Exhibit 1. Overview Six Thinking Hats
The main reasons for selecting the Six Thinking Hats included the following properties of the technique:
All project staff including external design consultants assigned to the Athena project were trained in the use of the tool. The training was provided by the senior managers who selected the tool and became certified to deliver the employee training. In addition, the training was also rolled out to other areas of the organization.
The Athena project manager encouraged his team to use their new skills for appropriate project-related work, and planned the agendas of all Concept, Preliminary, Code and Critical Design Review meetings to incorporate the new technique. Team members were also encouraged to use the technique on an ad hoc basis in their daily work.
The innovation skills impact study was designed to gather as much useful information about the learning and application of the skills within the context of the Athena project (see West, 1999 for complete details). Assessment tools and processes were developed to be as non-intrusive as possible, to avoid interfering with product development schedules and to permit naturalistic observation of the flow of work. All team members were informed of the purpose of the impact study and were asked permission to be surveyed and interviewed. All responses were compiled in strict confidentiality. Twenty-eight individuals, consisting of the initial core Athena group, were followed for this case study.
The Kirkpatrick (1998) 4-level program evalutaion model was selected for this study based on its ease of use and acceptance in the assessment field. This model was supplemented with Phillips (1997) 'return-on-investment' model to add a financial dimension to the evaluation. The five levels of evaluation used in this study are defined as:
A measure of participant satisfaction and intention to apply the skills.
Level 2 - Learning
A measure of transfer of knowledge or development of skill or change in attitude.
Level 3 - Behavior
A measure of change in on-the-job activity or application of the learning in real situations.
Level 4 - Results
The business impact achieved by program participants as they successfully apply the skills (changes in output, quality, costs, time, customer satisfaction etc.).
Level 5 - Return-on-Investment
Compares the monetary benefits of the program with the program costs.
Based on interviews with senior Athena project management staff, behavioral objectives were set for the impact study. These were based on observed shortcomings of previous design projects and indicated in what areas the team was expected to improve:
Design Review Meetings
Design Documentation
Clearer description of thinking process for pre-meeting distribution.
The assessment tools for this study were custom-designed to generate data to determine if the training objectives were met and to fit with each of Kirkpatrick's and Phillips' five levels of evaluation. Assessment was done prior to training, immediately after training, throughout the development of the product, and finally as product development wound down.
In order to capture the group's impressions of the design review process as it stood prior to the innovation skills program, team members were asked to rate design review meetings they had attended in terms of 20 meeting elements including meeting management issues, interpersonal communication and climate issues, generation and analysis of ideas, and quality of outcome.
Immediately following their training, team members were asked to assess the training and trainers, indicate whether they had retained the content of the training, and give their impression of the value of these skills to their work at MDS SCIEX, as well as a prediction of where and when they might use them.
During the five months following their training, the Athena team was required to use the new approach in their design review meetings. Approximately 50% of design review meetings were observed in terms of structure and adherence to the agenda, use of new terminology, tone and content of comments.
As the design review phase of the study wound down, each team member participated in a 20-minute interview about their attitudes toward and use of the innovation skills since their training. They were asked to rate the Athena design review meetings in the same way they had rated previous meetings prior to their training.
Organizational learning experts suggest that in order to create lasting change within an organization, the change should not be implemented from the top, but rather introduced from the middle or lower levels, in projects where the new approaches are most valuable and relevant to staff (Senge, 1999). The changes should be cultivated carefully, allowing self-reinforcing processes free reign and clearing away potential change barriers. The innovation skills program successes may be due in large part to an attempt to take such an approach to introducing change: supporting one cross-functional group's efforts to improve its own effectiveness and efficiency.
Originally, senior Product Development staff introduced the Six Thinking Hats program to improve perceived shortcomings in the design review process. Of note was that this desire to improve was echoed by the remaining Product Development staff. Measured before the skills training, their average rating of 20 design review meeting elements ranged from ?could use improvement? to ?adequate?. Both management and staff tended to agree on which were the problem elements (e.g., tolerance for all viewpoints, exploration of ideas, building constructively on each others ideas, quality of decisions).
A shared commitment to the Six Thinking Hats program as a potential remedy was also clear by the end of the training days: 76 % of the group felt the techniques would improve their work and 86 % agreed with senior staff that the tools would improve the design review process. Management and staff consensus of both the need to improve and the relevance of the improvement strategy no doubt fueled the success of the innovation skills program at MDS SCIEX.
Organizational learning experts have found that deep and lasting change occurs only with personal growth, and the commitment of all group members to self-generated change as opposed to compliance to top-down demanded change. The Athena project development team began to manifest this by actively using the Six Thinking Hats skills over the five months of intensive design review meetings observed for the impact study. During the first design review meetings, adherence to the Six Thinking Hats agendas was strictly enforced by the project manager, but soon most participants were also using the terminology to preface their contributions and to regulate each other's comments, often with good-natured humour. They would draw attention to violations of the agenda colour in use (Hey, you're red hatting my green hat!), ask to revisit an agenda colour already completed (I just thought of another white hat piece of information we forgot to consider), and not hesitate to move the pre-set agenda along (I think we've exhausted the black hats for this one).
