Appendix-A Interview guide – warehouse managers 1. Would you please introduce yourself, your background and experience in warehousing and material handling? 2. Would you please give a brief introduction about your company and its business? 3. If you want to rank the issues and problems in your warehouse, what would be the problems and their ranking? (These concerns may fit into any of the aspects of your business, for instance physical structure, performance evaluation, cooperation with other companies and departments, warehousing operations, etc.) 4. If you compare your current problems and priorities with problems and priorities you had some years ago, what would be the difference? What is the reason of this change (if any)? 5. What do you expect to be your future concerns? How do you see the future of the warehousing business? Interview guide – consultants 1. Would you please introduce yourself, your background and experience in warehousing and material handling? 2. What type of consulting services do you offer? 3. According to your experience what are the main (or common) issues that warehouses come to ask consultancy services to address? 4. If you compare current problems and priorities of your clients with the problems and priorities they had some years ago, what would be the difference? What is the reason of this change (if any)? 5. What future challenges do you see for the warehousing business? In another words, what do you predict to be the main trends of this area in future? 6. According to your experience with different clients, do you see any issue that is usually neglected by warehouse managers that you think should not be overlooked?
