Software life cycle models itself describes the associated phases of the software life cycle and the order in which each of its phase will be executed (Shelly & Rosenblatt, 2011). Small and Large organizations have now gained so much expertise that they develop their personalized systems for coordinating their requirements which also ensures them quality development. Development of a custom application also requires companies to formulate a thick SDLC manual which involves the basic information and rules followed while developing a particular system. Same is the case when any company makes a decision of purchasing proprietary system off the shelf from an outside vendor. They must critically evaluate their SDLC model which can easily adapt the company’s requirements otherwise management needs to limit some functionalities and designed sub-modules for handling such tasks. 2. Describe the major types and classifications of health care information standards and the specific organizations that develop and regulate these standards. Information and data standards involve major informatics constituents which are required for information flow through a specific health care information system infrastructure. For designing a health care information system certain regularized standards issued by the health care governing bodies are required to be followed. Once these are understood clinical and patient safety systems can be customized for multiple purposes for meeting the wide scope of data collection and their associated reporting requirements. New data standards have also supported effective assimilation of novel trends and discoveries into their decision support systems such as generation of an alert for having a new drug contraindication, and improvement to the care process (nap.edu, 2004). From the basic level data standards primarily involve standardization of data elements which involves defining, deciding the presentation model through designation of data types or terminologies and lastly determine how to encode a particular set of data for transmission. Some of the renowned health care data standard organizations are American Society for Testing and Materials (ASTM) responsible for architecture, storage, content, security and communication protocols for health care decision making, Current Procedural Terminology (CPT) which has intended for medical billing procedures, Digital Imaging and Communications in Medicine (DICOM) responsible for transmission of medical imaging equipment and their connectivity and many others (aspe.hhs.gov, 2013). 3. Discuss the need for, and identify methods of, accomplishing the security of information systems. The basic aim of an information system security procedure revolves around protecting the organization’s information by reducing the threat of risk and loss of confidentiality, integrity and accessibility of all that information to an agreed level. The need for having a good information security system ...Download file to see next pagesRead More
