Phased adoption

Phased adoption is a strategy of implementing an innovation (ie, information systems , new technologies, processes, etc.) in an organization in a phased way, so that different parts of the organization are implemented in different subsequent slots. Phased implementation, phased strategy, phased introduction, phased introduction, phased introduction and staged conversion.

Overview

Information Technology has revolutionized the way of working in organizations (Eason, 1988). With the introduction of high-tech Enterprise Resource Planning Systems (ERP), Content Management Systems (CMS), Customer and Supplier Relationship Management Systems (CRM and SRM), came the task of implementing these systems in the organizations. . The following entry will be discussed at the end of this section.

The phased approach takes the conversion one step at a time. The implementation requires a thoroughly thought out scenario for starting the new system. And at every milestone one has to instruct the employees and other users. The old system is taken over by the new system in predefined steps until it is totally abounded. The actual installation of the new system will be done in several ways, per module or per product and several instances can be carried out. This may be done by introducing some of the functionalities of the system before the rest by introducing some functionalities to certain users before introducing them to all the users. This gives the users the time to cope with the changes caused by the system.

It is common to organize an implementation team that moves from department to department. By moving, the team learns and so gains expertise and knowledge, so that each subsequent implementation will be a lot faster than the first one.

The Process Data Diagram

The visualising technique used in this entry is a technique developed by the O & I group of the University of Utrecht (Weerd, 2005). The technique is described in the following Wiki: Meta-modeling technique .

As can be seen in Figure 1, phased adoption has a loop in it. Everything you need to know about the process. First ITIL, ITIL, ITIL, ITIL, ITIL, ITIL, ITIL, ITIL . Then the document and policies are documented. All processes and procedures are described in process descriptions, can be in paper or on the intranet. Then the actual conversion is depicted. As described in the above text, certain departments or parts of an organization may be implemented in different time slots. In Figure 1 this is depicted by implementing an additional module or even a total product. HRM needs different modules of an ERP system than Finance (module) or Finance. Tuning of the system to solve existing problems. After the certain department has been conversed the loop starts over, and another department or user group may be conversed. If all of the departments or organizations are conversing and the system is totally implemented the system may be dissolved.

Phased adoption makes it possible to introduce modules that are ready whilst programming the other future modules. This is the most important implementation of the project. Project Management techniques can be adopted to tackle these problems. See the techniques section below.

However, the actual adoption of the system by the users can be more problematic. The system may work just fine but it is worthless. (Eason, 1988). In this study, As this creates an extra weight on the first interaction, the implementers should be concerned with making the first interaction especially a pleasant one.

In the technique used in this entry each. All CONCEPT names in the text are with capital characters. In Table 1 the concept definition is presented.

Concept Definition
Management Decision Report The description of the selection of the process carried out before the actual implementation of the new system is described here. Decisions and requirements are described in the report too. (Eason, 1988)
Critical Implementation factors Factors that are important in the implementation process. (Umble, 2003)
Hardware specifications The configuration and specification of the hardware in place used by the legacy system and to run the new system.
Hardware test report The results of the tested hardware in place.
Software specification The configuration and specification of the software in place, ie, the legacy system and the future new system.
Software test report Software tests examines the complete software system. ( ISO 9000 )
User training log (Eason, 1988), and the “
Pilot Exercise report The report of the pilot exercise carried out with the newly installed system in a controlled single environment.
Test result Tests results of the users knowledge of the system. Real users bashing on a prototype long enoughGet thoroughly acquainted with it, with careful monitoring and follow-up of the results. ( The American Heritage Dictionary of the English Language , Fourth Edition, 2000)
Business case findings The project team creates a skeletal business case test environment which takes the business processes from the beginning, when a customer order is shipped. The findings concerned with this test are logged and reported. (Umble, 2003)
Security level report Once the training phase is finished, the setting of the security and permissions levels are necessary to ensure that everyone has access to the information they need. (Cazemier, JA, Overbeek, PL, Peters, LM, 2000)
Documentation The organization of records that describe the structure, purpose, operation, maintenance and requirements of a computer program, operating system, or hardware device. (The American Heritage Dictionary of the English Language, Fourth Edition, 2000)
Conversion scenario The redefined implementation script, taking into account the conformity to the requirements. Moreover, the conversion scenario consists of a workaround and rollback plan. The conversion scenario is the blueprint of the implementation project. (Rooijmans, 2003)
Module Implementation Plan A plan concerning the implementation of a specific module in the system of the organization’s processes is described here.(The American Heritage Dictionary of the English Language, Fourth Edition, 2000)
Product Implementation Plan A plan concerning the implementation of a specific product of the system in the processes of the organization is described here.(The American Heritage Dictionary of the English Language, Fourth Edition, 2000)
Tuning report During the implementation the implementers might want to change the system due to findings in the implementation increments.
System Acceptation The system gets accepted by the organization. (Umble, 2003)
Catch-up An approach or strategy intended to overcome a disadvantage or lead(The American Heritage Dictionary of the English Language, Fourth Edition, 2000)

