SAP

System, Application &

Products in Data Processing
SAP is a software used by many businesses as it has
become famous in the current business scenario. SAP
Software's popularity has increased since 2019 as it is
different from other ERP systems. SAP offers benefits in
the technology-driven world to transform businesses
and provide solutions.

The full form of "SAP" is “Systems Applications and

Products in Data Processing” which is a type of ERP
system. Originally, SAP was known as systems analysis
program development
What is ERP?
The full form of ERP is Enterprise Resource Planning, so as
the name defines it works to integrate many procedures into a
single system. ERP combines finance, supply chain,
procurement, manufacturing, HR, service for creating
business-related planning.

In the current era, ERP systems are essential to handle

business-related work. Business owners can use ERP software
to automate business-related activities. The business holds
many activities like procurement, risk management, CRM,
project management, etc.
Founders of SAP
On April 1, 1972, five former IBM employees –
Dietmar Hopp, Hasso Plattner, Claus Wellenreuther,
Klaus Tschira, and Hans-Werner Hector –started the
company SystemAnalyse
Programmentwicklung(System Analysis and Program
Development), with a vision of creating a standard
application software for real-time business
processing. SAP stands for Systems Applications and
Products in Data Processing.
SAP - Business Model
•SAP has a mass market business model, with little
differentiation between customers. Its customers
are any enterprises that wants software for the
purpose of managing operations and employees.
The SAP business model entails designing and
developing new software products.
•SAP has a value-driven structure, that aims to
provide a premium proposition by adding its
products with training and consulting services. Its
biggest cost driver is sales/marketing expenses, a
fixed cost.

•Co = Controlling
•MM = Material Management
•SD = Sale & Distribution
•HR = Human Resource
•PP = Production Planning

SAP History and
Evaluation
•1972 – SAP started Financial Accounting Software

•1973 - SAP R/1 was the first version, and it is one tier
architecture in which three layers Presentation,
Application, and Database are installed in one
system/server
•Server one – Presentation + Application + Database
•1979- SAP R/2 is the mainframe version of the
software, and it is 2 tier architecture in which three
layers Presentation, Application, and Database are
installed in two separate servers..
• Server one – Presentation, Server two – Application +
Database
•1992- SAP R/3 is the client/server version of the
software, and it is 3 tier architecture in which
three layers Presentation, Application, and
database are installed in three server/system.
•Server one – Presentation, Server Two –
Application, server Three – Database.
 Three tier architecture –

1) Presentation Layer- Software components specialize in

interacting with end user and known as Client layer. In
SAP user interaction purpose we use GUI

2) Application Layer-Software components that specialize

in processing business applications and known as basic
layer where all programs are executed and act as
communicator between presentation and database layer.
3) Database layer- Software components that specialize
in storage and retrieval of data like fast and large hard
drives.
•2004-To meet the customers demand of better
integration between their business applications
and web, SAP developed new application called as
SAPNetweaver so all the applications of business
can run on the common platform and customers
can build and integrate existing applications easily
using SOA (Service oriented architecture). Now the
name R/3 replaced by SAP ERP and it is part of
larger family known as SAP Business suite which
also includes many other line of business (LOB)
SAP CRM.
•2015- Huge memory and multi core processors
arrive to offer massive computing power and the
existing SAP application does not fully utilize the
power of new hardware so the rewrite of complete
business suite required and new business suite is
called SAP S4HANA.
ASAP methodology
ASAP Methodology (Accelerated SAP) is a standard SAP related project
preparation and systems implementation method, developed and
updated by consultants that are involved in implementing SAP software
products. This methodology is also useful for project managers and
others who implement systems that support business processes.
The purpose of ASAP is to help project management design SAP
implementation in the most efficient manner possible, by effectively
optimizing time, people, quality, and other resources. Using the ASAP
methodology, project management provides the roadmap for optimizing
and continuous implementation of SAP systems in business processes.
This solution was developed to guarantee a successful, cost-effective
and on-time delivery of all project solutions. Developed by SAP (System
Applications and Products) in order to optimize business suites, this
framework streamlines the use of methods, tools, accelerators, and
templates that were originally developed for SAP projects.
ASAP Methodology Framework

•The Accelerated SAP methodology framework

consists of five phases of implementation; each
phase of the roadmap provides detailed plans
to assist in documentation, recommendations,
and implementation of SAP systems. Each
phase of the process ends with a quality check
that helps monitor the deliverables and other
factors of critical success. Below is a brief
description of each phase of the ASAP
methodology roadmap
Phase 1: Project Preparation
This phase focuses on the initial planning and
preparation to set ASAP goals. The phase
typically follows these three steps:

Clarify scope of implementation

Establish the team — committees, teams (core,
project and consulting)
Define the sequence of project implementation
Phase 2: Business Blueprint
The aim of this phase is to arrive at a common
understanding concerned with the procedures
intended to support the project. The Business
Blueprint is a detailed document containing all
requirements derived during initial
brainstorming and initiation meetings. This is
also where the project team revises its
objectives and goals while setting a schedule
for each.
Phase 3: Realization
This phase builds on Phase 2; it’s focused on
implementing all business process requirements.
In this phase, project managers should attain
signoff from stakeholders. Two work packages
define the system configuration methodology:

Baseline, concerned with the major scope.

Final Configuration, concerned with the
remaining scope.
Phase 4: Final Preparation
The final preparation involves testing, system
management, cut over activities, end-user training,
and all other tasks that are required to go live.
Successful completion of Final Preparation ensures
that the organization is ready to begin using the new
system.
Phase 5: Go Live and Support
This phase is the journey from a pre-production
environment to a live project operation. The
most critical elements in this phase are related
to production support setup, monitoring system
transactions, and optimizing system
performance.
