Therefore, at the outset, the need is first and most importantly to establish perspective. Intuition, creativity and imagination can then be more valuable than exact, factual information. One could therefore turn the problem around and argue that the lack of information early on can actually, rather than a hindrance, be a benefit by providing focus and flexibility to the analysis. Moreover, the validity of information may be a problem.
It is obvious, as experience confirms, that the more precise information is, the more rapidly it becomes obsolete. It is tempting to speak of information half-life. For example, in a rapidly expanding market, the value of information on demand as a basis for planning may depreciate within a few days.
At the same time, the validity of qualitative measures often is more durable than precise quantitative information. Consider, for example, the basic perceptions of the needs of user groups. We may know little about the urgency of the need but can be certain that it will persist for a long time.
Therefore, it may be included in initial assessments. Omitting details and less-relevant information helps avoid analysis paralysis. This is yet another argument for avoiding drowning the initial process with detailed, quantitative information. The lack of quantitative information ex ante leads to no great lasting problem. The need for precise and detailed information increases with the advance of the process. Later, such information will be more readily available Williams et al.
Commonplace opinion holds that the quality of a decision base is decisive for decisions. Experience suggests that decision makers often are less affected by decision bases than what one would think is desirable. The practical implications of this are not necessarily disastrous.
Several studies have shown that in many situations, intuition is preferable to rational analysis, particularly when the decision situation is complex, as is often the case in large investment projects. The assumption then is that intuition is based on experience and training. If the decision maker has the needed relevant professional experience in the sectors involved, intuition can help make sound decisions more rapidly. However, we cannot expect effective intuition without thorough knowledge of the theme at hand.
In turn, that characteristic involves many years of experience combined with workable analyses. Early on, it is essential to establish the best possible understanding of reality as a basis for identifying a suitable strategy. Subsequent critical steps include identifying the overall framework conditions that should guide subsequent decisions on the choice of concept and then the necessary framework conditions that should guide the planning and shaping of the project.
That framework and conditions are the specific solution of the problem at hand—in other words, what the project is to deliver. In such a stepwise process, it is advantageous to choose an approach with corresponding increases in degree of detail and level of precision of information. The challenge is to acquire the essentials and limit the magnitude of what is communicated.
This improves communication and increases the likelihood of the evaluation results being used. The Pareto Principle, also known as the 80—20 rule, may be used to illustrate information needs. The notion is that in a cause-effect relationship, a vital few causes lead to the greater part of the consequences.
To clarify these causes is the central challenge. An evaluation involves an assessment employing specific evaluation criteria and measures against standards or expected values such as knowledge and proficiency relative to learning goals or effects relative to strategic plans. A much-used evaluation model is based on five evaluation criteria that together express the degree of success, OECD Evaluation according to this evaluation model highlights 1 the need for the project relevance , 2 whether the uses of resources and time are reasonable efficiency , 3 whether expectations are fulfilled effectiveness , 4 what other positive or negative effects may occur because of the project impacts , and 5 whether the positive effects persist after the conclusion of the project sustainability.
Evaluation typically involves a process in which overriding evaluation criteria are disaggregated into more-detailed evaluation questions that are relevant to the conditions to be evaluated. Then, information is acquired that answers the questions. Finally, the information is aggregated to support conclusions relative to the overriding evaluation criteria Fig.
Evaluation is part of an information process based on overriding questions and, through analyses and decision making, results in actions at the detail level. This is an example of goal-oriented evaluation, which is one of many possible approaches to evaluation. The model is principally intended for application in the ex post situation, but it conceivably could be even more beneficial ex ante, in the front-end phase. The question that arises is to what extent have we sufficient information at an early stage to be able to apply these evaluation criteria in an ex ante evaluation of a project.
Likewise, it is not known whether the conditions in the implementation phase will permit achievement of the desired result. Not least, the difficulties of planners and decision makers in estimating realistic costs provide a clear message that we often have a poor basis for assessing effectiveness at an early stage. The situation is much the same for efficiency or goal achievement.
We are expected to have a clear idea about the first-order effects that we want to achieve with the project, but in this area, we are also notoriously bad at producing realistic estimates and estimating the effect of external factors that could affect the process and thus the achievement of objectives. It is even more difficult to estimate impacts early on. Studying similar projects doubtless provides knowledge based on experience.
However, we then are likely to face conditions that are difficult to predict and may require imagination and ability to guess beyond our capabilities. The situation for relevance differs. Early on, common sense combined with for example studies of priorities and needs in society, market demands, legislation and regulations, can provide a solid picture at an early stage of whether the measure is relevant. However, this will require openness and a thorough analysis at the beginning.