After five months of use on the Athena project, average ratings of the 20 design review meeting elements measured before the skills training increased substantially, often an entire satisfaction level. Selected pre-and post-program ratings are shown below in Exhibit 2 (Meeting Efficiency) and Exhibit 3 (Atmosphere for Innovation). A full 90% agreed that their work had improved because of the new approach, 90 % thought their co-workers' work had improved, and 95% predicted they would use the skills in the next four months.

Current methods of calculating the return on Human Resources Development (HRD) initiatives, particularly for soft skills' training, suggest converting qualified participant estimates of improved efficiency into cost savings based on staff salaries, benefits and overhead (SBO) savings (Phillips, 1997). The perceived 40% efficiency improvement is calculated on the projected SBO that the project would have incurred had the team performed at the historical efficiency rate. Based on the team's efficiency improvement estimate, MDS SCIEX interpreted the actual team SBO incurred as 60% of the projected SBO, as follows:
$519 / day - Average team member salary, benefits and overhead (SBO)
$519 x 28 staff = $14,532 / day - Total team SBO
$14,532 x 100 days = $1,453,200 - Actual team SBO for 5 months of product development
$1,453,200 / .60 = $2,422,000 - Projected team SBO, assuming 40% efficiency improvement
Projected SBO - Actual SBO = $2,422,000 - $1,453, 200 = $ 968,800
The investment portion of the return-on-investment calculation includes all costs associated with the innovation skills program, as follows:
$35,261
Considering only the conservative estimate of the impact of the program provided by the participants, the return-on-investment within the 5 months of use of the skills on one project is as follows:
ROI (%) = Net Program Benefits x 100 = (Benefits - Costs) x 100
Program Costs Costs
= $ 968,800 - $35,261 x 100 = $ 933,539 x 100 = 2648%
$35,261 $35,261
This calculation indicates that for every dollar spent on the innovation skills program for the Athena group, MDS SCIEX reaped an additional $26.48, after the cost of the program had been recovered, based on team members estimates of improved efficiency. This is a substantial return. Furthermore, this simplified calculation in no way encompasses the full bottom-line impact of the program.
Consistent improvements in design review meeting efficiency and atmosphere, see Exhibits 2 and 3, are difficult to quantify in dollars, but no doubt had significant effects on the project goals. There is also no direct or easy way to assign a value to any given idea or solution that emerged from the design review meetings as a result of the new innovation tools.
The impact study reveals that meeting agendas were better managed during the Athena project than in previous projects, new ideas were encouraged and explored to a greater extent, team members participated more and behaved in a less adversarial manner, the quality of decisions improved, and ideas were built upon more constructively, among many other improvements. These results indicate that the potential for innovation was enhanced and barriers removed as a result of the application of the tools, setting the stage for improved group effectiveness in innumerable tangible and intangible ways.
The design phase took one and one-half months longer than planned while accommodating 15 change requests and being initially under staffed. The first Athena units were delivered to Manufacturing less than one year from the start of design. Other similarly staffed MDS SCIEX projects would have taken well over a year to accomplish the Athena design effort. The Athena units have a radically different architecture which addresses all of the shortcomings of the Research breadboard units including transportation, safety, and manufacturability. The performance of the commercialized units have exceed their design specifications and that of the top breadboard units. All agency tests were readily meet.
The Six Thinking Hats technique was instrumental in the development of a radically different mechanical architecture for the Athena units. This involved the development of over 36 different high level system architectures and up to eight different concepts for each subsystem. The bulk of the concept work was completed in five weeks when compared to eight weeks on less complicated subsystems on other projects. These project outcomes corroborate the team?s estimation that the Athena product development process was 40% more efficient as a result of the new innovation tools.
Many of the problems discussed earlier with design reviews were avoided with the use of the Six Thinking Hats technique. The project team was not overwhelmed when a given design was found to have problems since the review meeting also provided possible solutions. The general feeling at the end of most design reviews was optimistic even when problems were raised. The biggest endorsement of the tool is the use of the process by other project teams in their design review meetings and in the development of new design concepts.
This paper has demonstrated the following three critical ideas:
Innovation tools can positively impact the product development process. Without the Six Thinking Hats? technique the Athena project would not have succeeded in meeting its aggressive delivery schedule.
The use of innovation tools results in new behaviors which can be measured, hence their effectiveness can be assessed. The Six Thinking Hats? technique has succeed in creating new behaviors related to the design review process and in helping to create a more supportive environment for innovation.
Program evaluation models provide an effective framework for assessing the impact of innovation skills training. The assessment models used to monitor the Athena project have provided a quantitative approach to analyzing the qualitative and quantitative impact of an innovation technique.
The investment in innovation tools to help improve the product development process was a sound investment and the impacts of these tools can be easily assessed and quantified by the users of the new process themselves.
