Virtually every person in the organization is involved, whether they are part of the SAP technical support organization (TSO) or the actual end-users of the SAP software. The resulting changes that the implementation of SAP generates are intended to reach high level goals, such as improved communication

Project preparation

The project preparation phase, depicted below, focuses at two main activities, i.e. to make a setup for the TSO and to define a solution

 that is charged with addressing, designing, implementing and supporting the SAP solution. This can be programmers, project management, database administrators, test teams, etc. At this point, the focus should be at staffing the key positions of the TSO, e.g. the high-level project team and SAP professionals like the senior database administrator
Database administrator
A database administrator is a person responsible for the design, implementation, maintenance and repair of an organization's database. They are also known by the titles Database Coordinator or Database Programmer, and is closely related to the Database Analyst, Database Modeller, Programmer...

 and the solution architect. Next to that, this is the time to make decisions about choosing for internal staff members or external consultants.

The image at the right shows a typical TSO chart.

Craft solution vision

The second project preparation job is to define a so-called solution vision, i.e. a vision of the future-state of the SAP solution, where it is important to address both business and financial requirements (budgets). The main focus within the vision should be on the company
Company

 process. The phase is illustrated below.

Perform cost of ownership analysis

This phase starts with performing a total cost of ownership analysis (TCO analysis) to determine how to get the best business solution at the lowest costs. This means to compare SAP solution stack options and alternatives and then determine what costs each part of the stack will bring and when these costs will be incurred. Parts of the stack are for example the hardware

 costs. Instead of performing a complete TCO analysis for various solution stack alternatives that would like to compare, it can be wise just to do a so-called delta analysis, where only the differences between solutions (stacks) are identified and analyzed. The image at the right depicts the essence of a delta analysis.

Identify high availability and disaster recovery requirements

The next step is identifying the high availability

 of the SAP system, caused by e.g. hardware failures, application failures or power outages. It should be noted that it is very important to calculate the cost of downtime, so that an organization has a good idea of its actual availability requirements.

Engage SAP solution stack vendors

A true sizing process is to engage the SAP solution stack

 and software technology partners for all layers and components of the solution stack, based on a side-by-side sizing comparison. The most important factors that are of influence here are the estimated numbers of (concurrent) users and batch sizes. A wise thing to do is to involve SAP AG itself to let them create a sizing proposal stating the advised solution stack, before moving to SAP’s technology partners/SAP vendors, like Accenture
Accenture
Accenture plc is a global management consulting, technology services and outsourcing company headquartered in Dublin, Republic of Ireland. It is the largest consulting firm in the world and is a Fortune Global 500 company. As of September 2011, the company had more than 236,000 employees across...

Staff TSO

The TSO (Technical Support Organisation) is the most important resource for an organization that is implementing SAP, so staffing the TSO is a vital job which can consume a lot of time. In a previous phase, the organization

Training

One of the most vital stages of the implementation process is training

. Very few people within an organization are SAP experts or even have worked with SAP software. It is therefore very important to train the end users but especially the SAP TSO: the people who design and implement the solution. Many people within the TSO need all kinds of training. Some examples of these positions:
  • SAP Network Specialists
  • SAP Database
    Database

. With this matrix, a manager can identify who possesses what knowledge, to manage and plan training, by defining the height of expertise with a number between e.g. 1 and 4 for each skill for each employee.

Setup SAP data center

The next step is to set up the SAP data center

, i.e. all of the technology layers and components (SAP software products) in a productive SAP installation. The most important factor when designing the data center is availability
Availability
In telecommunications and reliability theory, the term availability has the following meanings:* The degree to which a system, subsystem, or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at an unknown, i.e., a random, time...

. The high availability and disaster recovery requirements which should have been defined earlier, give a good idea of the required data center requirements to host the SAP software. Data center requirements can be a:
  • Physical requirement like power requirements
  • Rack requirement
  • Network infrastructure requirement or
  • Requirement to the network server.


