the integration of sustainability in PM, not only comprehensively but systematically.
With the Think Twice results, the project manager is challenged to commit all stakeholders to act in conformity to ecological sustainability along the project development life cycle. What about the other two triple bottom dimensions, though?
With this question in mind and with the project results as a starting point, the authors identify an opportunity to go beyond the ecological analysis achieved by the TT project. By applying the same methodology as before, the scope of the analysis was expanded towards the triple bottom line sustainability approach to complement the project manager’s good practices.
The next section describes the conceptual model that led to a more extensive list of good practices for project managers where the other two sustainability dimensions were included. The three sustainability dimensions approach was called the project management triple sustainability cube (of good practices).
Conceptual Model to Assess Sustainability Dimensions in PM
The classification of sustainable practices catalogued by the project Think Twice could be an important contribution to stimulate the sensitivity and awareness of project managers, convincing them to adopt relevant attitudes towards sustainable goals in project development. However, it is limited to only one sustainability dimension, the ecological dimension.
To extend the range of the list of the TT’s Curated Treasury of good practices towards the triple bottom line sustainability vision, the list was revisited and reorganized, and a conceptual model was built to reach this vision.
The first approach to the findings led to the emergence of a second dimension combining the ecological practices into families of related actions, named the variable dimension. Those variables are V01, Processes Green Indicators; V02, People and Systems; and V03, Go/No Go Digital or Innovation.
The group V01 corresponds to the ecological practices that are general to an organization and not specific to a given project. Instead, they are transversal actions or decisions that concern, not a specific project manager, but the organization that leads the project development.
Inside this category are actions such as those regarding workplace conditions or choices about team mobility and accommodation. An example of this kind of decision might be: How can the project manager choose the most environmentally friendly hotel for his international team to meet at?
Such V01 good practices should be seized by specific indicators and that’s because they were labelled as PGI (Process Green Indicator)—Process Green Indicators. These indicators should be objective and measurable to support the PM’s decision when adopting V01 practices in answering questions like: How can I compare different hotels concerning their ecological consciousness?
At this point, a new study area is identified for further research. Taking this example, one can suggest the creation of new accommodation green metrics, such as the ones used at home for appliance energy indicators A++, A+ … Hotels (or even transport methods, mutatis mutandis), then, could be labelled as (say) 4-star A++.
The group V02 corresponds to practices that refer to the impact of the actions of the team in the development of a certain project and how they affect the processes and systems that are used.
These can or cannot be generalized to the organization and are specific to the decision of the project manager along the PDLC. As an example of this group of practices, one can have, for example: Should I print all the intermediate reports or leave them in a repository and print only the final one?
Here, also, objectivity is imperative to decide among different options. Even though some of these decisions are common sense, they should be supported with the most objective indicators possible.
Finally, V03 concerns the specific project and includes all the practices that bias team decisions to use digital alternatives instead of physical solutions. This vector was named the Go/NoGo Digital dimension. This dimension may also be called digital innovation and is intended to guide project managers in choosing the border limits between the physical and the digital world.
These new classifications allow the development of a two-dimensional classification along the life cycle. Each one of the actions under the scope of the new variables V01, V02, and V03, can be equally adopted along the project’s life cycle (Table 3).

Note that at this point the four PDLC stages adopted in the Think Twice project were reduced to three, as the Dissemination and Evaluation phases were grouped.
So far, the exhaustive list of ecological good practices was reorganized along with a bidimensional conceptual model based on the project life cycle and a new family of variables described above.
The next step towards a complete list of good practices based on the holistic triple bottom line vectors of sustainability adds all three vectors to the developed conceptual model: the ecological sustainability vector (EcoS), the social sustainability vector (SocS), and the economic sustainability vector (EncS) (Table 4).

The introduction of the new vectors of sustainability dimensions requires the incorporation of an extended list of project management best practices concerning the social and the economic aspects of project development life cycle stages and variable dimensions. Subjects such as child labour, fair trade, or extremely low wages should be addressed at this time.
The complete conceptual model based on the three dimensions is now a 3D model in all the dimensions numbered above. This will allow the new Curated Treasury to be redistributed according to its target dimensions (Figure 1).
Figure 1. Correlation among the model dimensions, PDLC, variables, and sustainability.
To better picture the model and easily find the axis of action, the three conceptual dimensions are depicted in a 3D view that represents the Project Management Triple Sustainability Cube (Figure 2).
Figure 2. The project management triple sustainability cube of good practices.
The Project Management Triple Sustainability Cube model is a conceptual model that shows the transversality of three interrelated dimensions of sustainable project development along the project life cycle. It identifies 3 × 9 individual areas of sustainability procedures that may be adopted by project managers in each project development.
By adopting this methodology and achieving a group of 27 practices, each project manager could objectively identify the adoption of each group of best practices along each axis and at each stage of project implementation. By highlighting each of the 27 sustainability areas in which actions were taken in a certain project, project managers can improve and forecast improvement areas for current and subsequent projects.
The Project Management Triple Sustainability Cube outlines guidelines for adopting comprehensive practices in relation to the triple bottom line sustainability vectors (environmental, social, economic) concerning people, processes, and innovative solutions (go/no digital) along the project development life cycle to support the decision making of sustainability-concerned project managers.
