Figure 2
The illustration is a conceptual process diagram representing “Phase 2: Solution refinement,” as indicated by a large curly bracket along the bottom spanning the full width of the diagram. It contains nine main labeled boxes arranged horizontally from left to right, showing the chronological progression of design, testing, and evaluation activities. On the far left, there is a horizontal arrow-shaped box pointed right and labeled “Design work,” which contains italicized text: “New L S P procedures, integration of I T-systems, packaging design.” Next to this arrow of the design work, to the right, is another rightward arrow box labeled “Empirical activities,” containing the text: “Field test 1, 6 weeks.” Below these two arrow boxes, another long arrow labeled “Theory and conceptual activities” with italicized text: “Bi-weekly meetings.” On the right of these arrow boxes, another rightward arrow box labeled “Evaluation of G D-b” with italicized content: “Two joint workshops, internal evaluations.” Moving to the right, a light gray rectangular box labeled “G D-c:” with bullet points: “Logistics re-processes,” “geographical proximity,” “packaging,” and “rental periods.” Continuing right, the next rightward arrow box labeled “Development work” contains italicized text: “Upgrade of L S P procedures, new customer information, packaging redesign.” To the right, another rightward arrow box labeled “Empirical activities” includes “Field test 2, 8 weeks.” Below these two arrow boxes, another rightward arrow box is labeled “Theory and conceptual activities,” with the italicized content “Bi-weekly meetings.” On the far right side of these arrow boxes, another arrow box is labeled “Evaluation of G D-c,” with the italicized text “Two joint workshops.”Main process steps in the solution refinement phase of our study (Phase 2).
