Phased Approach Advantages And Disadvantages

The implementation process of new software into an organisation is a complex process that considerable planning and analysis due to the amount of influencing factors that can impact the success of failure of the software (Seethamraju, 2014). The implementation of a new system is considered an important innovation that aims to improve current processes and organisation workflow which often encompasses all departments of the organisation to discuss the project planning, resource allocation, timelines and ensure concerns are raised with an appropriate action plan (Frimpon, 2012). This paper will discuss the different types of phased implementations and compare these strategies to the advantages and disadvantages of the big bang approach. Furthermore, …show more content…
The length of time that phased implementations can be implemented can be considered an expensive disadvantage however, time is advantageous to the organisation as it allows adequate time for staff to receive training as policies and procedures are incrementally applied as opposed to learning these all at once (Hunt et al., 2013). The phased implementation also allows processes and functionality errors to be amended and analysed before the software is introduced to the organisation reducing the risks involved and building trust within users that new system will function more efficiently then previous systems (Highfield et al., 2011). Additionally, in parallel implementation strategies due to both old and new systems running simultaneously, should any issue interrupt the functionality, organisations are easily able to revert back to previous processes without impacting patient care (Khanna, 2012). The disadvantages of phased implementations include the length of time and continuous changes required to implement the system, which can often be disruptive to users, this also allows users to compare old and new systems or adapt customisation strategies, which may not have been predicted by the project team (Khanna, 2012). Furthermore, the parallel implementation has more disadvantages due to the inefficient duplication of work, effecting productivity of staff and risks associated with human and …show more content…
The implementation also prevents the confusion among staff as clear timeframes are defined prior to the implementation as the organisation as a whole adopts the new system at the same time, preventing prolonged staff frustrations and reduced training content as staff are only required to learn one new system as opposed to a gradually changing system (Suganthalakshmi & Muthuvelautham, 2011). The disadvantages of big bang implementation include financial hindrances due to the costs associated with training and support, as all users are required to be trained which can be timely and difficult to conduct depending on space available in organisations and more extensive support is required for end users for periods of time after the big bang execution has been implemented (Hunt et al., 2013). Furthermore, organisations will experience a reduction in productivity and increase in user errors due to the changes in workflow processes however, if the system is flawed staff may begin rebelling against the adoption of the software causing multiple process and documentation errors (Denning, 2014). The big bang implementation is also considered high risk due to the potential of the software functionality to be flawed as often small issues
