The document discusses the system development life cycle (SDLC), which is a conceptual model used in project management that describes the stages involved in developing an information system. It is a multistep, iterative process that provides a structured framework for technical and non-technical activities to deliver a quality system. The SDLC gives structure and defines the phases and steps involved in developing a system, and serves as a foundation for project planning, scheduling, and estimating. It also assists in lowering project risk and increasing visibility. The SDLC framework includes activities such as requirements gathering, design, implementation, testing, and maintenance.

2 System development life cycle has six stages of creating a system. 3 Each step is important as it plays a significant role in a project. The development cycle involves the developing and implementing systems in order to retire the information systems from initiating, analyzing, designing the systems to the implementation and maintenance phases. The process is best used when creating or updating a database system and is most useful when undertaking a large project.
· Planning- Stage where you outline the problem, the main objectives, and all resources which will be required for use. 4 After that, you choose if you will create a new system, make some upgrades to the existing system or just leave the current system as it is.
· System Analysis- Determination of the client’s needs. The client is tangled as they clarify how they need the development to be carried out and in what way it will ensemble their needs. 4 Thus, documents the necessities and gets a sign-off from both the customer and administration to go forward with the system.
· System Design- It is the architectural phase. The members derive the logical plan and construction of flow of information for the system. Concrete coding is not yet underway at this period.
· System Implementation- We begin the actual coding of the system begin. Developing and installing of the system begins here. Maintenance, as well as any other future updates of the system, are carried out in this phase.
4 · System testing and Integration- After coding is comprehensive, the system goes over a severe test to see if it has any excuses and that it is steady. Once it concludes the assessments, the consumer can now use it.
· System maintenance- If a consumer has any inquiry or apprehensions about the system, they can get sustenance from the designers who remain to maintain the system. Operations such as backups and recovery can be performed in this stage as well as issuing of permissions by the system’s administrator.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

UNIT-III SYSTEM DEVELOPMENT LIFE CYCLE.pptx
1.
2. Conceptual model used in project management that describes the stages
involved in an information system development project, from an initial feasibility
study through maintenance of the completed application.
Multistep, iterative process, structured in a methodical way.
SDLC is used to model or provide a framework for technical and non-technical
activities to deliver a quality system which meets or exceeds a businesses
expectations or manage decision-making progression.
Every hardware or software system will go through a development process which
can be thought as an iterative process with multiple steps.
SDLC is used to give a rigid structure and framework to define the phases and
steps involved in the development of a system
3. It serves as a foundation for project planning, scheduling, and estimating.
It is a mechanism for Project Tracking and Control Method.
Increased and accelerated development speed
Assists you in lowering project risk and project management plan overhead.
Provides a framework for a consistent set of activities and deliverables.
Increases the visibility of project planning to all development partners,
Stakeholders etc.
Improved and Enhanced client relationships
4. Having a clear view of an entire
project, workers involved,
estimated costs and timelines.
Gives project managers a
projected base cost of the project.
Goals and standards are clearly
defined.
Developers can move back a step
if something does not go as
expected.
Due to assumptions made at the
beginning of a project, if an unexpected
circumstance complicates the
development of a system, then it may
stockpile into more complications down
the road. As an example, if newly
installed hardware does not work
correctly, then it may increase the time
a system is in development, increasing
the cost.
Some methods are not flexible.
It can be complicated to estimate the
overall cost at the beginning of a
project.
Testing at the end of development may
slow down some development teams.
5. • With the SDLC one can clearly see the goals and the problems so that the plan is
implemented with precision and relevance.
Clarity of the Problem Statement and Goal:
• Project members cannot move from one stage to another until the prior stage is
completed and signed off on by the project manager. A formal review is created at the
end of each stage, which allows the project manager to have maximum management
control.
Project is designed with clarity:
• The installation in a project that is executed using an SDLC has the necessary checks
and balances so that it will be tested with precision before entering the installation
stage.
Project is properly tested before being installed:
• The SDLC gives you a well-structured and well-documented paper trail of the entire
project that is complete with records of everything that occurs.
If key project member leaves, a new member can pick where old left
6. • If paperwork is missing or incomplete, the new project member will have to start from
the beginning and even possibly change the project to make sense of it.
Without the SDLC, the loss of a project member can set you back and potentially ruin
the project.
• Sticking to a budget is easier with a well-organized plan with all the timetables and
costs. Project members can submit their work to an integrated system that flags
anything that is past due. When the project manager can spend less time
micromanaging, he or she can spend more time improving efficiency and production.
The project manager can properly manage a project if deliverables are completed on
time and within the budget.
• The stages are meant to feed back into the earlier stages, so the SDLC model provides
the project with flexibility.
The project can continuously loop around until it is perfect.
• It's the best way to ensure optimal control, minimize problems, and allow the project
manager to run production without having to micromanage the project members.
When designing and implementing a project, a software development life cycle is the
solution.
