The software industry is well known for using both Agile and Scrum Methodologies for bringing out the end product to the market through owners. It is very much Important to know better implementation at the time of a project.
As the experts know, there isn’t a single methodology that precisely serves each of the requirements of every project. So, to decide any methodology as best-fit to the project, the circumstantial approach on how it works must be understood and evaluated.
For the purpose, let us discuss the difference between Agile and scrum methodology each, in various aspects of functioning and execution. To know more about Scrum Master Certification please visit StarAgile site.
What is Agile and Scrum in software Industry?
Agile and scrum are the kind of approach used in the software industry to get the work done productively. Agile approaches the project by cleaving the entire product into diminutive assembles, while the focus of the scrum is on reaching the end product within smaller amount of time. Scrum is one of the features of Agile. To make it clear, let us consider an everyday example. We have hot, cold and warm water. Water has some characteristics. ‘Cold’ is one of its feature. Likewise, scum is one of the agile processes.
The analogy makes it clear to understand the basic difference between agile and scrum.
If Agile is a developmental tactic formed through repetitive and phased appeal, scrum is one of execution of agile tactics.
· For the size of project.
Agile is suitable for small projects requiring experts while scrum is ideal for drastically changing requirements. If the size of the project is tiny but it needs the honed working minds for reaching the well pleased closure precisely without missing on single aspect, agile is the tailor made approach. Scrum will suit if the project has varying requisites.
· Individualistic qualities.
The individuals involving in the project play a distinguishable role for the project success. In Agile the entity participating in the project requires to be functioning well. An overall working as a team accounts to most of the fruitful outcomes. So the directorship and leadership is important. Scrum depends on individual contributions separately, so the self organizing is the way.
· Reaction to changing circumstances.
Agile is supple to the changing circumstances. This flexibility plays as a benefit in Agile.
Scrum will be unable to cope up with the changing circumstances as that of Agile. It takes time. Its stiffness to repeated changes is a downside for profitable projects. It would be better if scrum wasn’t so rigid.
· Way of building liaison.
The interaction between the various groups involving in the project is one of the appealing factors while choosing the right approach. The periodicity in exchanging of the ideas results in delivering the required amount of progress. In agile the interactions are open between the every directly or indirectly participating group. In scrum the interaction takes palace separately among the various participating teams. To be precise, the meetings are within the groups. The scrum master transfers the summary for the other participating groups and product owners.
· Representation of concerns.
When it is about communicating the hurdles, there is a head assigned to the project, in agile approach. The head represents the involving group of the project. The head transfers the hurdles faced to the suitable entity to get the guidance and expositions. In scrum, every one individually presents the concerns and hurdles to the entity. Sometimes, this could be clumsy.
· Recurring deliveries.
The beauty or the main essence of the agile team is to produce recurring deliveries. This type of approach accounts for many of the benefits to the project. The team can deliver multiple features in short span of time. This is applicable for both end users and internal teams. On the contrary, the scrum gives a final delivery to the end users by undergoing adequate discussions internally.
· Maintaining time.
Due to dividing of the project into multiple portions, the functioning is eased. This approach allows recognizing the flaws instantly, which enables the quick eminent delivery. The final outcomes are impeccable. Scrum works on entire product of a project. The may be stages, but it is confined to limit for the functional units.
· Design and execution
Due to multiple executions in Agile, the design happens to be simple. It will not take anything different or something that wasn’t done before. So is for the execution. Both are retained straightforward. Scrum unlike agile works on trying out new and ingenious. With the scrum Designs and execution, the approach yields concise and smart outcomes.
· Tracking progress
The Agile requires the detailed tracking of the progress. So, tracking takes place after every milestones of overall design. For the ease, the design is divided into multiple pieces. It is not just the design but also the process and analysis have to be monitored in periodical intervals. In case of scrum, the monitoring takes place after completion of certain functional units of the project rather than each design. Overall, the monitoring by Agile is for more divisions than scrum. Hence the scrutinizing is excess in Agile.
· Review during work progress from the end users.
Agile has practical approach to make the project productive and realistic. While the part of the work is finished, it releases the product to the end users. The users will express their reviews and concerns. The remaining part of the product will be designed to accomplish the under met or unmet aspects of previous part. This will be beneficial as the product can be extricated form a total failure. In case of scrum, only the final product is released to the end users. Adequate discussions are directed internally to ensure the success of project.
· End product delivery
As in Agile the concerns of the end users are repeatedly taken and is open for timely suggestions from any part of the involved teams, the end product may be not of the original expectations. The recurring quality of the Agile will compensate the difference. Scrum has the decided outcomes for functioning units.
Having understood the working of scrum and Agile in detail, the concerned will be able to choose the right one to use for the project by holding a brief on the overall analysis. By taking all the factors into account, the approach that is fulfilling most of the project essentials will be considered as the appropriate for that particular project.
