Components:
Central Executive: This has overall control. It has limited capacity and can process information.
Phonological Loop: Has 2 separate stores in; the phonological store and the articulatory loop. The articulatory loop is the inner voice and repeats sounds.
Visuo-spatial Sketchpad: Holds visual/spacial information.
Episodic Buffer: Store for everything.
The Episodic Buffer was added in at a later time.

Strengths and Weaknesses:
The model is very influential and psychologists use the WMM in place of 'STM' in the MSM. It is better than the MSM because it looks more at processes. It gives more than 1 way of transferring information (not just rehearsal).
A lot of research backs the model up in place of what the MSM can't explain.
It explains some individual differences. For example the processes can explain how the phonological loop is not operative in some children with dyslexia.
It is more valid than the MSM because it can be applied to real life settings. There is a high correlation between memory span and performance on certain tasks which link to specific jobs for specific people.
The role of the Central Executive isn't clear.
It doesn't account for musical memory.