7. Systems Analysis
• Process of collecting and interpreting facts,
identifying the problems, and decomposition
of a system into its components.
• Conducted for the purpose of studying a
system or its parts in order to identify its
objectives.
• It is a problem solving technique that
improves the system and ensures that all the
components of the system work efficiently to
accomplish their purpose.
• Analysis specifies what the system should
do.
Systems Design
• Process of planning a new business system
or replacing an existing system by defining its
components or modules to satisfy the specific
requirements.
• Before planning, you need to understand the
old system thoroughly and determine how
computers can best be used in order to
operate efficiently.
• System Design focuses on how to
accomplish the objective of the system.
System Analysis and Design (SAD) mainly focuses on
Systems
Processes
Technology
8. Planning Stage
Feasibility or Requirements Analysis Stage
Design and Prototyping Stage
Software Development Stage
Software Testing Stage
Implementation and Integration
Operations and Maintenance Stage
9.
10. Defines the problem and scope of existing system.
Overview the new system and determine its objectives.
Confirm project feasibility and produce the project Schedule.
Threats, constraints, integration and security of system are considered.
A feasibility report for the entire project is created at the end of this phase..
11. Requirements Determination
A requirement is a vital feature of a new system which may include processing or capturing of data,
controlling the activities of business, producing information and supporting the management.
Requirements determination involves studying the existing system and gathering details to find out
what are the requirements, how it works, and where improvements should be made.
Requirements Anticipation
• It predicts the characteristics
of system based on previous
experience which include
certain problems or features
and requirements for a new
system.
• It can lead to analysis of
areas that would otherwise
go unnoticed by
inexperienced analyst. But if
shortcuts are taken and bias
is introduced in conducting
the investigation, then
requirement Anticipation can
be half-baked.
Requirements Investigation
• It is studying the current
system and documenting its
features for further analysis.
• It is at the heart of system
analysis where analyst
documenting and describing
system features using fact-
finding techniques,
prototyping, and computer
assisted tools.
Requirements Specifications
• It includes the analysis of
data which determine the
requirement specification,
description of features for
new system, and specifying
what information
requirements will be
provided.
• It includes analysis of factual
data, identification of
essential requirements, and
selection of Requirement-
fulfillment strategies.
12. Interview
• Systems analyst collects information from
individuals or groups by interviewing. The
analyst can be formal, legalistic, play politics,
or be informal; as the success of an interview
depends on the skill of analyst as interviewer.
• It can be done in two ways −
• Unstructured Interview − The system
analyst conducts question-answer session to
acquire basic information of the system.
• Structured Interview − It has standard
questions which user need to respond in
either close (objective) or open (descriptive)
format.
Advantages of Interviewing
• This method is frequently the best source of
gathering qualitative information.
• It is useful for them, who do not communicate
effectively in writing or who may not have the
time to complete questionnaire.
• Information can easily be validated and cross
checked immediately.
• It can handle the complex subjects.
• It is easy to discover key problem by seeking
opinions.
• It bridges the gaps in the areas of
misunderstandings and minimizes future
problems.
13. Questionnaires
• This method is used by analyst to gather
information about various issues of system
from large number of persons.
• There are two types of questionnaires −
• Open-ended Questionnaires − It consists
of questions that can be easily and correctly
interpreted. They can explore a problem
and lead to a specific direction of answer.
• Closed-ended Questionnaires − It
consists of questions that are used when
the systems analyst effectively lists all
possible responses, which are mutually
exclusive.
Advantages of Wuestionnaires
• Effective in surveying interests, attitudes,
feelings, and beliefs of users which are not
co-located.
• Useful in situation to know what proportion of
a given group approves or disapproves of a
particular feature of the proposed system.
• Useful to determine the overall opinion before
giving any specific direction to the system
project.
• Reliable and provides high confidentiality of
honest responses.
• Appropriate for electing factual information
and for statistical data collection which can
be emailed and sent by post.
14. Description
• Review of existing records, procedures, and
forms helps to seek insight into a system
which describes the current system
capabilities, its operations, or activities.
Advantages
• Helps user to gain some knowledge about
the organization or operations by themselves
before they impose upon others.
• Helps in documenting current operations
within short span of time as the procedure
manuals and forms describe the format and
functions of present system.
• Provides a clear understanding about the
transactions that are handled in the
organization, identifying input for processing,
and evaluating performance.
• Helps an analyst to understand the system in
terms of the operations that must be
supported.
• Describes the problem, its affected parts, and
the proposed solution.
15. Description
• This is a method of gathering
information by noticing and observing
the people, events, and objects. The
analyst visits the organization to
observe the working of current system
and understands the requirements of
the system.
Advantages
• It is a direct method for gleaning
information.
• It is useful in situation where
authenticity of data collected is in
question or when complexity of certain
aspects of system prevents clear
explanation by end-users.
• It produces more accurate and reliable
data.
