Question

Using your own words as much as possible, describe the major phases of the SDLC, including the major deliverables in each step.

Answer 1

SOFTWARE DEVELOPMENT LIFE CYCLE:

SOLC: SOLC can be expanded as Software develoment life cycle. It is a process followed by the software industries To design, implement and test the software Modrets. =) Basically SOLC has sin major phases. while each phase has its own deliverables which serve as the input for the next phase Six phases of SDLC O Requirement gathering ¿ analysis © Design Implementation & Coding 4 Terting ③ Deployment @ Mairstenence Requirements maintenence) gathering Analysis SOLC Design Deployment (Implementation Coding

PHASE1:#1     REQUIREMENT GATHERING AND ANALYSIS:

O Requirement gathering & Analysis - Requirement gathering and Analysis is the Sondamental phax of software development - Bussiness requirement and specifi are gathered during this phase - TOP level management of Company & prorect managers, directors and other stake- holders are mainly incorked in gathering Depuirement of software. once the requirements are gathered it will be analyzed by the person of group of individuals to make sure the possibility of incorporating Software development with gefuirement gathered. Deliverables o Business Reruirement Documen -lation Coro), Software Recurement Specification (SRS), Technical Requirement Specifications (TRS) documents are created Which serves as input for next phase i.e. Design phase

PHASE#2     DESIGN:

2. Design - The design phase is the second phase of SOLC. I System Architeuticle is designed during this phase & Design architects, Bussines analyst are mainly involved in drafting the design of software a) High level design (H2O) and low-level Design (LLD) are designed with the help of the requirement gathered in first Phase no - Some design documents that helps in developing the software effectively a uvecase Diognom) b) class Diagram C) E-R diaglan c) Component Diooreen e) wolk flow diagram of activites diagram - The above destin documents serve as inpect for next phare le implementation & Coding Deliverables: System Archietecture, HLD, LLD, Detailed design specification CDDS), are created and serves as input for onent phase - Implementation & Coating

PHASE#3 IMPLEMENTATION/CODING:

3) Implementation, Coelings - Coding is the third phase of SPL - Detailed design specifications are used as input by developers to build Software product & The main focus of this so phase if development & Entire design is broken inte modules and developers will work on individual modeles, nen they integrate the seperate modules inte one system finally - Coding standards & quidlines are followed while developing the products » Companies use the Coding Conguages like TAVA, CAT, CH.PHP ete based on their need & knowledge & when two developers are working on the same software at the same time, Code merge of allomplished without much.. havle by following proper Coding guidnines Deliverable: Working software is developed which serves as inpect for next phase. Testing

PHASE#4    TESTING:

4) Testing : Testing is the fourth phase of SOLE - Working software used for testing to - The main forces of this phase is to ensure the qualiter and to validate the test againest Customer requirements te make sure that the product satisfies the customer needs. - Test Cases and Test scripts are cesed for testing to validate the requirements. s) some examples of testings a) System Testing 6) Component testing c) System Integration Terting d) Component Integration Testing e) performance testing f) Alleptance testing & Software prodrect bugs, issues, defects are tracked and retested Intil the product achieves the quality Deliverables: Test Summary Report, Test Results, QA plan, Revised bugs list are Sieboilted which serves as input for next Phase - Deployment

PHASE#5    DEPLOYMENT:

once ware produtor usage to settware 5) Deployment - Deployment is the fifth phase of SALE & once the product is successfully tested, the Software produit : Can be released / Deployed to customers for usage . If my changes geruired for seittwoore is, also Conveyed to team so that the changes will be incorrnated in their Siebsement releases - Beta testing is done at Customer's site befole fincel deployment to ensure the prodied meets Customer requirements the - Beta Testing feedbacks and issues are terorted back to the engineering tom te ensure they address them sooner Plates & once the issues are fixed, then product is finalized and will be ready for final deployment out Deliverables Deployed software, Customer gleview, Live prodieetion environment and Data are submitted which serves as input for rent phase - Maintenenee

PHASE#6   MAINTENANCE:

6) Maintenance - Maintenance is the sixth phase of the SDLC - once the product is used by Customer The issues faled by them are addressed during the maintenance phase. =) Support provided for deployed Software is called Maintenance - Handling the bugs those are missed in the I testing phase are taken care of dering this phase - If the deployed. Sepstem is modified for the 2 new Code, then the existing system should be modified on - The performance of the system is also I monitered during this phase -) new features are added to the software as Castomes reeds more features =) Maintenance phase ensures whether the customes is satisfied with the product tha has been delivered Deliverables cepdated version of the produe Code maintainance Live System
