5 Reasons Why Architecture Assessments Are utterly Crucial for Software Projects.
A meticulous architecture assessment of a software system that is developed or still to be developed helps in understanding if the team is upon the right track to realizing the customer’s vision and business solution, not isolated at the present moment but from a objector long term incline as well.
There are primarily 5 reasons why customers should carry out Architecture Assessments for their software systems. An architecture assessment helps in…
Reinforcing the situation vision and objective(of the architecture).
Realizing the current state(of the architecture).
Identifying unknown risks and addressing known problems.
Defining the long term strategic roadmap.
Realizing the ROI.
Reinforcing the objective
One of the most crucial reasons for an architecture assessment is to re-ensure that the try or the goals of the architecture matches in the same way as the customer’s vision and matter strategy. Many a time’s architectures that are created are based on latest trends and best practices nearby in the make known and don’t focus primarily on the non-functional requirements of the application. while it is unconditionally a good practice to create use of the latest trends and practices it is very important we ensure we don’t astray from the main objectives defined for the architecture.
Architecture is generally derived from the non-functional requirements and is intended to achievement in cohesion past functioning requirements in order to attain the overall matter objective. The main point toward of an architecture assessment is to ensure that we are on the right track to achieving the indigenous try of the architecture. For example: every architecture has its own trade-off models, but all architecture should point toward a clear set of (non-functional)parameters that it should prioritize. It is important to prioritize between the architecture parameters viz: Performance, scalability, maintainability, reliability, extensibility. every parameters cannot have the thesame precedence else the architecture will be more of an overhead rather than a solution. This is the common cause of failures in most architecture’s. The architect loses sight of the end product and long term goals and comes up taking into consideration something unconditionally fancy by implementing the latest principles which may be fine but may not be applicable for that specific matter instance and hence ends taking place overburdening the architecture.
During an architecture assessment phase the architect assess the prescribed architecture along as soon as the NFR requirements and determines if the architecture has the right bank account that will encourage withhold the situation requirements, enlargement and vision of the customer.
Realizing the current state
This is one of the most important reasons for having an architecture assessment. It is utterly important to complete the current give leave to enter of the architecture vis-a-vie the proposed state. Architecture assessments happen at swing era of a project lifecycle. Ideally it should happen just since the begin of design or before the begin of development. However that may not be the charge bearing in mind most software projects due to timeline crunches and project pressures. hence in most cases architecture assessments are finished reactively to give a positive response care of a particular set of problems that has risen (during development/UAT/production) rather than preventing its occurrence in the first place itself. Examples are: conduct yourself problems, maintainability problems, nonattendance of scalability etc.
In genuine world projects we have architecture assessments the end to address project complexities that are without difficulty into the build up or during UAT phase. Sometimes it’s even ended during the production phase upon request of the customer due to a dis-satisfactory proceed of the application. appropriately it is imperative to acknowledge gathering of the current architecture implementation, to understand the gap if any amongst the current architecture and the proposed architecture and to attain the current confess and explanation for the same.
80% of mature the development architecture has more than 50% of anomaly following compared later than the proposed architecture. This is mostly due to the nonexistence of without difficulty defined requirements, gap in arrangement or lack in long term vision whilst finalizing the architecture during the proposal stage. suitably it is important to understand this abnormality and the excuse for the same, its root cause that warranted it and assess if we are on the right track or not. Many a get older the deviations are warranted and at times it’s just due to timeline crunches and due to implementations of “work-arounds”. whatever maybe the skirmish it is imperative to assess the impact of the amend subsequent to adulation to the overall vision desired by the customer. This part of the assessment serves as the bases to derive the united risks and plot of function for the similar to ensure the architecture is put back up on the right track.
Identifying ordinary risks and addressing known problems
Once we have assessed the current allow in of the architecture we subsequently obsession to identify the probable risks allied when it and residence the known problems along the showing off as well. This is probably one of the most well-known reasons as to why an architecture assessment is requested in 60% of the cases. It is because the processing suspect that there could be a lot hidden risks that have developed during the implementation phase of the project or because the project has numerous bugs during the breakdown phase. regrettably an architecture assessment at this stage is ended to put in quick fixes to attain a gruff term outcome. The long term suggestions at this stage are generally very expensive to approve in the past it involves a substantial amount of re-work and therefore may be ignored as long as the application is full of life “Today”.
These suggestions are generally ignored until the application deteriorates therefore much that it becomes virtually directionless and the customer would be forced to rewrite the application. appropriately past the current confess of the application is known it is categorically important to analyze this data effectively and identify the unexceptional risks as well as prepare a rude term and long term roadmap to house the known problems. Sometimes customers and project teams are lonely keen in addressing the known problems but it is entirely important for the architect to own up the importance of a long term solution on top of a curt term fix. It becomes even more important in cases like existing confess of the architecture has deviated considerably from the proposed state. It becomes a necessity to get the architecture incite upon track even if simultaneously addressing the known pain areas as well. only after we get this we can ensure that we have not deviated from the long term issue vision of the customer.
Defining the long term strategic roadmap
This phase would not be required in cases where the implemented architecture doesn’t deviate from proposed architecture, previously even if proposing the architecture it is the adherence of the architect to create an architecture subsequent to a long term vision and customer’s business objective. This phase however is something like always required in the past the implemented architecture around always deviates from the proposed architecture for reasons mentioned above.
During this phase the architect reassess the native vision and analyses the current architecture to ascertain its deviation from the same. It is during this phase that the architect after that addresses the throbbing areas and problems and creates a detail answer for the same. He furthermore prepares a roadmap which contains corrective actions to ensure that along like addressing the known problems and mitigating the known/unknown risks he after that puts in a detail technical scheme to realign the architecture as per the indigenous design and expected standards.
Realizing the ROI
This is probably the most difficult matter to calculate as outcome of an architecture assessment but this is probably the most important upshot that an architecture assessment should generate. Customers invest in a lot of child support in architectures for that reason it becomes absolutely critical to verify they are getting value for their money invested. Many a time a lot of allowance gets invested in implementing the latest architectures in the market. As good as those architectures may be they may competently have been intended to address a stand-in set of problems. appropriately applying a general set of latest architecture principles to want a broad range of problems is not in fact giving the customer value for money.
At the stop of the architecture assessment it is categorically important to derive the value for maintenance or genuine ROI the customer has conventional from the architecture prescribed, especially if the architecture assessment is subconscious carried out broadcast increase or herald production. In instances where the assessment is carried out before loan later in those cases we would habit to calculate the projected ROI the customer would be expected to receive. Giving real numbers to our customers is the deserted mannerism to generate confidence in customers as competently as it keep us architects in check from more than prescribing fancy architectures which may not be aligning bearing in mind customer’s vision.
An architecture should be crisp, focused and extremely aligned once the customer matter requirement and should be adept to grow proportionally with the business. A fine architecture contains the perfect financial credit of highbrow components that have been expected after prioritizing the non-functional requirements of the customer.
The article outlines the 5 most important reasons why customers and spread teams should pro-actively carry out architecture assessments. In fact the cost of an architecture assessment should be budgeted for in the overall project cost. Ideally it’s fine to have it the end prior to the start of the move ahead phase. However no issue in what stage it is carried out, it nevertheless provides a lot of value by accumulation stability and reinforcing long term matter vision of the customer.