Advantages, disadvantages and risks of Phased Adoption

The Phased adoption method has some pros, cons and risks (Koop, R., Rooimans, R. & Theye, M. de (2003), Eason (1988)

pros:

  • The conversion will be done in parts. Time is available for adjustments
  • Negative influences that arise
  • No ‘catch-up’ period is needed.
  • Time for the users to adapt
  • Technical staff can concentrate on part of the system or some of the users.

Cons:

  • Several adjustments are needed
  • Training sessions are confusing for users as they are asked to work with the new and the old system
  • Several changes in documentation
  • The duration of the project
  • System delivery milestone is unclear
  • Correctness and completeness of the dataset
  • A ‘fall back’ to the old system is becoming more difficult every new phase.
  • The implementation may appear unclear to the employees and other users.

Risks:

  • Complexity of the implementation
  • Prone to make mistakes
  • Fall back impossible in later phases

Hardware and software installation

Figure 3: Hardware and software installation

The Following sections are supplemental to the entry about adoption (software implementation) and are specific to phased adoption:

The configuration and specification of the hardware in place used by the legacy system and the new system is delivered in the hardware specifications. The hardware configuration is tested to ensure proper functioning. This is reported in the hardware configuration report. The configuration and specification of the software in place, ie, the legacy system and the future new system is made clear to ensure proper functioning once the system is installed. The act of specifying the system that is already installed is key to the implementation. Which parts or even total systems will be taken over by the new system? All this is reported in the software installation and software test reports. The actual installation of the software of the new system is also described in the following section.

Training

Figure 4: Training Process

The system training will teach users the keystrokes and transactions required to run the system (Umble, 2003). The pilot exercises the systems and tests the users understanding of the system. The project team creates a skeletal business case test environment which takes the business processes from the beginning, when a customer order is shipped. Training for the adoption of an information system. The users have learning needs (Eason, 1988). Known learning needs are emotional guidance. Users need to make emotional steps in order to make cognitive steps. If they fear the system due to its difficult handling they may not be able to understand the cognitive steps necessary to successfully carry out the tasks.

Techniques

In the implementation field several techniques are used. A well-known method, and specifically oriented on the implementation field, is the Regatta method by Sogeti . Other techniques are the SAP Implementation Method, which is adapted to implementing SAP systems. Systems are installed in several different ways. Different organizations may have their own methods, when implementing a system, it is considered a project and thus must be handled as such. Well known theories and methods are used in the field as PRINCE2 method with all of its underlying techniques, such as a pert diagram, Gantt chart and critical path methods .

Example

The EMR implementation at the University Physicians Group (UPG) in Staten Island and Brooklyn , New York .

The University Physicians Group in New York has an electronic medical record (EMR) package. The UPG found that some vendors of the EMR package recommended a rolling out that would also be all-at-one, also called the Big Bang. But they found out that the Big Bang would have overwhelmed the physicians and staff due to the following factors:

  • Ongoing workload during the key lessons prevented them to fully pay attention.
  • Urgent need to complete some records
  • Information overload on the physicians side.
  • No time to play around with the system.
  • 100% non-smoking hotel.

Thus they thing a phased approach: ” Hence, a phased adoption to us, offered the greatest chance of success, staff adoption, and opportunity for the expected return-on-investment once the system was completely adopted. “(J. Hyman, MD)

There was also a group that was reluctant about any new systems. By introducing the system to certain early adopters (Rogers, 1995) the late majority would be able to get to know the system. As it was introduced phased through the organization. Per loop (see Figure 5, A) the UPG was introduced to the system.
