IV.3 Types of Budgeting Systems

🎯

Past paper: 2025 Q5a (line-item) and Q5b (performance). Memory ladder: Line-item (inputs) → Performance (outputs) → Program (objectives) → Outcome-based (impact). ZBB = justify from zero.

Incremental Budgeting — Definition, Features, Advantages and Limitations

Definition: A pragmatic approach that uses an existing budget or expenditure base and negotiates marginal increases or reductions for the next period.

Key features

• Historical baseline: continuing activities start from an accepted previous allocation or actual expenditure.
• Marginal adjustment: attention focuses on changes for prices, staffing, workload and policy commitments.
• Bargaining: finance officials, departments and political leaders negotiate changes; public participation is possible but not guaranteed by this method.
• Performance link: the baseline can remain weakly tested against results, although incrementalism can coexist with performance indicators. It is a decision method, not necessarily an input classification.

Advantages

• Simplicity and administrative economy: less information and re-justification than reviewing every programme from zero.
• Stability and predictability: supports continuity in established public services.
• Reduced conflict: agreement over the baseline narrows negotiation to proposed changes.

Limitations

• Inherited inefficiency: weak programmes can retain funding because past allocation is treated as an entitlement.
• Innovation and reprioritisation: small adjustments may preserve outdated activities instead of supporting better alternatives.
• Budgetary slack: departments may overstate needs or defend unnecessary spending to protect next year's base.
• Weak performance linkage: more funding does not automatically require better outputs or outcomes.
• Inflation risk: the method can adjust for inflation, but inadequate or uniform adjustments may ignore different cost pressures. A 5% increase when relevant input costs rise 10% reduces real purchasing power.

Remedy: combine continuity with periodic baseline reviews, spending evaluations and performance evidence.

📄 (a) Line-Item Budget (2025 Q5a)

• 📖 Definition: the oldest, simplest form — lists objects of expenditure (salaries, rent, fuel) line by line.
• Focus: control of inputs — "how much on what item."
• ✅ Pros: simple, easy to prepare and audit, tight control.
• ❌ Cons: ignores results / output; incremental; no link to performance.
  • Example: a household budget saying "Rs X on groceries, Rs Y on electricity" — controls spending but says nothing about what was achieved.

📈 (b) Performance-Based Budgeting — Definition, Principles and Merits

Definition: Budgeting that uses performance information to connect resources with objectives, activities, outputs and intended outcomes. Results inform allocations rather than mechanically determining them.

Core principles

• Results orientation: assess what services and benefits spending produces.
• Indicators: use cost, volume, quality, access and outcome measures to assess efficiency and effectiveness.
• Accountability: assign responsibility for delivery and require explanations of deviations, recognising factors beyond managers' control.
• Strategic planning: connect annual allocations to multi-year objectives and credible targets.

Merits

• Efficiency and effectiveness: helps compare costs and results and identify improvements.
• Transparency: publishing intelligible targets and results supports scrutiny.
• Better decisions: evidence improves prioritisation and evaluation, alongside legitimate political choices and equity considerations.

Measurement and resource challenges

Reliable indicators, baselines, trained staff and information systems require resources. Quantity alone can hide poor quality; outputs do not establish causation for outcomes. The implementation section below covers short-termism, institutional resistance, political incentives and central control.

Illustrative example: report an immunisation allocation alongside children vaccinated (output), cost per child (efficiency), equitable coverage (access), and disease reduction (outcome).

🧩 (c) Program Budget

• Organises the budget by programmes / objectives (e.g., "malaria control programme") — groups all costs of achieving one goal together. Part of PPBS.

🔄 (d) Zero-Base Budgeting (ZBB)

• Every rupee justified from zero each year (no automatic carry-over) — reduces waste but is time-consuming.

🎯 (e) Outcome-Based Budget (OBB)

• The most modern form — links spending to final outcomes / impact on citizens, not just outputs.
  • Example: a performance budget counts "children vaccinated" (output); an outcome budget measures "fall in child mortality" (real result).

📝 Extra notes

• PPBS (Planning, Programming, Budgeting System) was introduced in the US Department of Defense in the 1960s; ZBB is associated with Peter Pyhrr (Texas Instruments, 1970) and later US government use.
• Incremental budgeting (Wildavsky, The Politics of the Budgetary Process, 1964): most budgets change only slightly from year to year — explains why line-item budgets persist.
• Gender-responsive and green budgeting are add-on lenses.
• Pakistan: budgets are traditionally line-item with movement towards medium-term and results-oriented frameworks. 🔎 Verify current practice.

