When developing masterplans for airports, one has to consider a tremendous amount of explicit and implicit variables. Examples are traffic outlooks, airline segmentations and stakeholder requirements. Despite all these variables, we have experienced that in most cases development plans are not in line with the strategic roadmap and the process of truly engaging stakeholders. As a result, the plans are often not sufficient to cope with the modern challenges in aviation. In fact, most masterplans we have assessed are good starting points, but lack quality when it comes to implementation. As a consequence, many projects developed at airports do not add sufficient value to the strategic roadmap. We find that doubtful, and we think airports can do much better. Therefore, we introduce Systems Engineering (SE).
