A Framework for Thinking about
Feedback and Evaluation & Learning
View 1
Learning requires feedback. In order to learn we need to know whether we are moving
towards or away from our desired goals. Feedback provides information about the gap
between where we are and where we want to be.
I’ll use the terms “feedback” and “evaluation” interchangeably with full awareness of the
entailed abuse of ordinary language. In common parlance “evaluation” has a normative
dimension. We do sometimes speak of “negative feedback.” On the surface this also
seems to entail a normative judgment. This is a misinterpretation. “Negative feedback” is
another phrase for “balancing feedback” or feedback about our position with respect to
some goal. This is the sort of feedback on which learning rests. It’s opposite, positive
feedback, is more appropriately labeled “reinforcing feedback,” the sort of information
that moves us to continue doing more of the same, regardless of the consequences. In the
sense in which I will use the term “evaluation” is information about our distance from a
particular goal. We evaluate our progress towards a desired end. When we evaluate a
particular action we are providing, from our own point of view, feedback about its
success as judged by the goals to which the action was directed.

Whether learning requires feedback – and the type of feedback it requires - depends upon
what learning is. If learning is the increasingly effective ability to achieve some goal or
solve a (type of) problem, then feedback is critical. We usually have to know what we’re
doing wrong in order to figure out how to do it right. Mistakes are an essential and
inevitable part of this sort of learning. But learning does not have to be goal-directed – at
least not directed to some sort of external actionable goal. Not all knowledge is
“actionable knowledge.” A different view of learning is that it leads to understanding
rather than goal-dependent “success.” Understanding may or may not have specific
practical consequences. It involves drawing new connections and discovering (or
creating) new relationships between aspects of our system of concepts and beliefs. In
doing so we necessarily change that web of beliefs and assumptions. We modify, adapt,
extend and build new concepts. In this case the role of feedback is not to inform us about
the gap between where we are and where we want to be. There is no “where we want to
be” previously defined to be informed about. The role of learning on this view is to create
a new and more productive understanding, something that did not previously exist.
Feedback can tell us whether our attempts are interesting, consistent, traditional, and
creative but not whether they’re approaching some antecedently recognized template.
And feedback can also play another role; it can prime the search for understanding with
new directions based upon different perspectives; it can widen the space of options we
consider and force us to view our situation or problem in different and unexpected ways.
One way in which this can happen is if feedback forces us to surface and question our
own mental models.

These two views thus reflect different approaches to learning and different roles that
feedback can play in the process. The first view is a sort of Platonic approach in which
there is a specific goal that can be known and it is the learner’s job is to discover and
reach it. Feedback functions as a sort of intellectual radar that tells the learner how close
he is to the ideal of knowledge at any given time. The game is over when the goal is
realized. The second view is a sort of Nietzschean anti-realist approach according to
which learning is an act of intellectual creation. Feedback functions as a catalyst for the
process enriching (or impoverishing) the environment in which it takes place. The two
views also reflect the distinction between single and double loop learning.1 Different
views may be more appropriate for different domains (e.g., science and business vs.
literature and art) and different purposes.
Perspective
The role of feedback is thus relative to the type of learning it is invoked to promote. But
it’s also relative to the perspective from which it’s offered. “What’s the point of
providing feeding feedback?” needs to be supplemented with “for whom?” as well as “for
what?” Feedback plays very different roles for the receiver and the provider. And the
point of offering feedback may differ significantly from the point of requesting it.2 The
two views discussed above both reflect the learner’s perspective: give me guidance or
give me ideas. Of course, there may be other motives less directly, but no less
importantly, tied to learning: emotional support, encouragement, personal validation,
establishing mutual interest, etc. For the provider the situation looks quite different. What
is he or she offering and getting out of the process? Unless there’s a clear understanding
about what the feedback is needed for it’s unlikely that it will serve the intended purpose.
The provider must have a clear understanding of the rules of the feedback game as
initiated by the requestor. This requires that the requestor have a very clear understanding
about what he or she expects to achieve through the request.
What Feedback Ought to Be
In a normal classroom setting, evaluation is a technically simple matter. It’s a 1-1
function the domain of which is the set of students in the class and the range of which is a
subset of real numbers, the grades. A grade is somehow supposed to provide information
about gap between some current state of the student and the desired goal. The question to
ask here is not “What’s wrong with this picture?” but “What’s right with it?” For many
reasons it seems, at best, pointless. More often, it’s positively counterproductive.
If we think of individuals, groups and classes as learning systems we’re forced to admit
the obvious: learning is a process that develops over time. One positive role evaluation
can play is to help the system perform more effectively. To do this it must therefore
satisfy several characteristics: it must be timely, it must be accurate, it must be complete,3
and it must be relevant (i.e., to the situation and goals). If any of these conditions fail, it
will inhibit the development of the system. This is not to say that appropriate feedback
guarantees success. It does not. It’s also not to say that inadequate feedback inevitably