🧪 Worked example — the same health allocation in four formats

• Line-item: salaries Rs 6m, medicines Rs 3m, equipment Rs 1m.
• Performance: Rs 10m to vaccinate 100,000 children (Rs 100 per child).
• Programme: Rs 10m for the immunisation programme, including staff, vaccines and outreach.
• Outcome: Rs 10m to reduce under-five mortality from X to Y over three years.

🔑 V. O. Key's question and the attempts to answer it (2022 Q4)

• The question (V. O. Key, 1940, 'The Lack of a Budgetary Theory'): on what basis should resources be allocated to activity A instead of activity B? No single agreed theory exists.
• Attempts to answer it (learn at least five):
  • Line-item: control of inputs — allocate by object of expenditure and last year's base.
  • Performance budgeting: cost per unit of output and workload.
  • PPBS / programme budgeting: compare alternatives against objectives using cost–benefit or cost-effectiveness.
  • Zero-base budgeting: every activity justified from zero through decision packages and ranking.
  • Outcome-based (results) budgeting: allocate by impact on citizens.
  • Incrementalism (Wildavsky): bargaining and small adjustments — a description of how budgets are usually made.
• Which suits public administration? None alone. Defend a mix: line-item controls for probity, performance and outcome information for results, selective zero-base review for ageing programmes, and political choice for final priorities. Add a Pakistan example (medium-term budget framework; 🔎 verify current practice).
• Dissensus budgeting (2016 Q8c): a label for budgeting when actors disagree about goals and priorities, so allocations come from bargaining, trade-offs and compromise rather than one agreed rule. It describes political conditions; it is not a standard technical format like line-item or ZBB, so say so to avoid overclaiming.

Deeper understanding — budgeting systems can coexist

A programme budget can retain line items for financial control and performance indicators for review. Classification, decision method and performance information are separate dimensions; budgeting systems are not a simple ladder in which each new form eliminates the old one.

ZBB uses decision units and packages to justify activities and alternative service levels. Applying exhaustive zero-based review to every activity annually can be impractical; selective reviews can be more manageable. Incrementalism is a method of adjusting an existing base, not an unavoidable property of line-item presentation.

Original common example: for immunisation, line items show staff and vaccine costs; programme classification groups those costs; output measures count completed vaccinations; outcome measures examine disease reduction and equitable coverage. Outcomes also depend on factors outside the department's control.

Performance-budgeting risks: gaming indicators, neglecting unmeasured quality and attributing all outcomes to spending. Use a small balanced set of indicators and explanatory evaluation.

Answer structure: compare focus, information required, benefit and limitation using the same service throughout. Pakistan's official circular includes medium-term/performance material; distinguish stated framework from implementation quality. 2026–27 Budget Call Circular.

Performance-Based Budgeting — Challenges and Pakistan Implementation

• Short-term target bias: pressure to show quick results can divert attention from prevention, maintenance and long-term capacity. Pair annual milestones with multi-year outcomes and quality measures.
• Institutional resistance: established routines, fear of sanctions and loss of discretion can turn performance reporting into a paperwork exercise. Leadership, training and learning-oriented reviews help embed its use.
• Political and administrative incentives: performance evidence may be produced but ignored when allocations are negotiated. Use it transparently in reviews while recognising legitimate political choices over equity and priorities.
• Central control versus responsibility: holding managers accountable for results while denying operational discretion weakens the link between authority and responsibility. Permit bounded flexibility within spending ceilings and financial safeguards; decentralisation alone does not guarantee better outcomes.

These are implementation risks to assess, not proof that every Pakistani department has the same weaknesses. OECD implementation challenges, OECD managerial flexibility and accountability.

Pakistan — adoption versus implementation: Do not write that performance budgeting has simply “not been adopted.” Finance Division publishes a Medium-Term Performance Based Budget, and its FY2026–27 instructions link PAO strategic plans, outputs, responsible organisations, indicators and targets to indicative ceilings. The analytical question is how effectively this information influences allocations and management, rather than whether a formal framework exists. Official budget documents, Budget Call Circular.
