2 companies experiencing problems because of an error in the software they are currently using or because of a software upgrade.
NASA Mars Climate Orbiter – It is a 338 kg robotic space probe that is capable of determining the distribution of water in mars, it could read atmospheric condition, pressure, and temperature, monitor the changes in martian surface due to wind and other atmospheric factors. It was launched aboard the launch vehicle Delta II 7425 at NASA’s space launched complex 17A, Cape Canaveral Air force Station, Florida USA on December 11, 1998 and began its 286 day journey thru mars. On September 23, 1999, fired itself into orbit of mars. After the planned orbital insertion maneuver the communication was lost between the control center and the climate orbiter. Since then they’ve lost the orbiter with the cost of $125 million. Investigation began after the incident. Investigation reveals that the unit of measurement mismatch is the cause of losing the orbiter. The Lockheed Martin Engineering Team has used English unit of measurement for the navigation of the orbiter while the NASA’s flight team used the metric system. Failure to conversion of units from English to Metric was the mishaps and causes to loss the orbiter.

Washington State Department of Corrections Software Glitch – There are many software glitches that been around for years since the boom of computer age. One of the example is the Washington State Department of Corrections Software Glitch. According to www.npr.org, the software glitch was due to the Supreme Court ruling that required the Corrections Department to apply good-behavior credits earned in county jail to state prison sentences. Instead of making the calculation of sentence more accurate, the glitch cause the sentence time of the prisoner to become short. The number of prisoners that was release was ranging from 3000 to 3200. The Department of Corrections officials don’t have the specific list of prisoner who were let out earlier than expected sentence days but some prisoners who are identified, they resume to serve their sentences. The glitch only found out after 13years since the implementation of the said system software when the family of a prisoner conduct their own calculation of the sentence and found out that their family member who is a prisoner was credited with too much time.

What is Capability Maturity Model Integration (CMMI)?
The Capability Maturity Model Integration (CMMI) developed by the Software Engineering Institute. The CMMI can guide the process of improvement across the project,division or an entire organization. CMMI provides guidelines for processes improvement, An integrated approach to process improvement, Embedding process improvements into a state of business as usual, A phased approach to introducing improvements. The CMMI models consists of three overlapping disciplines which is CMMI for Development, CMMI for Services and CMMI for Acquisition.
Provide at least 2 companies that are currently using CMMI model.
Minac – It is a global outsourcing business solution leader with more than 35 years of process, domain and technology expertise. The company always believes in maintaining high-quality standards and processes. The company’s processes were already complaint with CMMI for Development, version 1.2.

Accenture is a leading professional services company, providing a broad range of services and solutions in strategy, consulting, digital, technology and operations. The Accenture tech hub in the philippines has achieved a Capability Maturity Model Integration (CMMI) Level 5 rating in both CMMI for Development v1.3 and CMMI for Services v1.3. CMMI is a process improvement model that provides organizations with the essential elements of effective processes that ultimately improve their performance. An appraisal at maturity level 5 indicates that the organization is performing at an “optimizing” level. At this level, an organization continually improves its processes based on a quantitative understanding of its business objectives and performance needs. The organization uses a quantitative approach to understand the variation inherent in the process and the causes of process outcomes.