Perform installations

The following step is to install
Installation (computer programs)
Installation of a program is the act of putting the program onto a computer system so that it can be executed....

 the required SAP software parts which are called components and technological foundations like a web application server or enterprise portals, to a state ready for business process configuration. The most vital sub steps are to prepare your OS, prepare the database server and then start installing SAP software. Here it is very important to use installation guides, which are published for each SAP component or technology solution by SAP AG. Examples of SAP components are:
  • R/3 Enterprise — Transaction Processing
  • mySAP BI — Business Information Warehouse
  • mySAP CRM — Customer Relationship Management

  • mySAP SEM — Strategic Enterprise Management
  • mySAP SRM — Supplier Relationship Management
  • mySAP HCM — Human Capital Management


Round out support for SAP

Before moving into the functional development phase, the organization should identify and staff the remaining TSO roles, e.g. roles that relate to helpdesk work and other such support providing work.

Functional development

SAP systems and operations management

Next thing is to create a foundation for the SAP systems management and SAP computer operations, by creating a SAP operations manual and by evaluating SAP management applications. The manual is a collection of current state system documentation, day-to-day and other regularly scheduled operations tasks, various installation and operations checklists and how-to process documents.

Functional, integration and regression testing

Testing is very important before going live with any system. Before going live with a SAP system, it is vital to do many different kinds of testing, since there is often a large, complex infrastructure of hardware and software involved. Both requirements as well as quality parameters are to be tested. Important types of testing are:
  • Functional testing: to test using functional use cases, i.e. a set of conditions or variables under which a tester will determine if a certain business process works
  • Integration testing

    Integration testing is the phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before validation testing...

Final preparation

Prepare for cutover

The final phase before going live with SAP is often referred to as the cutover phase, which is the process of transitioning from one system to a new one. The organization

  • Lock down the system, i.e. do not make any more changes to the SAP system

Go live

All of the previously described phases all lead towards this final moment: the go-live. Go-live means to turn on the SAP system for the end-users and to obtain feedback on the solution and to monitor the solution. It is also the moment where product software adoption comes into play. More information on this topic:

, there are several things that are of great importance:

1) Choose the correct SAP Consultants to have the correct blueprint.
An SAP Consultant is a professional who has the skills to speak to the managers of a company and help them creating the blueprint. For this the SAP Consultant has the business skills of the business area he/she is working with, and also masters this area on SAP. For example, if this is SAP FI (accountancy) Consultant, this person is an expert on accountancy and payments, gained through experience or by the corresponding studies at the University. Also this person knows SAP FI because has gained by the corresponding training, or the course on the SAP Partner Academy or similar.
Benefits: As this person knows about Accountancy he or she will understand the needs of the business and will bring it into reality.

2) SAP R/3 implementation is not an IT project, in fact is an Organization Project impacting all levels of a company. So it is very important to get the support from all the people that are involved in implementing SAP, but more important the participation and commitment of all levels, specially managers, of the company.

3) The Blueprint is the keystone used as the lighthouse who must guide the whole project. A blueprint should never be a merely mapping of IT systems. In fact a blueprint is bringing the strategy of a company into execution through defining its processes across all business areas. Many projects have failed because the focus was on having people with SAP knowledge, but with no business skills and so defining something that works...wrongly. Just remember, processes must change across time, and a manual error automated could be repeated infinitely.

4) Always consider changing the way things have been done before implementing SAP. "This has always been done like this and the Consultant should replicate it on SAP" is the start of a big problem. SAP many times could save you time and money as it allows your organization to automate many processes.

5) Test the SAP hardware and software rigorously by testing your business processes, and to ensure that the end-users are ready to use SAP before going live, because there are many known projects that failed because of a lack of support and SAP knowledge.

6) Design and execute a Change Management Program by communicating as early as needed all the information that end users should have to accept the new technology and designing and executing a training plan in order to reassure a knowledge base within the organizations.