results in system collapse. It doesn’t. But a healthy and sustainable system requires a
feedback mechanism that allows it to accurately situate itself within its environment in a
reasonably timely manner. Systematically delayed or distorted feedback, almost by
definition, guarantees extinction. So much for the background.
Who Gets Evaluated … By Whom .. and How?
In OTL we have three levels in our learning system: individual, group and class. Entities
at these levels (21 participants, 19 students, 2 instructors, 1 LOST, 6 LOGs) interact in a
number of very complex ways; individuals interact one-one with other individuals; team
members interact with groups and sub-groups; groups interact with other groups; and all
interact to somehow give rise to that mysterious entity the “class” or whole organization.
On the general principle that feedback is information about the environment that helps us
navigate, we can define a matrix of feedback types. You can provide feedback to your
group and to the class. Conversely, the class and your group can provide information to
you. You and your group(s) can provide feedback to other groups. Finally, each level –
individual, group, class - can do a self-evaluation of its own activities. In the jargon of
corporate America, this amounts to a sort of global and non-hierarchical 360° evaluation
of all entities (i.e., sub-systems) that comprise the system. (See the table below.)
So much for who gets evaluated by whom. A more challenging question is how the
evaluation is done. In developing an evaluation procedure I suggest we begin with what
Collins & Porras refer to as the “core ideology” of our organization. In any organization
success at the organizational level means, at least in part, success in realizing the
organization’s fundamental purpose. But we are not just any organization. Part of our
purpose is to become a learning organization. This immediately yields several other
broad parameters that guide evaluation. Learning is a process. A learning organization is
one in which the process of learning – scanning the environment, surfacing assumptions,
modifying actions – is no less important than what is ultimately produced. In a learning
organization how the organization behaves – its core values – are no less important in
evaluating its performance that what it delivers. To put this in another that eliminates the
process/product dichotomy, in a learning organization evaluating what is accomplished
must include a consideration of how it is accomplished. Process and deliverables are,
from the standpoint of evaluation, inseparable.
Second, in a learning organization entities at all levels do what they do not because they
are specifically told to do it. They make the choices they do because they believe these
decisions will help the organization realize its purpose. A hallmark of a learning
organization is the freedom it offers to individuals. Values and purpose (and perhaps a
more localized envisioned future) provide a general context in which the organization
unfolds. There is no specific blueprint for action. There is no commander in chief that
constantly monitors the situation. The purpose and envisioned future are in command.
Everything else is out of control.4 This is life in the chaordic lane. In order for this to
work, however, individuals and groups must share a common understanding of the
organization’s purpose. And every member entity’s goals and values must, in a very
general way, be consistent with those of the organization. This means that evaluation

criteria at every level – individual, group, and class – must reflect the overall purpose and
the core values that define the organization as a whole.5 If it doesn’t, sub-optimization is
inevitable, learning across the organization will suffer and, if the learning disability is
severe enough, the organization will fail.
Evaluation in OTL
To recap, if we want to develop useful evaluation mechanisms we first need to identify
the characteristics – the signposts – that indicate the direction in which we’re moving at
all three levels. For each level we need to have at least very tentative answers to three
questions:
Where are we going?
How will we know we’re there?
What sorts of things shall we look at to decide how close we are?
In the case of a learning organization these answers must involve not only what is
achieved (e.g., the quality of the deliverables) but how it is achieved (the process, “task
two”). Deliverables are a snapshot. They are static; a slice of time. Learning
organizations are not. They are entities that can adapt and grow. These dynamic qualities
are reflected as much or more in the processes of the organization than in its products.
They’re made manifest in the way people relate, the sorts of control mechanisms in place,
the degrees of freedom people have, the way the culture of the organization evolves, etc.
And all of these are most directly visible in the structure and processes of the
organization. These tell us the degree to which the purpose, values and concept of the
organization are implemented in its practice.
Practically speaking, as our basis for evaluation we will need to translate the “How will
we know we’re there?” question (now broadly understood to include process as well as
deliverable) to each level of the organization. For each cell in the table below there
should therefore be both product and process (task 1 and task 2) questions that help us
decide whether we moving towards or away from a learning organization.
Note that the discussion of evaluation in this concluding section is tied to the first role of
feedback – View 1 above – assessing the degree of success in achieving certain goals. It
may at first glance appear more difficult to develop an evaluation instrument based on the
second sort of feedback – View 2 above – according to which feedback helps us create a
new understanding of the world. I suggest that this second role of feedback is part of
what it means to be an organization that learns. To the degree to which our evaluation
criteria satisfactorily address our values and processes they will also address the
effectiveness of feedback in this second sense. But this is a topic for another discussion.

Feedback from Group about Individual
This cell represents evaluation of an Individual by the Group (feedback from the group about an
individual). The relevant goals are those of the group, the source of the feedback. In addition to
specific group deliverables, process criteria for group membership and participation may be
relevant evaluation items.
Example – Row 2, Column 1

Feedback from Individual about Group
This cell represents evaluation of a Group (e.g., a LOG or LOST) by an Individual (feedback from
the individual about the group). In this case the individual is providing to the group information
about the degree to which the group has supported or inhibited the individual’s contribution to the
group’s success (e.g., openness, receptivity to ideas, personal support) and, optionally, the
degree to which the group has supported his or her individual goals.
