Prioritization
§ The word prioritization derives from the Latin adjective „prior“ for earlier, first.
§ Prioritization helps to allocate resources by sorting tasks, problems or other items according to their
§ importance (relevance, criticality) and/or their
§ urgency (short/middle/long term)*
§ The purpose is to usefully allocate the limited (financial) resources, capacities and time.

The Eisenhower Method

§ Well known and self-explanatory
§ But, in everyday life the urgent supersedes the important
§ When something gets urgent, it is mostly already too late
§ Often, a lot is urgent and important (thus, it isn‘t divisible or even manageable any more)
not urgent urgent

Which are the true priorities?
Page 5
Existing prioritization is often too superficial and does not really address the very (un-)critical topics.

Different Views!

Each stakeholder has his own view of „what is how important“.
Project Manager

Customer
End User
Suppliers Specialists
Management Business
Additionally: - Common understanding - Understand each others needs - All information available

Challenges
§ Current models often don‘t help in identifying the really important elements
§ 80% are priority 1 (or priority AAAAAA+++)
§ The focus is not on the really critical or profitable topics
§ Important stakeholders are often not included in the process, which results in a lot of disagreement about priorities
§ The social process of creating a mutual understanding is ignored

Prioritization
u Is a unit of measurement
u Is a middle way between subjective and objective evaluation
Priority Poker provides this middle way
Ø All project members who are important for prioritization get involved
Ø Individual first estimates followed by discussion
Ø Final decision by the team after the second estimate

Use of Relations
Page 10
Not important Extremely important
The relative evaluation reveals their importance in relation to each other.

Relative Estimates
Page 12
Working with relative estimates is often easier and more precise. They remain valid even if the assumed basis of the relation changes.
Pro‘s Con‘s § First estimates take more time,
until the team is in the „flow“
§ Reference objects are needed as a point of orientation for estimators
§ Risk of solution-oriented or other philosophical discussions during sessions
§ Risk that single estimators dominate the group or use their political power
§ Relation mostly remains the same even if the absolute value of an item changes (e.g. complexity or number of users)
§ There are no discussions about absolute values (LoC, number of users, etc.)
§ The really important elements are identified very quickly. So do the unimportant ones.
§ If an element is extremely important it can be split up for more deliberate processing

The Procedure also includes...
§ Estimate of Experts § Knowledge is at hand § Open questions can be answered § Team estimate doesn’t put too much focus on experts
§ Analogies § Comparison of / relation to other items during estimation
§ Disaggregation (maturity / dissolution) § Splitting up elements because of too high complexity, risk, etc. § Revealing and closing information gaps
§ etc.

Setting Priorities Right

Priority Poker
Page 18
When playing Priority Poker, all stakeholders set the priorities together. Be it for requirements, change requests, risks or test cases.
§ Priority Poker uses the corresponding game cards (can be ordered at SwissQ) and a list of elements to be evaluated such as requirements, specifications, user stories, use cases, test objects, test cases or bugs.
§ All relevant stakeholders participate, the selection and distribution of information has to be done beforehand. Each person receives a card set.
§ A moderator - who doesn‘t play the game himself - is leading the poker session. He is responsible for the adherence to the time boxes and suppresses solution-oriented discussions.

Rules
§ Time boxes have to be respected Each activity in Priority Poker is time boxed and the moderator has to make sure that those time boxes are followed.
§ No solution-oriented discussions Only questions about comprehension will be allowed and answered during the poker rounds. If a topic on the priority list remains unclear it has to be discussed outside the round and will be reintroduced into another poker round later.
§ No session lasts longer than two hours A new session will be scheduled if there are still non-prioritized topics on the list after two hours.

Priority Poker works because...
§ Priority Poker brings together different experts and decision makers. These experts make up a „cross-functional“ team uniting all important disciplines, and therefore constitute the best team to set the priorities.
§ The active exchange during the Priority Poker session ensures the information flow between those experts and thus leads to a common view of the priorities which is supported by all parties.
§ And it‘s fun!

Priority Poker can be used for (practically) anything!
§ Project plans and activities
§ Design of roadmaps
§ Release and product planning
§ User stories
§ Evaluation of ideas and innovation
§ Nutritional value of food...
