When we talk about methodology, we mean that it has always been involved in every single project. This is because a project without planning and strategy will likely lose direction and lack analysis. Methodology, solves exactly the problems indicated above. As it provides a clear schedule and every step involved in a project. Coming to the Lotuskrish, we will compare some methodologies and discuss to identify the most suitable methodology to use in this project. Therefore, the comparison and advantages will be clearly expressed below and I take SPIRAL, PROTOTYPE and SSADM as a suggestion. Comparison Methodology Spiral Prototype SSADMAdvantages-Risk avoidance-Software is produced at the beginning of the software life cycle-Features can be added additions on at an advanced stage - Users are actively involved in development - Users gain a better understanding of the system - Errors can be detected at an early stage - Missing features can be identified - Structured and robust documentation - Better quality - Effective use of skills - Better timeline Disadvantages - Risk analysis requires specific skills - Not suitable for both small and large projects - May be an expensive model - May increase project or system complexity and may be spent beyond the original system-Leads to implementation - Over-analysis- This methodology does not support going back to the previous phase- It could be costly if something goes wrong in the middle of the advanced phase. Each methodology has pros and cons, therefore we must compare various methodologies and select one of the best and suitable for the particular project. Based on the information we gathered from Lotuskrish and arrived at a methodology to use in the project. JustifyFirst of all, the reason why I choose these methodologies is because the information we have collected from Lotuskrish is suitable and meets the needs requirement of the methodology. Three of these are capable of working properly and effectively with larger projects. Next I will briefly discuss why among three methodologies. SpiralSpiral is an iterative methodology, the spiral model has four phases such as planning, risk analysis, development and testing. The project will go through four phases and repeatedly until the project is completed. SuitabilitySpiral is a very useful model for working with the project when it comes to risk analysis, because it tends to focus on the risk of the project. Therefore, I chose the spiral because the company has just started to computerize its system and currently still uses an old and strategic system. This means that any changes to the organizational structure could affect the project or system.