Additionally, needs and priorities clearly may change in the future and may be difficult to predict. Finally, future sustainability is somewhat more difficult to assess. However, the question is closely associated with the relevance of a project. Moreover, people tend to do reasonably well in realistically assessing future needs and resources, not least in the form of cash flow analyses.
The conclusion then is that with reasonable effort, we can obtain a good picture at an early stage of whether a proposed project is relevant and sustainable, but to a greater degree, we must disregard the other three criteria. The good news is that relevance and sustainability are precisely the two aspects that are most crucial to whether a project will succeed.
Consequently, such a delimitation of an ex ante evaluation will, therefore, be the minimalist answer to what might be an appropriate approach, not least because the benefit relative to resource allocation will be quite high. The discussion above concerns improving the basis for planning and decision making early on based on ex ante evaluation.
The picture is simplified by being limited to goal management techniques developed in the implementation of projects. However, an ex ante evaluation that is conducted at a sufficiently early point in time and with the necessary openness is, as mentioned above, no guarantee that the best alternative is chosen. Decision processes take time, in many cases months or years.
Often, several parties with divergent assessments and preferences are involved, new problems and solutions arise and conditions change. Therefore, they are often complex and the answer unpredictable. The patterns evident in such processes are called decision logic, a phenomenon that has been researched for many years. Such an analysis provides deep insight into the conditions for ex ante evaluation and, not least, affords reflection on the public quality assurance scheme, particularly the part applicable to the quality assurance of the choice of concept QA1 but also the part that pertains to the quality assurance of the management system QA2 , which clearly has ex ante features.
At the same time, such a unified decision analysis provides clear terms for ex post evaluation and what may be learned about the organization of the processes in major public investment projects. There five defence projects and a variety of other projects, including a cultural centre, a research centre, two hospitals and two sports facilities. The analysis is broad and brings in several elements of events in the front-end phase.
The presentation and discussion is principally of the experience addressing decision analysis. The focus is on the characteristics of the front-end phases of the projects as decision processes and how they may be understood, interpreted and explained. The evaluation technique is emphatically analytical, in the sense that the front-end phase is interpreted through the following four organizational theory perspectives or decision logics.
Instrumental logic. The actor may be a high-ranking leader in the public or private sectors. Institutional logic. This logic emphasizes the importance of historical traditions, path dependence and informal decision norms that may modify or tie up instrumental logic Selznick Environmental logic. This logic emphasizes that temporary or long-term occurrences in environments press upon and influence public decision processes, both of a technical and institutional nature Meyer and Rowan Contingency logic, often also called garbage can theory March and Olsen Instrumental logic incorporates two main aspects of concern in the front-end phases of major public investment projects: political or administrative control and rational calculation.
Accordingly, the ideal for a decision process will be that governmental leaders act based on clearly defined problems and goals, clear views of the possible means and solutions and, not least, the potential consequences of choosing one or another alternative.
Ex ante evaluation should be able to induce clear thinking and management in accordance with these ideals. Political and administrative control may be understood as two forms of decision logic: 1 leaders have clear hierarchal control over the front-end phase or 2 leaders and public institutions in part have dissimilar interests and initiate negotiations to hammer out compromises March and Olsen To what degree does the front-end phase reflect the degree of leadership agreement and firm hierarchical control of the processes?
The answer is that it varies considerably between and within various types of project. The selected regional and local road, tunnel and bridge projects most strongly reflect the involvement and control of political leaders, most often in interaction and agreement with regional and local competent authorities, that is, The Public Roads Administration. The opposite is true of large defence projects that are characterized by insufficient authority and breakthrough for central executive political and administrative leaders and considerable disagreement with military sector authorities.
In other projects that are concerned with for example culture, sports, research, and hospitals, there are clear variations in the degree to which central political leaders break through. Overall, it is surprising that the Government was not more-centrally involved in many of the projects. However, expert authorities are systematically central, which indirectly suggests a considerable potential influence, because of the shared norms among political and expert leadership.
What of tugs of war and negotiations, primarily within the political-administrative apparatus, occur during the front-end phases of projects? These essential aspects underscore the limits of hierarchical control. In the group of road projects, negotiations between political and administrative regional and local actors are vital. Thus, there are many tugs of war to balance the interests of the involved parties and municipalities, which lead to choices between alternatives and alignment adjustments during a project.
These negotiation processes are also important because agreement must prevail to contribute funding and because concurring views are vital towards the State to obtain support in the form of subsidies and toll systems. In military projects, there is more internal disagreement than actual internal negotiation processes, whereas other projects such as the New Opera House, the Regional and the National university hospitals exhibit a clear internal negotiation process.
