The manager then asked her assistant, Ann, to investigate the matter and to report her recommendations. Ann's first task was to determine what problems were generating the complaints. The majority of complaints centered on five defects: underfilled packages, a missing label, spills/mixed items, unacceptable taste, and improperly sealed packages. Next, she took samples of dinners from the two production lines and examined each sample, making note of any defects that she found. A summary of those results is shown in the table. The data resulted from inspecting approximately 800 frozen dinners. What should Ann recommend to the manager?

- Case Study 3 – Miscommunication The Space Shuttle Columbia disaster While reentering Earth’s atmosphere the shuttle unexpectedly disintegrated, resulting in the death of all seven astronauts on board. The cause was later discovered to be damage to thermal shielding tiles from impact with a falling piece of foam insulation of an external tank during launch. It was the seventh known instance of this particular piece breaking free during launch. NASA’s investigation team found melted aluminum on the thermal tiles and inside edges of the left wing of the spacecraft, supporting the notion that the Columbia’s destruction was due to hot gases that penetrated the damaged spot on the wing. Mission control deemed that foam shedding was a not a safety factor prior to launch, believed damage of the shuttle panels were not a significant issue. It was not until January 24, 2003, that mission control had classified the damage as a problematic issue. These missteps in communication between mission…arrow_forwardSanjeevini is a 100 bed hospital established 10 years ago and is performing well.
