Identify considerations of primary importance in each step. Diagram the cycle and discuss its operation. Identify, diagram and discuss implementation alternatives? Could you please rewrite this answer by using own words and the two diagram that help me understand the steps and alternative and explain this answer clearly

Planning – establishing the plans for creating an IS by:

Defining system to be developed – based on the systems prioritized according to the organization’s critical success factor (CSF), a system must be identified and chosen

Defining project scope – a high level of system requirements must be defined and put into a project scope document. Scope creep.

Developing project plan – all details from tasks to be completed, who completed them and when they were completed must be formalized

Managing plan –stay on track, creating project milestones and controlling feature creep which allow you to add to the initial plan (Haag, 2007)

Analysis – the end users and IT specialists collaborate to collect, comprehend, and logistically formalize business requirements by:

Gathering the business requirements' – IT specialists and knowledge workers collaborate in a joint application design (JAD) and discuss which tasks to undertake Development – executing the design into a physical system by:

Building the technical architecture

purchasing and installing the material needed to build the system (HST)

Building the database and programs –

the IT specialists write programs which will be used on the system (Haag, 2007)

Analyzing the requirements – business requirements are prioritized and put in a requirements definition document where the knowledge worker will approve and place their signatures (Haag, 2007)

Design – this is where the technical blueprint of the system is created by:

Designing the technical architecture. Choosing architectural designs for:

Telecommunications

Hardware

Software

Systems modeling – graphically creating a model from graphical user interface (GUI), GUI screen design, and databases, to placement of objects on screen (Haag, 2007)

Development – executing the design into a physical system by:

Building the technical architecture

purchasing and installing the material needed to build the system (HST)

Building the database and programs –

the IT specialists write programs which will be used on the system (Haag, 2007)

Testing – test the developed system

Write test requirements – tests are conducted by comparing expected outcomes to actual outcomes. If these differ, backtracking to the development stage must occur (Haag, 2007).

Test as close to operating conditions as possible.

End user testing. End users can and will break it if possible. Nothing is idiot proof; the idiots win every time

Implementation – the systems are placed and used in the actual workforce:

The user guide is created

Other necessary documentation completed

Training is provided to the users of the system (Haag, 2007)

Maintenance – keeping system current with the changes in the organization and technology. Ensuring it meets goals of the organization by:

Building a help desk to support the system users – having a team available to aid technical difficulties and answer questions

Implementing changes to the system when necessary (O’Brien, 2007).

Evaluating system accomplishment of business requirements

Systems Implementation Alternatives

Direct – turn off the old system and turn on the new system. Lower cost (only support one system at a time) but high risk of failure.

Parallel – Keep old system running until new system is debugged and functional. Low risk because old system is fallback but high costs of supporting and operating two systems at once.

Phased – install one component of new system, debug it and turn that component off in old system. Do one part at a time starting with less critical components. More secure than direct but less costly than parallel

Explanation / Answer

1-System Planning

The Planning stage is the most essential advance in making an effective framework, amid this stage you choose precisely what you need to do and the issues you're endeavoring to explain, by:

Characterizing the issues, the destinations and the assets, for example, faculty and expenses.

Concentrate the capacity of proposing elective arrangements subsequent to meeting with customers, providers, advisors and workers.

Concentrate how to improve your item than your rivals'.

In the wake of breaking down this information you will have three options: build up another framework, enhance the present framework or leave the framework as it seems to be.

2-System Analysis

The end-client's prerequisites ought to be resolved and reported, what their desires are for the framework, and how it will perform. An achievability study will be made for the venture too, including deciding if it's authoritatively, financially, socially, mechanically plausible. it's essential to keep up solid correspondence level with the customers to ensure you have an unmistakable vision of the completed item and its capacity.

3-System Design

The plan stage comes after a decent comprehension of client's prerequisites, this stage characterizes the components of a framework, the parts, the security level, modules, engineering and the distinctive interfaces and sort of information that experiences the framework.

A general framework configuration should be possible with a pen and a bit of paper to decide how the framework will look like and how it will capacity, and after that a point by point and extended framework configuration is created, and it will meet all useful and specialized necessities, intelligently and physically.

4-Implementation and Deployment

This stage comes after an entire comprehension of framework necessities and particulars, it's the real development process subsequent to having a total and delineated plan for the asked for framework.

In the Software Development Life Cycle, the real code is composed here, and if the framework contains equipment, at that point the execution stage will contain setup and tweaking for the equipment to meet certain prerequisites and capacities.

In this stage, the framework is prepared to be sent and introduced in client's premises, prepared to end up running, live and gainful, preparing might be required for end clients to ensure they know how to utilize the framework and to get comfortable with it, the usage stage may take quite a while and that relies upon the multifaceted nature of the framework and the arrangement it presents.

5-System Testing and Integration

Bringing diverse segments and subsystems together to make the entire coordinated framework, and after that Introducing the framework to various contributions to get and investigate its yields and conduct and the way it capacities. Testing is ending up increasingly vital to guarantee consumer loyalty's, and it requires no information in coding, equipment arrangement or plan.

Testing can be performed by genuine clients, or by a group of specific work force, it can likewise be precise and computerized to guarantee that the real results are contrasted and measure up to with the anticipated and wanted results.

6-System Maintenance

In this stage, intermittent support for the framework will be completed to ensure that the framework won't wind up old, this will incorporate supplanting the old equipment and consistently assessing framework's execution, it additionally incorporates giving most recent updates to specific parts to ensure it meets the correct norms and the most recent advances to confront current security dangers.

These are the fundamental six periods of the System Development Life Cycle, and it's an iterative procedure for each undertaking. It's critical to specify that amazing correspondence level ought to be kept up with the client, and Prototypes are imperative and accommodating with regards to meeting the necessities. By building the framework in short emphasess; we can ensure meeting the client's necessities previously we construct the entire framework.

Numerous models of framework improvement life cycle came up from sparing exertion, cash and time, notwithstanding limiting the danger of not meeting the client's prerequisite toward the finish of task, some of postulations models are SDLC Iterative Model, and SDLC Agile Model.
