Decisions rarely stand alone. Aircraft hours flown for one purpose are not available for another; a budget spent on one line is gone from the next; a team negotiating one agreement cannot negotiate a second in the same hour. When a record of a decision says so, it has to choose what to name as the tie: a topic the two decisions have in common, a likeness in how they are reasoned, an order in which they should be taken, or a thing they both draw on. It also has to choose what to leave out, and whether to say who settles the claims that each decision makes on what is shared.
This paper asks those questions of one set of records. AEGIS, the safety and protection studio of the RISCON family, publishes 6,540 authored cases, each a decision record with a question, three choices, an author's marked recommendation and a list of what must be known before deciding; 6,070 of them carry at least one link to another case. Only twelve state, in a reason of their own, why they are linked. Those twelve are the subject of this paper. They are authored synthetic training cases, not records of real events: AEGIS types each one realistic synthetic, names every deciding body fictional, and says that every figure in them is the original's or a training assumption. What can be learned from them is how a designed record set frames the tie between decisions, not how any real decision was tied to another.
The research question is this: when the record of one decision says it is tied to another decision, what does it say ties them, what does it refuse to tie, and who is left to decide the thing they share?
The argument in brief
The twelve records form seven pairs. Each record names the case it is tied to, every case named is among the twelve, and in every pair each record names the other. What ties a pair is, without exception, one resource the two decisions are said to share: an annual stock of transport aircraft hours, a sum for allied joint production and cooperation, a budget for stockpiling and procuring minerals, a budget for parts and consumables, an alliance negotiating channel and its budget, a stock of maritime operating time, and a system for sharing information. Each record then closes its reason with the same refusal. Only the stated resource grounds the link, and because nothing else jointly allocated was confirmed, no further link is made.
Around this core of its own, each link borrows the rest of its wording from a template that stands in nearly every link the studio publishes. One of those borrowed sentences says that a comparison does not hold when the two cases differ in owner, deadline or needed materials. In all seven pairs, the two records have different owners and different deadlines. The template was written for another kind of tie, and it does not fit this one.
That mismatch leads to the paper's main finding. The pairs share a resource, but no link names a body that decides the resource. Seven of the twelve records carry the shared resource somewhere else in the record: in the moment before which the decision must be made, in the inputs the decision needs, in the condition on which it would be reconsidered, or in the author's mark. Five mention it nowhere but in the link itself and in the list of cases that closes the situation they describe. The set names what is shared with care and leaves the sharing without an owner.
The debate this paper enters
The question belongs to a long debate about how separate decisions that depend on each other are, or should be, coordinated. Thomas W. Malone and Kevin Crowston, The Interdisciplinary Study of Coordination (1994), proposed to see coordination as the process of managing dependencies among activities, and to make progress by characterising kinds of dependency and identifying the processes that can manage each. Shared resources are one of the kinds they analyse, beside producer and consumer relationships, simultaneity constraints and the dependencies of tasks on subtasks. Their framework gives this paper its first distinction. This paper reads a record that ties two decisions as naming, whether it says so or not, a dependency of a particular kind, and reads the kind it names as bearing on the coordination it would need.
The second strand concerns budgets. Jürgen von Hagen and Ian J. Harden, Budget Processes and Commitment to Fiscal Discipline (1995), model the public budget as a common pool. Spending tends to be targeted at particular groups while the tax burden is widely dispersed, and the externality this creates biases budgets towards excessive spending and debt. Their remedy is a measure of centralisation in the budget process: institutional structures that strengthen a comprehensive view of the budget over the particularistic view of the ministers who spend it. This paper reads that model as saying that two decisions that draw on one budget are coordinated when somebody holds the whole of that budget in view.
A third strand asks whether coordination needs such a centre at all. Fritz W. Scharpf, Games Real Actors Could Play: Positive and Negative Coordination in Embedded Negotiations (1994), argues that there is more coordination in the modern world than community, market and hierarchy plausibly explain, and describes forms of negotiated self-coordination embedded in organisations or in networks of cooperative relationships. Embeddedness, in his account, widens the scope of positive coordination, which seeks the best joint result, and creates conditions under which externalities are held back through negative coordination. Elinor Ostrom, Governing the Commons: The Evolution of Institutions for Collective Action (1990), finds that neither state control nor privatisation has been uniformly successful with resources used by many in common, and that common-pool problems are sometimes solved by voluntary organisations rather than by a coercive state.
The fourth strand is the reform movement that set out to join decisions up. Christopher Pollitt, Joined-up Government: A Survey (2003), identifies the varied meanings and objectives of joined-up government and explores the costs and risks it involves. Tom Christensen and Per Lægreid, The Whole-of-Government Approach to Public Sector Reform (2007), read whole-of-government initiatives as a reaction to the negative effects of structural devolution, single-purpose organisations and performance management, and to a more insecure world. Donald F. Kettl, Managing Boundaries in American Administration: The Collaboration Imperative (2006), holds that boundaries define what organisations are responsible for and what lies elsewhere, names resources and responsibility among the five that have mattered most, and argues that working at boundaries requires new strategies of collaboration.
The last strand is a counterpoint. Michael D. Cohen, James G. March and Johan P. Olsen, A Garbage Can Model of Organizational Choice (1972), describe organisations in which choices look for problems, solutions look for issues to answer, and decision makers look for work. This paper reads such a picture as one in which what joins one decision to another can be a matter of what happens to be present at the same moment as much as of any stated reason. A record set that ties decisions only by a stated reason, and refuses ties of resemblance or of timing, takes a position against that picture, whether or not it means to.
These strands disagree about where the coordination of a shared resource should sit: in a comprehensive centre, in negotiation among the parties, or in institutions the parties build for themselves. As synthetic cases, the records studied here cannot test any of the theories. They can show what one designed record set writes down when it ties decisions together, and so where a reader would find the coordination placed, or find it missing.
Contribution
The paper makes three contributions. First, it gives a measured description of a rare form of link between decision records: a link grounded in one named shared resource, with every other tie refused. Second, it separates that link's own content from the template around it, measuring how much of the link's wording the studio uses in nearly all of its links, and showing that the template and the content do not fit. Third, it shows how far the shared resource reaches into the rest of each record, and finds that the records name what is shared without naming who decides it, the gap that the literatures on common pools and on joined-up government would put at the centre of the question. The paper judges no case and no option, and it gives no advice on defence, budgeting, procurement or alliances.
