Architectural Design Process
The process of designing a building, space or structure typically consists of these design phases. It is important to understand and remind yourself of these phases, to bear in mind exactly what you're trying to accomplish. And it does take time.
Solution
Remember that while the information and decisions made in one of these phases / stages forms the basis of the subsequent stages, design is seldom a linear a process. Instead, one typically moves back and forth between the phases, allowing ideas from more detailed designs to influence and modify the overall design direction previously established.

Furthermore, in practice these phases often blend into one another.
Supporting Patterns
Programming is the activity of determining the "program", or set of needs that a building needs to fulfill.

After establishing the program for a project, the focus in the architectural design process shifts from what the problems are to how to solve those problems. During schematic design, the focus is on the "scheme", or overall high-level design. Here, minor details should be ignored to instead focus on creating a coherent solution that encompasis the project as a whole.

During the design development phase of the architectural design process, the scheme is refined into the final design. In previous phases, the focus has been on the project as a whole. During Design Development, in becomes important to give individual attention to each aspect, each space and each detail of the project.

At this stage of the architectural design process, the focus shifts from design to communicating the design and providing all information necessary for construction.
