Abstract This paper defines the Software Development Life Cycle phases specifically the Waterfall method with a review of tasks to improve the quality of datasets throughout the cycle. It includes recommendations of actions to be performed for full optimization for enhancing performance from data quality assessment. Although full optimization may be reached throughout the process of SDLC, continued maintenance must be in sued to properly retain the database error-free and protected. An evaluation of three methods and activities to ensure maintenance

Automating process controls to ensure systems correctly process and record information. (FFIEC IT Examination Handbook InfoBase - Design Phase., n.d.). Quality management techniques that improve quality assessments include error detection, process control, and process design. These processes detect missing values, improve recurring errors, and help optimize effeciency. (Even, A., & Shankaranarayanan, G., 2009).
Three Maintenance Plans and Three Activities to Improve Data Quality Three types of maintenance plans include: preventative, corrective, and adaptive maintenance which improve the data quality. Activities to improve data quality include database backups, integrity checks, optimizing the index. Preventative maintenance incorporates creating and continuously maintaining daily and/or weekly backups for data loss prevention, corrective maintenance ensures system errors are corrected. One activity associated to corrective maintenance includes resolving deadlocks, which occurs when two or more tasks permanently block each other. Adaptive maintenance includes enhancing system and database performance via based on utility assessments and optimized queries to improve performance. (Coronel, Morris, & Rob., 2013).
Methods for Planning Proactive Concurrency Control and Lock Granularity Concurrency issues revolve around conflicts that occur when simultaneous tasks are performed on multiple systems, the conflict may cause
Developing software is far from an exact science and without a structured system to guide the process a project is likely to fail. Defining and adhering to a Software Development Life Cycle (SDLC) early in the project will help to guide the development of a new information system. In addition to having the structure for the development team to work within a defined and agree upon SDLC will help to set the proper expectations for deliverables with the stakeholders and customer(s). Smith Consulting has been given the task of creating a Frequent Shopper program for Kudler Fine Foods. As a result Smith Consulting needs to decide on which SDLC will work best for this project. In addition to selecting a SDLC to use Smith Consulting will
Process Quality is the second approach we use with a concentration on validating that the policies and procedures implemented to maximize quality and customer service are being followed. We also use Process Quality to make sure the implemented procedures are the most appropriate to achieve the goals. This approach is better known as “continuous improvement” and was made famous by Edward Deming. Deming taught that by adopting appropriate principles of management, organizations can increase quality.
The quality control approaches below are suggested critical actions that can be audited concurrently with the process flow or management over a period of time. An audit may be performed on a random sample of requests to determine if critical processes
As employees of an organization we are required to ensure the welfare of the same at all times. Sometimes we see and analyze certain processes carried out and it is understood that there is any way in which these processes can be improved. It happens that we are not prepared to report that such changes are needed for reasons that are varied. There are positions in companies that are responsible for ensuring that all processes, products and services offered comply fully with the expectations of customers. The so-called "quality controls" are the order of the day in different industries thus minimizing the losses that come when we could make a claim for defective product or service. The following provides an example of
The second section in this lab builds on Lab 3. It is best to complete Lab 3 first before
Proper Maintenance of the system or Database (DB) with timely and weekly updates to correct any Database (DB) issues.
The Quality Management Team will make sure that quality is measured, monitored and defects identified, and corrective action is taken. The project team will perform formal work product and deliverable review actions, and formal testing activities as outline in the project schedule and the QA documents. Other functionality requirements like trace-ability activities that are identified in the methodology and tasked in the project schedule are also Quality Control processes that will assist in monitoring project results to make sure they comply with system user needs and expectations. The project risk management is another quality control activity that will be used on this project.
The Company has developed a Quality Management System (QMS) in order to achieve these objectives. The system defines the Company’s technical and administrative policies and procedures. The Company will implement the QMS through training of new Associates, regular refresher training and internal audits. The Company will continue to improve the Quality Management System over time. This will be done by annual review process and regular revisions as improvements and/or corrections are identified.
For years companies have turned to IT (Information Technology) to make things easier and reduce the waste of paper and human computers. When companies find themselves regularly maintaining and upgrading their software is there room for Lean in software development? With business requirements perpetually changing can a business get to the place where the system is good enough? Cost cutbacks, faster time-to-market, improved products and differentiated services are now the essential pillars in managing any software development process. The shift has been to move away from the customary Systems Development Life Cycle (SDLC) approach to newer standards that provide higher certainty and decreased risk by ensuring that business deadlines are met. (Pillai, A., Pundir, A., & Ganapathy, L., 2012, p. 107).
Carrying out improvements necessary to meet standards of quality are a major task within an organization. Quality should involve incremental improvement and Current performance must be measured to establish a baseline to determine whether criteria for improvement was met A process should also be in place which continuously monitors areas of improvement on a routine basis which will determine whether improvement has occurred. For a system to succeed it must address areas such as infrastructure, data collection, data reporting, data analysis, and a process capable of identifying potential shortfalls (Joshi, Ransom, Nash, & Ransom, 2014).
The data and the values of the sensitivity scores would be collected at the general dental practice by the trained dentists who will report to the second investigator responsible for the overall collection of the data. Direct patient examination would be carried out at base line, immediately, 3, 6 and 9 months post application using visual analogue scale for tactile stimuli response and Schiff cold air sensitivity scale for standard cold air blast.

A relational database is a collection of data which organized into a set of tables that can be accessed in multiple ways without having to reorganize the tables’ oftenly.Relational Database was proposed by Edgar Codd around the time 1969.It has become prevalent for commercial applications. In the 20th century there were countless Relational Database System (RDBMS) take for instance: IBM.DB2 and Oracle.
All information collected in this paper through different authorized journals accessed through digital library by accessing different sites for example Emerald insight, Springer, Jstor etc and through different books of Quality Management and Process reengineering. Some books are taught by different universities as a full subject for example Allama Iqbal University has included Total Quality Management as course book under code 5575 at Master level. Likewise NUST and NUML universities have also included this subject at MS level. So information collected through these universities recommended books and class lectures. Information for BPR collected through Hammer & Champy Book Reengineering the Corporation and also from the book
Stryker is a global medical device manufacturing company. The Instruments Division is located in Kalamazoo, Michigan. It was founded by Dr. Homer Stryker, an orthopedic surgeon. Dr. Stryker discovered that certain medical devices were not meeting his patient’s needs. Because of this, Dr. Stryker decided to invent new ones. The devices he invented were successful, and the interest in Dr. Stryker’s products began to grow. As a result, in 1941 he decided to start a company to produce them.
