32 CHAPTER 4 OPERATIONAL BEST PRACTICES CASE STUDY Excel is perhaps the most classic example of such software. Since it is well-known and understood by most people, employees can start using it immediately and deliver value to the organization. The files created in Excel can be easily shared with anyone in the organization or the broader industry, and everyone will be able to access its contents and insights. While insights in Excel can be more efficiently presented using a business intelligence or analytics platform, this requires continuous maintenance and integration with the organization's various tools and databases. If the organization has the capabilities and expertise to do this, the end results can be great. However, if it is done as a one-off effort or using an external consultant, it is at risk of falling apart.