The question of rational calculation is tantamount to asking whether the front-end phases of the projects are characterized by clear, well thought-through analyses. The main answer must be no. In approximately half of the projects, the planning and preparations lack many of the features outlined above.
Only one-fourth of the projects approach the ideal. For these projects, considerable potential exists for an ex ante evaluation that would contribute to greater clarity in the reasoning about the projects. There are many difficulties in the reasoning about the projects. In many of these projects, both problems and solutions were expanded during the project. True, the projects vary considerably in size and complexity, but that seems not to be decisive for how they score on rational calculation.
The instrumental logic aims to explain most of what happens in the front-end phases of projects, particularly in the form of hierarchical management or negotiations but also in rational calculation. This logic most often dominates reasoning on the conduct of rational processes, either in what may be called bounded rationality or in the more concise economic version of it.
Its core lies in public organizations having gradually developed sets of informal norms and values through mutual adaption to internal and external pressures. Through this institutionalization process, a unique culture or identity evolves in an organization. Reasoning concerning path dependence is central in institutional logic.
Another position holds that when an institutionalized organization encounters pressure for change or reform, it will react according to the degree to which the impetus for change agrees with its cultural traditions March Changes or reforms are more easily accepted when there is considerable agreement. With this logic, ex ante evaluation can either point to the necessity of cultural sensitivity in projects or consciously depart from the established cultural track and eventually be innovative.
Military projects exhibit this sort of logic to a great degree. In building the Skjold-class coastal corvettes, the frigates and the Malangen torpedo battery, the point of departure for the competent authorities should have considerable institutional continuity to commit to the same type of military platform.
This has contributed to considerable investment in military vessels that are militarily unnecessary or cost too much to operate. This is a negative aspect of tradition and cultural continuity. However, in many other projects, cultural factors conceivably may contribute to strengthening a project. Culture theory also includes elements of shocks and unbalanced development Kingdon , implying that public organizations may long follow the same cultural path.
However, then comes a dramatic period of change that ends with choosing a new path that thereafter is characterized by continuity Aberbach and Christensen ; Baumgartner and Jones Such a change of path may be brought about by internal changes, such as a change of Government or political majority, but also may be due to sudden external changes or shock.
In the 23 projects analysed, there are several such breaks. There was also a critical break after many stages of expanding the National University Hospital in downtown Oslo, in which the new location in the outskirts beyond the main beltway was a radical solution. The opposite is true of the location of the new Regional University Hospital being tied to the city of Trondheim. The lesson learned in the use of such logic and the other logics is that there never are only advantages or only disadvantages associated with assessing projects from such vantage points.
Institutional and cultural continuity may have clear advantages in many projects because they include a form of institutional intelligence; over time, the institutions have become skilled at adapting, which may inform the ex ante evaluation Boin and Christensen ; Kaufman Activities and efficiency may be improved by following or slightly modifying the historical path.
However, the path also may impose a form of trained incapacity or inertia whenever a public organization is too rigid or old fashioned in meeting new challenges, or when it is better at some point to forsake the old path and start anew. In several military projects, this did not happen. The results were cost overruns and failures. Environmental logic focuses on how decision-making processes, in this case those in major public investment projects, are influenced by their ambient environments Meyer and Rowan This can happen whenever occurrences and actors in the environment intervene in processes and exert pressure to bring about particular solutions.
With such logic, an ex ante evaluation can either contribute realism related to external conditions, such as resources and time, or may contribute to building images of the worth of particular project solutions. The clearest examples of the importance of environments are evident in military projects such as the Skjold-class coastal corvettes, the frigate project and the new fighter aircraft. The large coalitions that were established were decisive in the outcome. Sectoral military leadership allied itself with the principal defence politicians of the Conservative and Labour parties and the Confederation of Trade Unions, often against executive political leaders and the Chief of Defence.
The motives of the coalition focussed on employment for external actors, which defocussed the suitability of projects in terms of other considerations. Throughout, this contributed to costly bad investments, at least for two of these projects.
Another type of environmental mechanism was at play in the new Holmenkollen winter sport arena, namely pressure from national and international ski federations, which greatly inflated costs. In the 23 projects investigated, there have been relatively few negative effects from external influences, but again this observation cannot be generalized to infer that such pressure is undesirable.
Alliances with private actors can be necessary and useful. The State placed considerable pressure on the Municipality of Oslo and on various public and private developers, who together in a coalition are committed to urban development around the Opera, with apartments and commercial buildings. This form of win-win situation is one in which all concerned parties gain and commit themselves. Contingency or garbage can logic entails a profuse mix of problems, solutions, participants and decision possibilities that come and go, in which actors face capacity and attentional problems and decisions appear to be incidental March and Olsen A characteristic of contingency logic is that problems and solutions are associated and dissociated, or decoupled and recoupled, and have effects on decisions.
