Planning for technical design and construction is essentially the assembly and publishing of material created in the earlier tasks, with the addition of preliminary project plans. Follow a standard planning procedure. Steps are:
- Review the standard tasks -
Take note of any new or unique tasks that have to be built into the plan, and then create a planning chart. Standard tasks include:
* Physical database design
* Conversation and transaction dialog design
* Message size and interaction frequency design
* Computer resource requirements design for each interaction
* Screen layout timing and frequency design
* Report layout timing and frequency design
- Estimate design resources -
Take account of the software to be used and the skills of your available staff, as well as of application details.
- Estimate technical design time scales -
These will depend upon the estimates of design resources and on the availability of the appropriate people.
- Describe risks -
Take actions to control risks and amend the plan if necessary.

Phase Plan.
Purpose of Technical Design Phase
A technical design project prepares an implementation area for construction
and installation. The key tasks are therefore structured to produce a system
and database that meet the user's acceptance criteria and that are also
technically sound.
Objectives of Technical Design Phase
A technical design (TD) project aims to define efficient system and database structures for an implementation area. It is based on the design of a business system developed by a business system design (BSD) phase project.
The objectives of the technical design stage are to:
* Specify the data storage to support installation of the system
* Define the data structures to be used
* Define the programs, modules and computing facilities involved
* Assure that the physical data structures and computer program structures are supported by the hardware system
* Assure that the system performance meets or exceeds specification
to establish all construction and implementation requirements

Task Dependency Diagram
Tasks:
There are eleven tasks conducted during the technical design (TD) stage, each comprised of a set of subtasks. The tasks of TD include the following:
* Specify the technical objectives for the implementation area
* Specify the technical context, standards and requirements of the system
* Specify the hardware and software components
* Define the preliminary data structure into an implementable database design
* Refine and design procedures into modules and programs
* Define the implementation interfaces, procedures and user training required
* Design the operating support for security and integrity control, and performance monitoring
* Check that the system will meet performance objectives
* Specify integration, system and acceptance tests
* Define what is to be done in the construction and implementation projects
and obtains management acceptance of the plans
