This chapter presented an overview of the various aspects of the systems implementation process. There are seven different types of testing:
(1) code inspections, in which the code is examined for well-known errors;
(2) walk-throughs, when a group manually examines what the code is supposed to do;
(3) desk checking, when an individual mentally executes the computer instructions;
(4) syntax checking, typically done by a compiler;
(5) unit or module testing;
(6) integration testing, in which modules are combined and tested together until the entire program has been tested as a whole;
(7) system testing, in which programs are combined to be tested as a system and where the system’s meeting of its objectives is examined.
In acceptance testing, users test the system for its ability to meet their requirements, using live data in a live environment.
Testing seems to be an extremely common part of the software application life cycle because it starts at the very beginning of the software application life cycle. And the tests are repetitive and frequent, like the app’s friend, who often comes to play with him. While I’m sure software developers and maintainers don’t find such games very enjoyable, they still have to stick with “games” like “hide-and-seek” and “spot it”.
Testing seems to be a serious and important thing, too. Because the scope of testing is huge, the testing process is strict and the testing requirements are extremely high. In addition, careful planning should be done before testing. The quality of testing is closely related to the quality of software application. It is reasonable to set high standards for testing in order to improve software.
1. There are 6 parts of implementation: coding, testing, installation, documentation, training and support.
2. Management support of the system under development and the involvement of users in the development of are necessary to the success of implementation. It is similar in other cases and project. The management gives the direction and the user can gives the details, which is always necessary in a project.
Hello, Professor,
Here is my answer:
One thing of interest I took away from MSAD chapter 13 “System Implementation” is installation.
Installation is defined as the process of moving from the current information system to the new one. There are four different approaches to installation: direct, parallel, single-location, and phased.
1. Direct installation: The old system is turned off and new system is turned on. It is the cheapest method and creates interest in making the installation successful. However, direct installation can be very risk and requires a complete installation the whole system.
2. Parallel installation: The old system continues to run alongside the new system until users and management are satisfied that the new system is effectively performing its duties, then the old system can be turned off. Therefore, it is less risky than direct installation.
3. Singled-location installation: Comparing with direct and parallel installation, single-location is a middle-of-the-road approach. Instead of converting all of the organization at once, it changes from the current to the new system in only one place over time. Its advantage is that it limits potential damage and cost by limiting the effects to a single site.
4. Phased installation: The new system is brought online in functional components. Different parts of the old and new systems are used in cooperation until the whole new system is installed. Therefore, it is an incremental approach.
Thank you
There are at least two conditions necessary for a successful implementation effort: management support of the system under development and the involvement of users in the development process. Conventional wisdom holds that if both of these conditions are met, you should have a successful implementation. But despite the support and active participation of management and users, information systems implementation sometimes fails.
It should be clear that, as an analyst and as someone responsible for the successful implementation of an information system, you have more control over some factors than others. On the contrary, we need to understand these factors very well because we will have policies involve system users not giving out passwords, changing passwords regularly, keeping operating system and virus detection software updated, and so on. Sound systems security practice demands the effective use of appropriate information technologies as well as the diligent involvement of employees and decision makers in the defense of organization information technology assets.
Hello professor, here is my answer.
The main activities of the system implementation include coding, testing, installation. documentation, training, and support. During implementation, plans are put into effect and the actual testing is performed. The purpose of written test plans is to improve communication among all the people involved in testing the application software. The seven different types of tests include Manual (inspections, desk checking,)and automatic (Syntax checking, unit test, integration test, system test) classifications.
Once the system tests have been satisfactorily completed, the system is ready for acceptance testing, which is testing the system in the environment where it will eventually be used. Alpha testing include the following:
• Recovery testing
• Security testing
• Stress testing
• Performance testing
Overall, once a system is implemented, the organization needs to address internal and external threats to system security. System virus detection and firewalls can only help to a certain extent; system implementation cannot be achieved without proper operational details.
Dear professor, the following is my answer, please check,thanks
In this chapter, many of the activities involved in the implementation phase are
examined. We discussed coding, testing, installation, documentation, user training,Support system installation and successful implementation. Our goal is not to teach you how to program and test systems. Instead, this chapter shows where coding and testing fit into the overall scheme of implementation, especially in a traditional, plan-driven context. This chapter emphasizes the view of implementation as an organizational change process that is not always successful.
If there is a single main point in this chapter, it is that implementation is a complicated process, from managing programmer teams, to the politics that influence what happens to a system after it has been successfully implemented, to planning and implementing useful training and support mechanisms. Analysts have many factors to identify and manage for a successful system implementation. Successful implementation rarely happens by accident or occurs in a totallypredictable manner. The first step in a successful implementation effort may be realizing just that fact. Once systems are implemented, organizations have to deal with threats from both inside and outside the organization to the systems’ security. Although technology such as virus-detection software and firewalls can be employed to help secure systems, good security also requires policies and procedures that guide employees in proper system usage.
Implementation and maintenance are the last two phases of the systems development life cycle. The purpose of implementation is to build a properly working system, install it in the organization, replace old systems and work methods, finalize system and user documentation, train users, and prepare support systems to assist users.
The process of moving from the current information system to the new one is called installation.
1. Direct installation. Changing over from the old information system to a new one by turning off the old system when the new one is turned on. Under direct installation, users are at the mercy of the new system. Any errors resulting from the new system will have a direct impact on the users and how they do their jobs and, in some cases—depending on the centrality of the system to the organization—on how the organization performs its business.