Another aspect is that the structures of problems and solutions are particularly complex and unclear. A third aspect is that solutions come before the problem. In an ex ante evaluation, all such features can lead to deviation from strong management and clear thinking. However, the sequence came about deliberately, not by chance. When the Opera was proposed for approval, it was important to dissociate it from the road project, which was so expensive that it might not have gained financing.
The Opera was publicised as a unique, isolated project, although almost everyone realized that the development of the surrounding area presupposed a road solution such as the immersed tube tunnel that finally was chosen, and, not least, further urban development Whist and Christensen Once the new Opera project was approved, the road project was again proposed on the strength of arguments including seeing the new Opera as part of a greater urban development.
Four of the transport projects—the two railway projects around Oslo, the Hardanger Fjord suspension bridge and the Ryfast road project—also have elements of dissociation and association to increase the chances of realization. These examples are characterized by organized anarchy in which some actors consciously exploit association and dissociation rather than letting chance rule.
There are also several examples of other characteristics of such logic. The structures of problems and their solutions are complex and unclear for E6 Norther beltway, the Jondal road tunnel and the Stad shipping tunnel. Perhaps the Stad shipping tunnel is the foremost example of a solution arising before a problem, but that is also the case for the Arctic Research Park on Svalbard. The foremost examples of local rationality are several of the major defence investment projects in which the projects are not set in a greater picture of military or social needs.
Ex ante evaluation is needed to link the decision processes to the results of overriding reasoning based on facts and systematic analysis. The result of a decision-making process is not necessarily in accordance with this requirement, as has been shown. The final choice can be better or worse than that recommended at the outset. However, in any case, the best-case result comes from democratic processes that legitimate the outcome.
The criteria for ex ante evaluation are often associated with a rational ideal of strong management and clear thinking. Ex ante evaluations should also build on experience with ex post evaluations, preferably in sufficient numbers to provide a greater scope of experience and, not least, include several alternative courses of action. Moreover, the evaluation criteria in ex ante evaluation correspond to a degree with those of ex post evaluation.
This is particularly important in constructing learning loops that function over time. Not least, it is important that ex ante evaluation is made to a central reference in the subsequent decision-making process against which the various alternative courses of action are evaluated.
This emphasizes various aspects of the processes. The instrumental logic emphasizes two central aspects: 1 the degree to which decision-making processes associated with projects are characterized by political and administrative control, and 2 rational calculation or clear organizational reasoning.
This perspective is the most relevant for explaining the decision-making processes of the 23 projects. They are characterized by considerable hierarchal control and influence but also by internal coalitions and compromises. Conversely, there apparently is a clear potential for improvement, as implied by the prevalent medium to low scorings in rational calculation.
This clearly indicates a potential for strengthening ex ante evaluation. The institutional logic focuses on how history and traditions bind, which provides supplementary insights to those of instrumental logic. Particularly for military projects, the historical path carries weight in winning coalitions, which in turn contributes to decisions on problematic investments.
Employing environmental logic, projects with alliances between the leaders of the armed services and external actors in particular are typical. Contingency logic characterizes several projects, but the contingency is more often steered than basic logic indicates. The evaluations of the front-end phases of 23 projects show that dissimilar logics are coupled in various ways in decision-making processes. Even some of the logics point to problematic decisions, either due to lack of goal attainment or excessive costs; there are examples showing that organization and reflecting in other ways contributes to attaining goals and to legitimacy.

In the field of finance, these terminologies depict the returns from an investment or any other economic activity. Ex-post returns are the returns that an investor has already got from an investment. In other words, it is the actual or historical return from security. Ex-Ante is a prediction of the returns that an investor can get from a security or from a company.
In other words, it is a futuristic prediction. And the prediction can also be with regard to the future performance of a business, security, or policymaking. However, all such Ex-Ante predictions have an element of uncertainty in it. Because one cannot be certain of the returns from a particular security or investment or about future performance.
A comparison of Ex-Ante prediction can be done with the actual results. This will help us to find out the accuracy or deviation from the prediction. Ex-Ante is a prediction and is useful for an investor, a company, the various economic sectors, and the overall economy as a whole. An investor buys a security on the basis of Ex-Ante predictions of analysts, news agencies and portals, trade reports, or maybe of the investor himself.
