After only a little more than a month Jack in the Box Inc. chief information officer Carlson Choi has exited the company, officials said Friday. No reason for his departure was given. Darin Harris, Jack in the Box’s CEO, said in a statement that Choi and the company mutually decided to part ways.  “We wish Carlson the best and have already started our search for a long-term CIO that will help Jack in the Box reach its full digital potential as we take this brand into its next growth chapter,” said Harris. Choi joined the San Diego-based quick-service chain on May 3 to replace Andrew Martin, who left the position in April. Choi served previously as global chief digital officer and chief information officer for Jollibee. Since joining Jack in the Box last year, Harris has been restructuring the executive team bringing in a new chief financial officer and chief marketing officer. Most recently, the company hired former Mooyah president Tony Darden as chief operating officer. Jack in the Box operates and franchises about 2,228 restaurants in 21 states and Guam. –Source: NRN.