2. Parallel installation. Running the old information system and the new one at the same time until management decides the old system can be turned off.Parallel installation is as riskless as direct installation is risky. Under parallel installa tion, the old system continues to run alongside the new system until users and man agement are satisfied that the new system is effectively performing its duties and the old system can be turned off
3. Single-location installation. Trying out a new information system at one site and using the experience to decide if and how the new system should be deployed throughout the organization. Single-location installation, also known as location or pilot installation, is a middle-of-the road approach compared with direct and parallel installation. Rather than convert all of the organization at once, single-location installation involves changing from the current to the new system in only one place or in a series of separate sites over time.
4. Phased installation Changing from the old information system to the new one incrementally, starting with one or a few functional components and then gradually extending the installation to cover the whole new system. Phased installation, also called staged installation, is an incremental approach. With phased installation, the new system is brought online in functional components; different parts of the old and new systems are used in cooperation until the whole new system is installed.
In Chapter 13, what interests me most is the system testing part of the application phase. Why? Because I think in the system testing phase, you need different people to use the system and get their feedback. For professional IT auditors, we should also participate in the trial testing of the new system, which is beneficial for us to conduct feasibility and consistency audits later. Participating in the test will make us more familiar with the system, and each function, process and working principle of each part will enable us to play with ease in the future audit. If the feedback is not good, the system may be reworked from the design stage, redefining requirements, functions, and so on. Therefore, testing determines whether the system can be used properly.
Hello, professor
Here is my answer:
The thing of interest I took way from MSAD Chapter 13 is types of training methods. Types of Training Methods includes Resident expert, Traditional instructor-led classroom training, E-learning/distance learning, Blended learning (combination of instructor-led and e-learning), Software help components, External sources. I could know how I can learn in the future by learning the types of training methods.
Hi professor,
here is my answer:
One thing I am interested in is the reason why implementation sometimes fails.The implementation phase of the systems development life cycle (SDLC) is the most expensive and time-consuming phase of the entire life cycle. In this chapter, the implementation phase concludes coding, testing, installation, documentation, user training, support for a system after it is installed, and implementation success. Although management support of the system under development and the involvement of users in the development process are successful, it may sometimes fails .That is to say, Information systems implementation is such a complex process that even the most important factors cannot determine the success of the process, and even the most important factors can lead to the failure of the animation. And there are some factors that influence the phase of implementation.
System implementation includes six phases: Coding,Testing,Installation,Documentation,Training and Support.
Testing part interests me most. The purpose of testing is to confirm that the system satisfies requirements.
There are seven different types of tests: (1) inspections (2) desk checking (3) walk-throughs (4) syntax checking (5) unit test (6) integration test (7) system test
All testing must be planned rather that prompted.
When the system tests are satisfactorily done, the system will do acceptance testing, which is for their users’ recognition towards the system.
The most complete acceptance testing includes:
(1) alpha testing: simulated but typical data are used for system testing
(2) beta testing, live data are used in the users’ real working environment
(3) a system audit conducted by the organization’s internal auditors or by members of the quality assurance group.
People is more familiar with the term ’beta testing’ because they usually download applications with beta symbols on it.
The implementation phase of the systems development life cycle (SDLC) is the most expensive and time-consuming phase of the entire life cycle.
Implementing a new information system into an organizational context is not a mechanical process. During implementation, we must be attuned to key aspects of the organizational context, such as history, politics, and environmental demands aspects that can contribute to implementation failure if ignored.
For the implementation process of systems, there are seven different types of testing: (1) code inspections; (2) walkthroughs; (3) desk checking; (4) syntax checking; (5) unit or module testing; (6) integration testing; and (7) system testing.

One thing stick out to my mind is the security factor of system implementation. The security of information systems has become an increasingly important issue for organizations and their management. Hard numbers about losses due to security breaches are difficult to obtain because most companies that have suffered breaches are too embarrassed to admit it, and they are certainly too embarrassed to communicate the actual dollar value of any losses.
In this chapter, I learn about the many activities that the implementation phase comprises. for example testing, installation, documentation, user training, support for a system after it is installed In addition, I learn about providing documentation about the new system for the information systems personnel who will maintain the system and for the system’s users.
the implementation phase of the systems development life cycle (SDLC) is the most expensive and time-consuming phase of the entire life cycle.
The six major activities we are concerned with in this chapter are coding, testing, installation, documentation, training, and support.
The purpose of these steps is to convert the physical system specifications into working and reliable software and hardware, document the work that has been done, and provide help for current and future users and caretakers of the system.
Seven different types of testing: (1) code inspections, in which the code is examined for well-known errors; (2) walkthroughs, when a group manually examines what the code is supposed to do; (3) desk checking, when an individual mentally executes the computer instructions; (4) syntax checking, typically done by a compiler; (5) unit or module testing; (6) integration testing, in which modules are
combined and tested together until the entire program has been tested as a whole; and (7) system testing, in which programs are combined to be tested as a system and where the system’s meeting of its objectives is examined.
four types of installation: (1) direct, when the old system is shut off just as the new one is turned on; (2) parallel, when both old and new systems are run together until it is clear the new system is ready to be used exclusively; (3) single-location, when one site is selected to test the new system; and (4) phased, when the system is installed bit by bit.
two types of documentation: (1) system documentation, which describes in detail the design of a system and its specifications; and (2) user documentation, which describes a system and how to use it for the system’s users.
Security issues: a majority of firms report that they have been victims of external threats, including malware (malicious software) and hacking. Other external security threats include phishing attacks, exploitation of applications, denial of service, and theft of computing or storage devices.
