Peoplesoft Integrations and the Software Development Life Cycle

Software Development Life Cycle (SDLC)

The process of planning, creating, testing, and deploying software is called Software Development Life Cycle or SDLC. Different tasks to be performed in each step of the software development process are explained well in SDLC. Different phases of SDLC are planning, requirements, design, development, testing, deployment, and maintenance.

There are several phases in the lifecycle of software which are given below:

1. Requirement Phase
2. Analysis Phase
3. Design Phase
4. Development Phase
5. Testing Phase
6. Deployment & Maintenance Phase

1. Requirement Phase

This is the first and fundamental step in the Life Cycle of Software Development. It starts with gathering the requirements from customers or clients. In most organizations, this role is taken care of by Business Analysts. A Business Analysts interacts with the customer/clients, set up daily meetings, document the requirements in Business Requirement Specifications (or Simple Business Specification), and hand over the final documented requirement to the development team. It is the responsibility of Business Analysts that every detail is captured and documented and also to make sure that everyone clearly understands the client requirements.

2. Analysis Phase

Once the Requirement Gathering phase is completed, the next task is to analyze the requirements and get them approved by the customer/clients. This is achieved through Software Requirement Specification (SRS), which consists of all the requirements gathered and developed during the Requirements Gathering phase. This phase is mainly done by Project Managers, Business Analysts, and Consultants.

3. Design Phase

Once the Analysis Phase is over, next comes the need to come up with the most accurate, robust, efficient and cost-effective architecture of the product that needs to be developed. Usually, more than one design is proposed in this phase, and the best one is selected based on different parameters such as robustness, durability, timeline, cost-effectiveness, and many more! The different design architecture is generally documented in Design Document Specification or DDS.

This phase consists of 2 design approaches:

Low-Level Design: This task is performed by the Senior Developers where they specify the function of each module of the product architecture that has to be developed.

High-Level Design: This task is performed by Architects/Senior Architects where they design different possible architectures of the product that has to be developed.

4. Development Phase

This phase is where the actual implementation of programming languages and different frameworks are being utilized for the development of the product. In this phase, all developers are involved. Developers are expected to follow certain predefined coding standards and guidelines; they are expected to complete the project modules within the defined deadline for the project. This phase is also the longest and one of the most critical phases in the Software Development Life Cycle. This phase is documented as a Source Code Document (SCD).

5. Testing Phase

Once the Development phase is completed, the next step is to test the developed software. The developed software is sent to the testing team, where they conduct different types of testing thoroughly on the software and look for defects. If any defect is found, the testing team records and document which is again sent back to the development team for error removal. This role is taken care of by Software Testers and Quality Analysts of the company. The testing team has to make sure that each component of the software is error-free and it works as expected.

 

6. Deployment and Maintenance Phase

After the testing phase is over, the first version of the software is deployed and delivered to the customer for their use. Once the customer starts using the developed software, there is the scope of bug fixing that was not detected during the testing phase as when a large group of end-users starts using the software; there could be some probability that few boundary cases might have been missed. There is also scope for upgrading the software with newer versions and the latest security patches and technologies. And finally, there is also scope for enhancement of the software by adding more features into the existing software.

 

The following activities will be part of the Implementation/deployment.

• We will provide deployment packages which include Instructions to install and test, User Authorization/Permissions, Firewalls white-listings, Trouble shooting tips.
• Import the project(s) in Peoplesoft.
• Enable Permissions for all Service Operations listed in the package.
• Build all the records listed in the project
• A user assigned to Integration Ports have been assigned appropriate security.
• The third-party IP address are white-listed in the Peoplesoft hosting environment.
