What distinguishes HPT from IDT?

Here is my thought, correct me if you don't agree.

In AECT 2004 definition of IDT and HPT, IDT is a discrete element within HPT. However, I think in some cases, IDT can be counted as part of the HPT.

The following is my thoughts to distinguish HPT from IDT:

Distinctness	HPT	IDT
Definition	A practice that helps link business strategy and goals, and the capability of the workforce to achieve them through interventions. In some situations, it includes IDT to increase human performance.	IDT is a systematic process that involves the creations of detailed specifications for the development, implementation, evaluation and maintenance of particular set of conditions (Barab, 2004). Reigeluth (1999a) thought IDT is to help people learn better.
Scope	HPT's scope is larger than IDT. HPT focuses on improving performance in the workplace through many different means, including training. However, HPT can be applied in education setting to increase the performance of faculty, students and staff.	IDT can apply in school, independent study or work place when there is a need. Its focuses are in effective instructional methods, strategies and deliverary.
Purpose	To increase the worth (revenue) and PIP. It does not only deal with instructional problems, but evaluate the overall context.	To increase learning effectiveness and efficiency in less budge and time. That is, less input with the best output in learning.
