to medium sized projects.
Moreover, now it’s an age of computers of and automating such an organization gives
the better look.
The systems development life cycle is a project management technique that
divides complex projects into smaller, more easily managed segments or phases.
Segmenting projects allows managers to verify the successful completion of project
phases before allocating resources to subsequent phases.
Software development projects typically include initiation, planning, design,
development, testing, implementation, and maintenance phases. However, the
phases may be divided differently depending on the organization involved.
For example, initial project activities might be designated as request,
requirements-definition, and planning phases, or initiation, concept-development, and
planning phases. End users of the system under development should be involved in
reviewing the output of each phase to ensure the system is being built to deliver the
The Initiation Phase begins when a business sponsor identifies a need or an
The purpose of the Initiation Phase is to:
Identify and validate an opportunity to improve business accomplishments of the organization or a deficiency related to a business need. Identify significant assumptions and constraints on solutions to that need. Recommend the exploration of alternative concepts and methods to satisfy the need including questioning the need for technology, i., will a change in the business process offer a solution? Assure executive business and executive technical sponsorship. The Sponsor designates a Project Manager and the business need is documented in a Concept Proposal. The Concept Proposal includes information about the business process andthe relationship to the Agency/Organization. Infrastructure and the Strategic Plan. A successful Concept Proposal results in a Project Management Charter which outlines the authority of the project manager to begin the project.
Careful oversight is required to ensure projects support strategic business
objectives and resources are effectively implemented into an organization's enterprise
Construction of executable prototypes is encouraged to evaluate technology to support the business process. The System Boundary Document serves as an important reference document to support the Information Technology Project Request (ITPR) process. The ITPR must be approved by the State CIO before the project can move forward.
The planning phase is the most critical step in completing development,
acquisition, and maintenance projects. Careful planning, particularly in the early
stages of a project, is necessary to coordinate activities and manage project risks
effectively. The depth and formality of project plans should be commensurate with the
characteristics and risks of a given project. Project plans refine the information
gathered during the initiation phase by further identifying the specific activities and
resources required to complete a project.
A critical part of a project manager’ sjob is to coordinate discussions between
user, audit, security, design, development, and network personnel to identify and
document as many functional, security, and network requirements as possible. During
this phase, a plan is developed that documents the approach to be used and includes
a discussion of methods, tools, tasks, resources, project schedules, and user input.
Personnel assignments, costs, project schedule, and target dates are established.
A Project Management Plan is created with components related to acquisition
planning, configuration management planning, quality assurance planning, concept of
operations, system security, verification and validation, and systems engineering
This phase formally defines the detailed functional user requirements using
high-level requirements identified in the Initiation, System Concept, and Planning
phases. It also delineates the requirements in terms of data, system performance,
security, and maintainability requirements for the system. The requirements are
defined in this phase to alevel of detail sufficient for systems design to proceed. They
need to be measurable, testable, and relate to the business need or opportunity
identified in the Initiation Phase. The requirements that will be used to determine
acceptance of the system are captured in the Test and Evaluation MasterPlan.
The purposes of this phase are to:
Further define and refine the functional and data requirements and document them in the Requirements Document, Complete business process reengineering of the functions to be supported (i., verify what information drives the business process, what information is generated, who generates it, where does the information go, and who processes it), Develop detailed data and process models (system inputs, outputs, and the process. Develop the test and evaluation requirements that will be used to determine acceptable system performance.
This document receives a rigorous review byAgency technical and functional representatives to ensure that it satisfies the business requirements. Concurrent with the development of the system design, the Agency Project Manager begins development of the Implementation Plan, Operations and Maintenance Manual, and the Training Plan.
The development phase involves converting design specifications into executable programs. Effective development standards include requirements that programmers and other project participants discuss design specifications before programming begins. The procedures help ensure programmers clearly understand program designs and functional requirements. Programmers use various techniques to develop computer programs. The large transaction oriented programs associated with financial institutions have traditionally been developed using procedural programming techniques. Procedural programming involves the line-by-line scripting of logical instructions that are combined to form a program completion of the previous stages is a key factor in the success of the Development phase. The Development phase consists of:
Translating the detailed requirements and design into system components. Testing individual elements (units) for usability. Preparing for integration and testing of the IT system.
Subsystem integration, system, security, and user acceptance testing is conducted during the integration and test phase. The user, with those responsible for quality assurance, validates that the functional requirements, as defined in the functional requirements document, are satisfied by the developed or modified system. OIT Security staff assess the system security and issue a security certification and accreditation prior to installation/implementation.
Multiple levels of testing are performed, including:
Testing at the development facility by the contractor and possibly supported by end users
Testing as a deployed system with end users working together with contract personnel
Operational testing by the end user alone performing all functions. Requirements are traced throughout testing,a final Independent Verification & Validation evaluation is performed and all documentation is reviewedand accepted prior to acceptance of the system.
This phase is initiated after the system has been tested and accepted by the
user. In this phase, the system is installed to support the intended business functions.
System performance is compared to performance objectives established during the
planning phase. Implementation includes user notification, user training, installation of
hardware, installation of software onto production computers, and integration of the
system into daily work processes. This phase continues until the system is operating
in production in accordance with the defined userrequirements.
The system operation is ongoing. The system is monitored for continued
performance in accordance with user requirements and needed system modifications
are incorporated. Operations continue as long as the system can be effectively
adapted to respond to the organization’s needs. When modifications or changes are
identified, the system may reenter the planning phase.
The purpose of this phase is to:
Operate, maintain, and enhance the system.
