	8	+==== DETERMINE THE GOALS====
	9	+
	10	+* What are the high-level goals of the evaluation?
	11	+* Who wants it and why?
	12	+* The goals influence the approach used for the study.
	13	+
	14	+
	15	+==== EXPLORE THE QUESTIONS====
	16	+
	17	+Define (sub)goals & (sub)research questions.
	18	+
	19	+
	20	+==== CHOOSE EVALUATION APPROACH & METHODS====
	21	+
	22	+The evaluation approach influences the methods used, and in turn,
	23	+how data is collected, analyzed and presented
	24	+
	25	+
	26	+==== IDENTIFY PRACTICAL ISSUES====
	27	+
	28	+For example:
	29	+* Select users.
	30	+* Stay on budget.
	31	+* Stay on schedule.
	32	+* Find participants.
	33	+* Select equipment.
	34	+Perform a pilot (trial) study!
	35	+
	36	+
	37	+==== DECIDE ABOUT ETHICAL ISSUES====
	38	+
	39	+
	40	+
	41	+==== EVALUATE, ANALYZE, INTERPRET AND PRESENT THE DATA====
	42	+
	43	+
	44	+The approach and methods used influence how data
	45	+is evaluated, analyzed, interpreted and presented.
	46	+
	47	+
	48	+=== IMPACT framework===
	49	+* Intention: Clarify objectives and hypotheses/claims
	50	+* Metrics & measures: What, how and why
	51	+* People: Target group & participants
	52	+* Activities: Derive activities from use cases
	53	+* Context: Social, ethical, physical, etc. aspects
	54	+* Technologies: Hardware and software
	55	+
	56	+
	57	+
	58	+==== Formative evaluation====
	59	+Focuses on the various processes of the human-technology interaction.
	60	+Derive open questions from your design specification.
	61	+==== Summative evaluation====
	62	+Focuses on the overall effects of the human-technology interaction.
	63	+
	64	+
	65	+==== Qualitative Data====
	66	+• Words
	67	+• Drawings
	68	+
	69	+==== Quantitative====
	70	+• Numbers
	71	+• Statistics
	72	+
	73	+== GOOD EVALUATION ==
	74	+
	75	+* Establishing convincing arguments for your design solution
	76	+
	77	+* By conducting complementary and regular evaluations at different stages
	78	+of your design process using the appropriate evaluation methods
	79	+(e.g. summative, formative, expert-based, observational, ...)
	80	+
	81	+* Evaluations should result in insights regarding possible problems and
	82	+their causes in order to support refinement of your design specification
	83	+
	84	+* Look at user experience in its full breadth: Effectiveness, efficiency,
	85	+satisfaction, learnability, mood, connectedness, ...
