Just consider the dramatically lower spending on travel that has accompanied the shift from physical meetings and events to virtual ones. It can eliminate unproductive costs (often as much as 10 to 25 percent of SG&A in six months), allowing owners to reallocate capital to growth, through marketing, sales, and M&A. And ZBB is a standardized and replicable playbook that can be rolled out across a portfolio of companies, ensuring aligned processes, controls, cadences, and incentives.
- Zero-Based Analysis is not about blue-sky thinking, brainstorming, or creating unrealistic expectations.
- Determine a survival minimum, defined as the organizational capacity needed to keep the lights on for the business.
- As expected, the improvement in reconstruction skill with higher model resolution is larger over coastal regions than in the open ocean.
- Table 4Skill scores computed between CMEMS-LSCE and GLODAPv2.v2022 in AT, CT, and pH over the period 1985–2021.
Mean model–data difference (bias) and root-mean-square deviation (RMSD) between the reconstruction and GLODAPv2.2022 surface data (0–10 m) at a spatial resolution of 0.25∘. This means that you start at 0 and do not use the previous year’s values as a basis, as is the what are the income tax brackets for 2021 vs 2020 case with classical budget planning. This means that the financial resources for the next planning period are always reconsidered. As a first step, companies should update their chart of accounts and their accounting rules to consolidate expenses by cost category.
Disadvantages of Zero-based Budgeting
For each region, spatial distributions of pCO2 (μ) and uncertainty (σ) estimates and the coastal–ocean RMSD of pCO2 averaged over 1985–2021 (Eqs. 5 and 10) are shown. Metrics present in the legend for each of the third rows include the number of coastal–ocean SOCATv2022 data (N), regional RMSD (Eq. 10), and r2 (Eq. 11). Table 1Input data used in the reconstructions of CMEMS-LSCE carbonate system variables over the global ocean in 1985–2021. The decision about whether to roll ZBB out company-wide versus in individual business units or regions is mostly driven by specific business needs.
- One major retailer with more than 1,000 locations, 100,000 employees, and $15 billion in annual revenues sought to support its organizational transformation by starting from a clean sheet.
- With the reconstructions of pCO2 and AT (Sects. 3.1 and 3.2), the CO2SYS.v2 speciation software is used to derive pH (on total scale), CT, Ωar, and Ωca and to determine their uncertainty over the ocean surface at a resolution of 0.25∘.
- The workforce is performing tasks in ways that have been passed down from previous generations.
- Approximately $4 billion in savings was generated from acquisition program eliminations, while reductions and delays in acquisition programs accounted for another $11 billion.
Budget planning for the current/next year is usually based on budgets from previous years. In fact, traditional budgeting begins with the previous year’s budget and usually implements incremental percentage increases or decreases to meet new goals. Surface ocean pH and saturation states with respect to aragonite (Ωar) and calcite (Ωca) are critical indicators used to measure ocean acidification.
Zero-based thinking forces companies out of “budget thinking” which we define as an acceptable, budgeted range of failure. The biggest advantage of zero-based budgeting is that it enables cost control. By not using the previous year’s budgets as a baseline, expenditure can be better scrutinised. Those responsible are thus forced to justify their expenditures, which in turn contributes to cost optimisation. Typically, budget planning is done with zero-based budgeting for a certain period in advance, e.g. for a month or for a quarter. In zero-based budgeting, it is always necessary to justify why one is using which resources for a particular purpose.
Understanding DoD’s Defense-Wide Zero-Based Review
Consequently, the Fourth Estate has few defenders in the face of many vocal critics, who have tried time and time again to cut its funding and reduce its size. Zero-based budgeting must be a collaborative, unanimous decision within the company after careful consideration of its relative advantages and disadvantages. ZBA then compares this “perfect world” scenario to the current project plan to identify all the opportunities within the project scope, design, execution strategy, schedule and budget. It “turns over every rock” to get every possible source of opportunity on the table.

Zero-based productivity—Organization: Using zero-based principles to forge a purpose-built organization
The result of the two previous advantages is, at best, a higher increase in turnover. This is achieved on the one hand through more efficient cost control, and on the other hand by questioning past business practices, which can increase process efficiency.

The resulting purpose-built enterprise ensures that staff and resources are allocated to the highest-value areas of the business. As a model for government spending, President Jimmy Carter instituted zero-based budgeting during his tenure as governor of Georgia and installed the process in the federal government as part of his 1976 campaign promise to balance the federal budget by 1981. However, critics contended that the system yielded few results and “required excessive expenditures of time and effort,” and it would later be abandoned under President Ronald Reagan. This change may lead to higher turnover rates and negative changes in brand perception. The third condition involves total concentrations of both conservative and non-conservative constituents in the non-CO2 acid-base systems.
Their approach yielded global σ averages of 17.8 µatm, 11.5 µmol kg−1, 0.018, and 0.110 for pCO2, normalized CT, pH, and Ωar, respectively. 10, we present annual global means of surface ocean pH and saturation states for aragonite (Ωar). For each variable, the calculation of annual global area-weighted means of best estimates (line) and 1σ uncertainties (envelope) follows Eq. The trends reported in the legend result from linear least-squares regression on annual global means of 100 ensembles of the carbonate system variables. These ensembles are generated with a Gaussian distribution having the mean and variance as the best model estimate μ and squared uncertainty (σ2) at monthly time steps and 0.25∘ grid cells, respectively.
Temporal means of the model best estimate and 1σ uncertainty per grid cell over 1985–2021 are calculated by using (Eq. 5). Figure 1CMEMS-LSCE-FFNN pCO2 over the global ocean at a spatial resolution of 0.25∘. Unlike the “Night Court” process, which targeted FY 2020 Army acquisition program funding for the majority of its adjustments, savings in the Fourth Estate would have to be generated largely through structural and process reforms. Such reforms would be unlikely to yield significant savings immediately, and reductions to some organizations’ budgets would still require time and political capital. For example, health care for servicemembers is administered by the Defense Health Agency (DHA), which—as shown in Figure 5—accounts for more than $30 billion of the Fourth Estate’s total funding.
What is Zero-Based Budgeting (ZBB)?
Recent years have seen the rapid development of machine learning approaches to map global surface ocean pCO2 (see Rödenbeck et al., 2013; Landschützer et al., 2016; Denvil-Sommer et al., 2019; Gregor et al., 2019; Chau et al., 2022b, for instance). Thanks to these efforts, the carbon cycle community can now draw on an ensemble of reconstructions for the observation-based assessment of the ocean carbon sink (Friedlingstein et al., 2022). However, only a few global observation-based reconstructions are available for pH, AT, CT, and Ω with respect to calcite and aragonite (see Gregor and Gruber, 2021, for a review).