This helps him to take the right decision to maximize his returns from investment. Similarly, a company makes a number of Ex-Ante predictions on its performance and financial results, market conditions, and demand scenario, amounts receivables and payables, interest rates, and the performance of the economy.
All these predictions help it to attract investors and raise capital. It also helps it to effectively plan what and how much to produce according to the probable demand scenario. It can also calculate its cost of capital as per the future interest rates and cash-flow prediction. Predictions of the future economic scenario can help it to effectively plan in advance for inflation , deflation , or serious situations like a recession. All top level executives, whether in the government or in the corporate, in charge of different sectors of the economy such as agriculture, pharmaceuticals, industry, etc.
It is to determine their future course of action considering the predictions. The Central Bank of a country makes a number of Ex-Ante predictions with regards to interest rates, money supply, Gross Domestic Product, etc. These predictions are the basis for critical policy formulation by the Central bank as well as the government of that country.
Ex-Post is the opposite of the term Ex-Ante. It means after the occurrence of an event. Hence, the term is important for those who rely upon actual or historical results of security for further decision-making. This information can be of use to an individual investor, analysts, investment companies, mutual funds, corporations, and the government and its agencies. Investors and analysts can use Ex-Post data for prediction of future trends, prices, etc. Tools for Fundamental Analysis. Your Money.

Ex-post is another word for actual returns and is Latin for "after the fact. Ex-post is the opposite of ex-ante , which means "before the event. VaR is defined for a specified investment portfolio, probability, and time horizon. Ex-post yield differs from ex-ante yield because it represents actual values, essentially what investors earn rather than estimated values.
Investors base their decisions on expected returns versus actual returns, which is an important aspect of an investment's risk analysis. Ex-post is the current market price , minus the price the investor paid. It shows the performance of an asset; however, it excludes projections and probabilities.
Ex-post is calculated using the beginning and ending asset values for a specific period, any growth or decline in the asset value, plus any earned income produced by the asset during the period. Analysts use ex-post data on investment price fluctuations, earnings, and other metrics to predict expected returns.
It is measured against the expected return to confirm the accuracy of risk assessment methods. Ex-post is best used for periods less than a year and measures the yield earned for an investment year to date. Ex-post performance attribution analysis , or benchmark analysis, gauges the performance of an investment portfolio based on the return of the portfolio and its correlation with numerous factors or benchmarks. Ex-post analysis is the traditional approach of performance analysis for long-only funds.
Ex-post performance analysis typically centers on regression analysis. The beginning value is the market value when an asset was purchased. The ending value is the current market value of an asset. Ex-post is a forecast prepared at a certain time that uses data available after that time. The forecasts are created when future observations are identified during the forecasting period. It is used to observe known data to assess the forecasting model.

Gunnar Myrdal further explained that ex ante disparity and ex post balance are made consistent through price changes, which result from the behavior of economic agents, which is based on ex ante anticipations:. For these anticipations determine the behaviour of the economic subjects and consequently those changes in the whole price system which during a period actually occur as a result of the actions of individuals.
In context of ex-ante , the Swedish economist Myrdal also dealt with the question of the unit of time, which he proposed to solve by reducing the actual time-dimension of macroeconomic variables such as income, saving and investment to a point of time:. Some of these quantities refer directly to a point of time.
That is true of "capital value" as also of such quantities as demand and supply prices. Other terms — as e. But in order to be unambiguous they must also refer to a point of time at which they are calculated. Hodge 46—7. Economist G.
However, the reference to ex ante and ex post analysis has become so usual in modern macroeconomics that the position of John Maynard Keynes to not include it in his work was currently considered as an oddity, if not a mistake. As Shackle put it:. Myrdalian ex ante language would have saved the General Theory from describing the flow of investment and the flow of saving as identically, tautologically equal, and within the same discourse, treating their equality as a condition which may, or not, be fulfilled.
Shackle, G. From Wikipedia, the free encyclopedia. In the recruitment industry, ex-ante is often used when forecasting resource requirements on large future projects. The ex-ante and ex-post reasoning in economic topics was introduced mainly by Swedish economist Gunnar Myrdal in his —39 work on monetary theory, who described it in this way: An important distinction exists between prospective and retrospective methods of calculating economic quantities such as incomes, savings, and investments; and [ Hodge 46 This analysis has become a standard tool in macroeconomics.

Ex-post is a forecast prepared at a certain time that uses data available after that. It is measured against the an asset; however, it excludes accuracy of risk assessment methods.On the other hand, ex-post means “after the event,” while ex-ante means “before the event.” Ex-post is backward-looking, and it looks at results after they have already occurred. For investment companies, analysts can use historical returns to forecast the probability of making a profit or loss on an investment.
