Читать книгу IT Architecture from A to Z: Theoretical basis. First Edition - Vadim Aldzhanov - Страница 51

An important element in IT management within a software development project is to estimate the time required for product development. This issue is relevant in the solution development by both: internal resources and outsourcing. A classic example is shown in the diagram.

All this can lead to such grave consequences as disruption of the project deadline, excess of the project cost (overtime, etc.) or customer’s dissatisfaction with the product quality. To eliminate above-mentioned problems, you can use the following methods and techniques:

• Poker Estimate;

• Comparison with analog;

• Bottom up & Top down;

• Expert review.

Diagram: Project cost

After analyzing one of the methods, add the following to the project timeline:

• 15—20% percent of time to cover risks and unforeseen cases;

• consider 80% percent of the developer’s work time (instead of formal 100%), as the main working unit involved in the project when making calculations.
