Any solution can be limited by various constraints and may encounter issues due to complexities or unforeseen risks. Solution architecture needs to balance multiple constraints, such as resources, technologies, cost, quality, time to market, frequently changing requirements, and so on.

Each project has its own specific goal, requirement, budget, and timeline. Solution architecture evaluates all of the possible critical paths and shares best practices to achieve a project goal in a given timeframe and budget. This is a systematic approach, where all tasks are interdependent of its prior task, and in order to achieve success in the project, all tasks need to execute in sequence. A delay in one task can impact the project timeline and can result in the organization losing the market window to launch the product.

If there is an issue in the project development process, the probability of a project getting delayed is higher. Sometimes, you encounter problems that are limitations of technology or of the solution environment. If you have a well-thought-out solution architecture, the most common issues are related to the non-functional requirements; resources and budgeting can mitigate for the product development life cycle. 

A solution architect helps to drive the project by diving deep into each component of the project. They think of an out-of-the-box idea to save the project from the issues, and they will prepare a backup plan in the event that things do not work out as in the main plan. They evaluate the best possible way to execute the project by choosing the best practice and balancing constraints.
