There is a lack of surveys in large web development enterprises to determine: the level of adoption of web engineering practices and capability maturity model integration (CMMI) in these enterprises. Therefore, we need a survey in large enterprises to improve their web development processes and overcome their problems during the development process. We focus in this research on answering four questions: What are the characteristics of developers working in large enterprises? What are the properties of web development processes adopted by large enterprises? What are the symptoms that large enterprises face during web development? And finally, what are levels of usage of CMMI and web engineering practices by these enterprises. A survey has been conducted in this research based on questionnaires in large enterprises in Jordan to answer the above questions. According to survey results, we noticed that: two of web engineering practices such as tools and technology, and standards and procedures are partially adopted, whereas organizational issues, web metrics, and control of development process are barely used by these enterprises. We also noticed that the majority of the respondents have not previously participated in CMMI activities. Finally, recommendations are provided to improve web development processes and overcome identified problems in these enterprises.
