SDLC Analysis Phase

System requirements studied and structured?

Review notes

Within 48hr of interview

Enterprise-wide systems

are large, complex systems that consist of a series of independent system modules

Reasons for outsourcing

cost advantage, insufficient capacity, lack of expertise, quality

Three key principles shared by the Agile Methodologies

- Focus on adaptive rather than predictive methodologies - Focus on people rather than roles - Focus on self-adaptive processes

Examples of company outsourcing

- Payroll - Information Technology (IT) - Running your applications at your site

Major Phases of the SDLC

-Planning -Analysis -Design -Implementation -Operations and Maintenance

Outsourcing

A company running a computer application for another organization

Project Management

A controlled process of initiating, planning, executing, and closing down a project.

Project

A planned undertaking of a series of related activities to reach an objective that has a beginning and an end.

SDLC Planning Phase

A presentation of why the system should or should not be developed by the organization is given.

Systems development methodology

A standard process followed in an organization to conduct all the steps necessary to analyze, design, implement, and maintain information systems.

Deliverable

An end product of an SDLC phase.

SDLC Maintenance Phase

An information system systematically repaired and improved?

Forms Importance

Because they explain what data flows in or out of a system

Completion of the implementation phase

Code, documentation, training procedures, and support capabilities

Feasibility study

Conducted by the project manager, involves determining if the information system makes sense for the organization from an economic and operational standpoint.

Completion of analysis phase

Description of current system and where problems and opportunities are with a general recommendation on how to fix, enhance, or replace current system

Completion of planning phase

Detailed steps, or work plan, for project

Conflict Management

Managing conflict within a project team to assure that conflict is not too high or too low

Information analyst can locate in documents during the analysis phase

Problems with existing system, business rules and data handling procedures, key people and roles in the current system, opportunities to meet new needs with critical information

Documentation

Provide by Project Workbook, new team members require to assimilate project tasks quickly.

Impertinence

Systems analyst is questioning everything

Project manager

Systems analyst with a diverse set of skills—management, leadership, technical, conflict management, and customer relationship—who is responsible for initiating, planning, executing, and closing down a project.

Nominal Group Technique (NGT)

Technique in which participants each suggest ideas through a series of rounds and then discuss the items, eliminate redundancies and irrelevancies, and agree on the importance of the remaining items. Ideas for new features in a system.

Systems Development Life Cycle (SDLC)

The life cycle can be thought of as a circular process in which the end of the useful life of one system leads to the beginning of another project to develop a version of or replace an existing system

Work Breakdown Structure (WBS)

The process of dividing the project into manageable tasks and logically ordering them to ensure a smooth evolution between tasks.

Project Initiation

The project manager performs several activities to assess the size, scope, and complexity of the project and to establish procedures to support subsequent activities

Drawback for Prototyping

There is typically no formal documentation created.

Baseline Project Plan

You should monitor your progress while executing

Application software

would be classified as software designed to support the payroll function.
